3. DEFINITIONS: Terminology used in this specification is intended to be generic in nature and consistent with meanings that have been defined through general use and/or accepted trade practices. Where variant meanings may exist, the applicable interpretation shall be determined by the Texas Procurement and Support Services (TPASS).

3.1. COMMISSION: Texas Procurement and Support Services (TPASS).

4. REQUIREMENTS: The metal-crosslinked polymer floor finish manufactured to this specification shall meet or exceed the following minimum requirements:

4.1. GENERAL REQUIREMENTS: The floor finish shall be produced by the skillful application of modern techniques and equipment to raw materials of high quality, which shall include a metal-crosslinked acrylic polymer, and alkali-soluble copolymer, and a polyethylene, ethylene copolymer or similar type of synthetic wax, together with surfactants, plasticizers, and preservatives, in proper proportions to give an optimum balance of desirable properties as defined below.

4.2. TEST REQUIREMENTS: The product shall conform to the requirements of Table 1, Test Requirements, when tested by the methods cities in Paragraph 5.1.

4.3. STORAGE STABILITY: The floor finish shall retain a homogeneous fluid appearance, without creaming, gelling or separating, and shall develop no offensive odor, during storage in unopened container under normal conditions for a period of nine (9) months from date of delivery.

5. TESTING: Testing shall be done by or at the direction of, the Commission and/or the receiving State agency. Tests shall be performed on products from shipments to ordering agencies. In the event products tested fail to meet or exceed all conditions and requirements of this specification, the cost of the samples used and the cost of testing shall be borne by the supplier.

5.1. TESTS: The product furnished under this specification shall be tested by the following methods or approved equally applicable procedures:

5.1.1. Total Solids: Determine by the method of ASTM D 2834, using a heating time of four (4) hours.

5.1.2. pH: Determine pH of the material as received by the procedure of ASTM E 70.

5.1.3. Odor: On gentle sniffing at the container opening, there shall be no odor of an acrid, rancid, putrid or other offensive nature.

5.1.4. Sediment: SHAKE OR ROCK THE CONTAINER THOROUGHLY TO STIR UP SEDIMENT, IF Any. Draw a sample from the bottom third of the container. Determine sediment by the procedure of ASTM D 2273, with the exception that two undiluted samples are used for the test. Conical centrifuge tubes suitable for use in this test are available under the designation "Corning No. 8220".

5.1.5. Heat Stability: Pour a 100ml sample into a clean four (4) ounce bottle and close tightly. Leave undisturbed in a constant-temperature oven at 122 F (50 C) for 30 days. Visible evidence of separation or creaming at the end of this period shall constitute failure to pass the test.

5.1.6. Film Characteristics: Pour a 50ml sample of floor finish over a clear glass plate measuring 3 x 5 x 1/4 inch positioned at an angle of 45 to the horizontal. Allow the coated plate to drain and dry for two hours in a nearly vertical position at a temperature of 70 F ( 2 F) [21 C ( 1 C)] and a relative humidity of 65% ( 2%) in still air. Lightly buff the coating surface with a flannel or other soft cloth. The coating shall show no evidence of whitening or roughness. It shall be practically free from visible particles when viewed from the reverse (uncoated) side of the plate. Mark off with a pencil a rectangular area measuring 3-1/2 x 1-1/2 inches on a resion-coated black test paper. From a 1ml graduated pipette, drip 0.25ml of the floor finish into the area of the rectangle. Distribute the sample evenly over the test area by means of an 8-mil applicator blade. Allow to dry for 24 hours, and examine the coating film. The fried film shall show no signs of cracking, crazing or whitening.

5.7. Spreading and Leveling: Spread a coating of floor finish over the surface of an OTVAT title by the procedure of ASTM D 1436, Method B, using a cheesecloth applicator. The material must spread evenly over the surface without forming ridges or puddle, and dry to give a smooth film of uniform thickness.

5.8. Drying Time:

5.8.1. Coat an OTVAT tile with floor finish by the following procedure: Prepare a paper applicator by cutting a four (4) inch section from a folder paper towel with scissors, starting at an unfolded edge. Saturate one end of the applicator with floor finish to a depth of two (2) inches. Allow the excess to drain for five (5) seconds. Touch the full width of the applicator to the panel at one edge, and pull slowly and smoothly across the surface of the panel to the opposite edge. Then retrace the path of the applicator in the opposite direction.

5.8.2. About 10 minutes after application of the film, touch the coated surface lightly with one finger. If no material is transferred to the finger, as shown by absence of smearing when the singer is subsequently pressed against a piece of clean glass, the film has set to touch. Repeat the touch test at regular intervals up to a maximum of 20 minutes. A set-to-touch time no greater than 20 minutes shall constitute compliance with Requirement 3.2.8. Ambient conditions for this and the following test (5.9.1., Tackiness) shall be a temperature of 70 F ( 2 F) [21 C ( 1 C)] and a relative humidity of 65 % ( 2%), in still air.

5.9. Tackiness:

5.9.1. Coat an OTVAT tile with floor finish by the procedure of Paragraph 5.8.1. One hour later place a piece of glazed paper 1-3/4 inches square face down on the coated surface. Weight the paper with a 200-g brass weight, and allow to stand for one (1) hour. Remove the weight and hold the panel in a vertical position. The paper must fall freely away from the panel to demonstrate absence of tackiness.

5.9.2. Coat a square of white vinyl floor covering by the procedure of Paragraph 5.8.1. One hour later place on the coated surface a piece of glazed paper as above, and a piece of absorbent cotton. Weigh each object with a 200g brass weight. Leave the panel in a constant-temperature oven at 110 F (43.3 C) for one hour. Remove the weights and invert the test panel. Both the paper and the cotton must fall freely without adhering to the panel.

5.10. Flexibility and Adhesion: Coat an OTVAT title by the procedure of Paragraph 5.8.1., and allow to dry for 24 hours. Bend the panel through 180 around a two (2) inch mandrel, with the coated side outward. Any visible sign of cracking or loss of adhesion of the film to the panel constitutes failure to meet this requirement.

5.11. Gloss: Measurement of gloss shall be performed with a 60 specular gloss meter. (Examples of suitable instruments are those supplied by the Gardner Laboratory, Photovolt Corporation, and Aminco-Scott.) A black glass plate is furnished with the instrument to be used as a calibration standard at the high end of the scale. Coat this high-gloss standard with floor finish by pouring, as in the procedure of Paragraph 5.6.1. Allow a drying time of eight (8) hours (minimum). Calibrate the gloss of the coated side. The gloss-meter reading shall be no less than 87 scale units.

5.12. Color of Film: Initial color and tendency to discolor on aging are to be evaluated in terms of reflectance reading on coated white pure vinyl floor covering material. Suitable reflectometers, operating at a 45 angle of incidence and a 0 angle of view, are available from Gardner Laboratory, Inc.; Hunter Associates Laboratory; and Photovolt Corporation.

5.12.1. Cut a piece of clean white OTVAT vinyl tile measuring at least 9 x 4-1/2 inches. Using the blue filter, take reflectance readings at four different points on the panel, and determine the average value (B). Take four more readings using the green filter, and determine the average value (G). Calculate whiteness value by the formula:

_ _ _ _

W1 = 100 - { | 220 (G-B) | 2 + | 100-G | 2 } 1/2

|_ G + 0.242B _| |_ 2 _|

5.12.2. Apply a coating of floor finish to the panel by the procedure of Paragraph 5.8.1., and allow to dry for one hour. Apply a second coating, and allow to dry for 24 hours.

5.12.3. Determine whiteness value as above, for the coated panel (W2). Calculate percent loss in whiteness by the expression:

100 x (W1 - W2)


This figure shall be no greater than two percent (2%).

5.12.4. Allow the coated tile to age for seven days under normal room conditions, including exposure to artificial light. Determine whiteness value as above. Reduction in whiteness due to the coating and aging processes together shall not exceed three percent (3%) of the original whiteness value for the clean, uncoated tile.

5.13. Water-spotting Resistance:

5.13.1. Apply a coating of floor finish to a black OTVAT panel by the procedure of Paragraph 5.8.1., and allow to dry for one hour. Apply a second coating, and allow to dry for 24 hours.

5.13.2. Measure 0.3 ml distilled water from a graduated pipette onto the center of the panel. Allow the puddle to stand for one hour, then remove the remainder by blotting with absorbent cloth or paper, and allow to dry another hour.

5.13.3. On close examination, there shall be no evidence of penetration of the film by the water, leading to softening or separation from the panel. Any whitening of dulling of the surface must be removable with light buffing.

5.14. Rubber-marking Resistance:

5.14.1. Coat a white OTVAT tile with floor finish by the procedure of Paragraph 5.8.1., and allow to dry for one hour. Apply a second coating, and allow to dry for 24 hours.

5.14.2. Select a clean, black rubber stopper of the type commonly used in chemical laboratories. Draw one edge of the stopper firmly across the coated surface of the panel, in order to produce several black "scuff marks". Buff these marks vigorously with a clean, unsized terry cloth, applying sufficient pressure to remove the marks. Any such marks must be removed completely with no visible damage to the floor finish film.

5.15. Slip Resistance:

5.15.1. Coat a 9 x 9 inch black OTVAT tile with floor finish by the pouring procedure of Paragraph 5.6.1. After two hours, rotate the panel through 180 in its plane, apply a second coat, and allow to dry from 12 to 24 hours.

5.15.2. Determine static coefficient of friction with the James Machine, according to the procedure of ASTM D 2047. the average of four determinations, each as a different orientation of the test panel, shall be no less than 0.5, and no individual determination shall be less than 0.45.

Note: Classification of the floor finish a "slip resistant" by Underwriters Laboratories, Inc. will be accepted as evidence of compliance with this requirement.

5.16. Wet Traffic Resistance: this test employs the Gardner Straight Line Washability and Abrasion Machine, supplied by Gardner Laboratories. The hog-bristle brush used in the test should be soaked in distilled water for ten minutes before a run.

5.16.1. Coat a black OTVAT tile with floor finish by the procedure of Paragraph 5.8.1., and allow to dry for 24 hours.

5.16.2. Mount the tile in a tray of the Gardner machine, with a clean tile at each end for bracing, attach the brush, and start the machine. Keep the test surface wet with distilled water, dispensed dropwise from a buret or pipette.

5.16.3. Examine the coating for signs of wear at regular intervals up to a maximum of 1500 brush strokes with the machine. The coating shall withstand 1500 strokes without significant damage, other than slight whitening which disappears on buffing with a soft cloth.

5.17. Removability: The test procedure is based on ASTM D 1792, which uses a solution of soap and ammonia to remove the floor finish coating in a measured number of brush strokes on the Gardner straight-line washability machine. the mechanics of the test are the same as in Paragraph 5.16.

5.17.1. Coat a black OTVAT tile with floor finish at a rate of 0.4 ml per 8 square inch surface (50 cm2), and prepare it for testing by the procedure of ASTM D 1792, Paragraphs 6.2. and 6.3.

5.17.2. Test for removability by the procedure of ASTM D 1792, Paragraph 6.4, using a standard soap solution prepared in accordance with Paragraph 4.1. of the same standard.

5.17.3. The coating shall be completely removed by 50 brush strokes of the Gardner machine.

6. SAMPLES: Unless otherwise specified in the Invitation for Bids, no prepurchase samples shall be required. Samples tested shall be taken from regular orders.

7. INSPECTION: Products furnished under this specification shall be inspected by, or at the direction of the Commission and/or the ordering State agency either at the destination or place of manufacture.

8. PACKING / PACKAGING: Packing for shipment shall be in accordance with the manufacturer's standard practice and in a manner readily accepted by common carriers engaged in interstate commerce. Within the shipping carton, units shall be packed in a manner designed to minimize damage during the shipment because of rough or improper handling.

8.1. PACKAGING: Packaging shall be in one of the following types and sizes of containers, as specified in the Invitation for Bids:

(1) 1-gallon (3.79 liters) plastic jugs (six per case)

(2) 5-gallon (18.9 liters) plastic jugs or drums

9.2.4. Name and address of manufacturer.

9.2.5. Manufacturer's detailed instructions for use.

9.2.6. The warning, "Protect From Freezing."

10. COMPLIANCE: In order for consideration to be given to the bid on an item under this specification, the bidder must comply with the following:

10.1. PRODUCT IDENTIFICATION: The make, model number, name of the manufacturer, brand or trade name, etc., as applicable, of the item which the vendor proposes to furnish must be stated as part of the bid.

10.2. EXCEPTIONS: Notwithstanding the above, any exception taken by the bidder to the requirements and conditions of this specification must be stated and described in detail as a part of the bid. If no exceptions or deviations are identified in this manner, the items must be furnished exactly as described herein.

10.3. PROOF: The bidder shall bear the burden of proof of compliance with this specification.

11. PRODUCT INFORMATION: This synthetic floor finish is designed for use in areas of heavy foot traffic. It is exceptionally resistant to heel marking and scuffing, and gives a high gloss without buffing. As a "dry-bright" rather than a "buffable" finish, it should not be subjected to frequent buffing with a floor machine.

However, when the original gloss becomes reduced by wear, it may be restored by occasional spray buffing. Damp mopping with cool, clean tap water, to which may be added a little mild detergent, should usually be sufficient for maintenance.

Metal-corsslined polymer floor finish should be applied only to flooring surfaces which have been thoroughly cleaned and rinsed with fresh water. Certain surfaces should also have been sealed with an appropriate sealer (Example: Floor sealer, Water Emulsion Type, Texas Specification No. 485-54-06, for masonry and porous tile floors.) both the standard (16% solids) and the high-strenght (25% solids) products are suitable for application in a single uniform coat. For use in areas of frequent, heavy traffic, the high-strength grade is especially recommended.

12. ORDERING DATA: When ordering products conforming to this specification the requisitioning agency shall specify the following:

12.1. The number of this specification (485-54-08A).

12.2. The strength required (standard or high strength).

12.3. Number and size of containers required.
