UT-9800 Two-part Aliphatic Polyester Urethane (Gloss or Matte)

1.- Product Description:

A.- COMPOSITION:

UT-9800 Clear Gloss and UT-9800 Matte represent the next generation of urethane topcoats. They are a blended aliphatic polyester urethane, which is ultraviolet light stable. In addition, they provide high chemical, abrasion and UV resistance and a low VOC of 250 grams per liter or less and they are compliant with Industrial Maintenance Coating Guidelines.

UT-9800 Clear Aliphatic Polyester Urethane Topcoat has a high gloss finish and UT-9800 Matte Aliphatic Polyester Urethane Topcoat has a matte dull finish. Both systems are highly durable, chemical resistant floor topcoat and finish coat designed for use in aircraft hangars, service bays, manufacturing areas, etc. UT-9800 has excellent clean ability and superior long-term appearance.

They conform to all requirements of U.S. General Services Administration Specification A-A-50542 (Coating System: Reflective, Slip Resistant, Chemical-Resistant Urethane for Maintenance Facility Floors).

UT-9800 is VOC compliant, meeting the most stringent guidelines, including the South Coast Air Quality Management Division of Southern California. However the material does emit a solvent odor during installation. This product can be used in both interior and exterior service. UT-9800 possesses excellent resistance to ultraviolet light including freedom from color change or degradation.

B. ADVANTAGES AND LIMITATIONS

ADVANTAGES

1. Excellent gloss, clean ability and abrasion resistance.
2. Resists wide range of service area chemicals.
3. Complies with VOC regulations.
4. Convenient 1 to 1 mix ratio.

MIXING:

Shake well each container, then mix Part A and Part B (1 part A: 1 part B) 1:1 RATIO. Stir the mix thoroughly and let it settle for 10 minutes until all the air bubbles disappear and the solution becomes homogenous.

LIMITATIONS:

1. Substrate must be above 50oF (10oC), dry and free of excessive water vapor transmission with a relative humidity below 85% at time of installation.
2. Moving cracks in concrete may reflect through finish.
3. A waterproofing and crack isolation membrane can be installed prior to system application.
4. Moisture vapor transmission (MVT) in excess of 3.0 lbs./1000 sq/ft/per 24 hr. period per ASTM F1869, may result in delaminating, discoloration or improper curing. Use Triple-S Vapor-Lok 100 vapor control membrane over substrates, which have MVT emissions that exceed these limits. Consult with Triple-S prior to using Vapor-Lok 100 if moisture vapor transmission exceeds 15 lbs/1000 sq/ft/per 24 hr period per ASTM F1869.

2. OVERVIEW OF INSTALLATION STEPS

• Prepare surface by careful and thorough removal of laitance, grease, and foreign matter.
• Apply epoxy primer coat, filling existing cracks or voids in the concrete.
• Spread body coat by squeegee and back roll in two coats to Achieve a uniform thickness.
• Optional: For additional slip resistance broadcast one of the Posi-Tred pre-engineered slip resistant aluminum oxide blended aggregates into the prime coat and topcoat the prime coat, prior to placement of UT-9800.

3. SLIP RESISTANCE AND CLEAN ABILITY

In general the more aggressive the finished surface the greater the coefficient of friction and corresponding slip resistance, the more difficult to clean. The smoother the finished texture the easier the surface is to clean, but there is a loss of slip resistant properties.

4. CLEANING

Cleaning and disinfecting compounds and cleaning techniques can affect the color, gloss, texture and performance of the system. As a precautionary step, Triple-S Chemical recommends that the end-user test their cleaning and disinfecting compounds on a sample or on a small, out of the way finished area, utilizing the intended cleaning technique prior to cleaning the entire surface area. If no deleterious effects are observed, the procedure can be continued. If the cleaning and disinfecting compounds or cleaning techniques damage the system, modification of the cleaning material or techniques will be required. Concrete cleaner #1400 can be used for this purpose.

5. CHEMICAL RESISTANCE

See Triple-S Chemical Resistance Guidelines for chemical resistance of a product or system, as well as the types of test performed:

• ASTM C868 Standard Test Method for Chemical Resistance of Protective Lining.
• ASTM C267 Standard Test Method for Chemical Resistance of Mortars, Grouts, and Monolithic Surfacing and Polymer Concretes.
• ASTM D1308 Standard Test Method for Effect of Household Chemicals on Clear and Pigmented Organic Finishes.

Note: Chemical resistance is a functional test, usually limited to changes in weight or thickness measured in loss or gain and does not evaluate subject aesthetic issues. To determine aesthetic issues, Triple-S Chemical recommends testing the products or system in accordance with intended end use.

6. TESTING:

The technical data contained herein is the result of tests made in independent laboratories using small scale equipment, following generally accepted trade practices. Although this information is believed to be true and accurate, the use of different equipment for testing under dissimilar conditions or the testing of samples produced under dissimilar conditions may develop substantially different results.
