Aliphatic Polyaspartic Polyurea Coating

DESCRIPTION

Product #488 is a two component, ultra high solids, aliphatic polyaspartic polyurea designed to provide high gloss, UV stable (non-yellowing) and chemical resistant protection. Product #488 two component, ultra high solids, aliphatic polyaspartic polyurea is a superior, new generation product exhibiting fast cure time and excellent stain resistance.

Product #488 aliphatic polyaspartic polyurea has very low odor and can be applied indoors in occupied areas. Product #488 aliphatic polyaspartic polyurea is generally used as a clear or pigmented high gloss finish  over decorative and industrial flooring systems.

ADVANTAGES

• VOC compliant
• Excellent abrasion resistance
• Fast set times
• Chemical & stain resistant
• Excellent UV resistance
• Low odor-used in occupied areas
• High gloss

CONSIDERATIONS

• Substrate temperature must be a minimum of 50^oF
• Substrate must be free of dirt, waxes, curing agents and other foreign materials
• Do not apply over damp or wet substrates
• Avoid applications on surfaces with active moisture vapor transmission
• Very fast set (short working time)

COMPOSITION

Two Component, Catalyzed Polyaspartic Polymer

APPLICATION

SURFACE PREPARATION

Surface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared as outlined in Epoxy.com's Surface Preparation Guide. Epoxy.com technical service department is pleased to answer any questions.

INSTALLATION

Product #488 aliphatic polyaspartic polyurea is a two component material (2 parts A to 1 part B by Vol.). Add Part B to Part A while mixing, using a slow speed mechanical mixer (Jiffy mixer). Mix until a homogeneous mixture is obtained (approximately 3 minutes). Use care to scrape sides and bottom of container to ensure that no unmixed material remains. Do not whip too much air into the material which may result in pinholes or blisters. Do not mix more material than can be used in 10-15 minutes.

Product #488 aliphatic polyaspartic polyurea will begin to increase in viscosity immediately after mixing and will double in viscosity within 17-20 minutes. Material should be in place at this point.

Immediately after mixing, pour material on floor in a ribbon and spread with a flat trowel or notched squeegee depending on thickness of application. Typical application is 8-12 mils (130-200 sq/gal.). Backroll spread material gently with a short nap mohair roller. Do not over roll and entrap air. Total application time should take no longer than 15 minutes.

Up to 5% solvent (xylene, MEK or similar) may be added at time of mixing to slightly lower viscosity and lengthen pot life.

Product #488 aliphatic polyaspartic polyurea will be tack-free in 2-2 � hours at 70^oF and 50% relative humidity. Allow 4 hours between coats if applying more than one coat. Light pedestrian traffic is possible after 4 hours, 24-48 hours before heavy pedestrian or automotive traffic. Product #488 aliphatic polyaspartic polyurea is highly stain resistant and hot tire resistant after 48 hours.

CLEAN-UP

Clean skin with soap and water. Tools and equipment should be cleaned with xylene or lacquer thinner.

COVERAGE

Product #488 aliphatic polyaspartic polyurea is typically spread at 160 ft²/gallon to yield 8-10 mils. Up to 15 mils is possible in one application but will exhibit a longer set time.

COLOR

Product #488 aliphatic polyaspartic polyurea is available in Clear. Color packs available in Light Grey, Slate Blue, Taupe, Beige, Safety Yellow.
