High-Solids, Two-Component, Water-Based Aliphatic Polyurethane

APF Polyurethane 501 is a high-solids, two-component, water-based aliphatic polyurethane that delivers performance properties equal to conventional solvent-based catalyzed urethanes, without the associated health and environmental concerns. It is VOC compliant in California, providing substantial improvements over first-generation catalyzed water-based polyurethanes. These improvements include higher film build capabilities, better chemical resistance, and resistance to hot tire staining, making it an ideal choice for high-performance coatings.

Advantages:

• Resistant to fuels and many chemicals
• Provides a hard, high-gloss, and easily cleaned surface
• Graffiti-resistant when used as a wall surface

Mixing Instructions:

• Mix only the amount of material that can be used within a 3-hour period at 77F (25C). Higher temperatures will reduce the working time, so smaller batches should be mixed in hot weather.
• Premix Part A before adding Part B. The correct mixing ratio is 2 parts of Part A to 1 part of Part B.
• Slowly add Part B to Part A while mechanically agitating with a slow-speed drill for 2 full minutes until completely homogenized. Material cannot be properly mixed by hand, so a small squirrel cage mixer should be used for small batches.

Application Instructions:

• Apply at 200-350 sq. ft. per gallon by brush, roller, or airless sprayer.
• Avoid puddling or accumulation in joint areas.
• Applications exceeding 200 sq. ft. per gallon may create bubbles in the cured coating.
• For multiple coats, if the material has cured for more than 24 hours, de-gloss with a black ScotchBrite janitorial abrasive pad or fine sanding screen.

Shelf Life:

• One year from the date of manufacture in the original unopened container.
• Store in a cool, dry place between 50F and 85F (10C 30C).
• Do not allow the material to freeze.
