Document record
This one-page data sheet covers Urethane Brush-Grade 524-CA, a high-solids, single-component aliphatic polyurethane flashing material. The sheet is numbered PDS-092123. It states that the product is formulated to be monolithic, flexible and lightweight, and lists conventional commercial and industrial surfaces it can protect, including EPDM, single-ply membranes, concrete, modified bitumen, metal and polyurethane foam.
The technical data lists 76.7% solids by volume, 230% elongation, 2,300 psi tensile strength and 100 KU viscosity. VOC is below 50 g/L, and the weight is 10.49 to 10.89 pounds per gallon. The white product is packed in 3-gallon containers, has a one-year shelf life and is cleaned up with acetone. The sheet also lists reflection of 80% of solar rays.
Application is by heavy brush as received. The sheet permits thinning by up to 10% by volume with acetone if viscosity rises. The substrate must be above 40°F and below 100°F, and more than 5°F above the dew point and rising. The listed dry time is 12 hours at 77°F and 50% relative humidity, and the recommended storage temperature is 75°F.
