The sheet gives a weight of 10.77 pounds per gallon, a flash point of 93°F, a Shore A hardness of 85 and a permeability of 0.9 perms. Water absorption is below 2%. The white product has a service temperature range of -50°F to 200°F and a shelf life of one year. Cleanup is with acetone, and the packaging is 5-gallon.
For application, the sheet gives a minimum application temperature of 40°F and states that successive or top coats must be applied within 48 hours of the base or intermediate coats.
