TREMPRO® 640 and TREMPRO® 642 are one-part liquid polyurethane coatings for industrial use. Available in aluminum color.
Most of the sealants have a 12-month shelf life based on the manufacturing date and batch numbers from the tubes or cases.
Tremco recommends that our sealants be applied at substrate temperatures of 40°F (5°C) and rising to 120°F (49°C).
