TREMPRO® 644 High Temperature Silicone Sealant is a one-part, ready-to-use silicone sealant. It has a paste-like consistency and cures to silicone rubber at room temperature.
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).
