TremPro® 651 is formulated from a blend of butyl rubber and polyisobutylene to form an economical, flexible sealant.
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).
