About this product
A one part, neutral cure silicone sealant, designed for adhering to low energy surfaces common in sheet or peel and stick weather resistant barriers. Primerless adhesion to LDPE, anodized aluminum, vinyl, powder coated aluminum, Kynar® coated aluminum. It easily extrudes and cures at room temperature by reaction with moisture in the air to form a durable, flexible rubber seal. This medium modulus sealant is specially designed for the weathersealing of weather resistant barriers where low movement is anticipated, such as window and door frames and wall penetrations.
