Titebond® 100% Silicone Sealant is a versatile formula that is ideal for both interior and exterior applications. It is an RTV industrial sealant and offers best adhesion to many common construction materials, aluminum, including vinyl, glass and painted surfaces. It also provides a strong, flexible seal that offers best water-resistance. When fully cured, Titebond 100% Silicone Sealant can withstand extreme temperature conditions. The 100% antimicrobial formula will not crack or become brittle with age and resists fading or yellowing. It also extrudes easily in lower temperatures and dries quickly.
