XtraBond®450FS – Fast Set Neutral Cure Silicone Sealant
XtraBond®450FS is a one component, non-sag, permanently flexible, fast set neutral cure silicone sealant. The product is engineered to deliver excellent adhesion to vinyl, glass, aluminum, wood, sheet metal and most common building materials – without the need of a primer. The product is an ideal fit for applications where there is a lack of moisture that would aid the curing process.
XtraBond®450FS cures rapidly when exposed to atmospheric moisture to form a durable tight bond. The product’s design is ideal for back bedding and glazing applications – as well as other exterior applications. It’s the preferred product by users, because it doesn’t leave the odors associated with other silicones.

Material is to be stored under controlled dry environment (below 75° F). Use within 12 months from date of manufacture. For best results, keep material in tightly closed containers when not in use. Do not freeze.
