DOWSIL™ Products

DOWSIL™ 888 Silicone Joint Sealant are designed for use in roadway and airport joints calling for a tough sealant that can withstand excessive horizontal and vertical movement, has good weatherability and is easy to install with a short downtime and long service life one-part silicone. These sealants cure upon exposure to moisture in the air to form a permanently flexible, low- to ultralow-modulus, high-elongation silicone rubber seal.

A one-part, cold-applied, easy-to-use, self-leveling silicon material that cures to an ultra-low-modulus silicone rubber upon exposure to atmospheric moisture. The cured silicone rubber remains flexible over the entire temperature range expected in pavement applications.

DOWSIL™ 902 RCS Joint Sealant is a rapid-cure, self-levelling, two-part silicone rubber sealant designed to seal expansion joints primarily intended for use in expansion joints found on bridges that vary in width from 25 to 76 mm at the time of sealing.

DOWSIL™ 1200 OS Primer is used to improve adhesion and accelerate adhesion build-up of silicone sealants to various substrates. This moisture curing primer is supplied as a dilute solution of reactive materials in low viscosity siloxane
