DOWSIL 888 Silicone Joint Sealant is a one-part, self-leveling, low-modulus silicone formulated for sealing concrete expansion joints in roadways, runways, bridges, and pavements. With excellent flexibility and UV resistance, it accommodates thermal movement and delivers durable joint performance in extreme traffic and climate conditions. Designed to bond strongly to concrete without the need for a primer in most cases, it ensures long-term joint protection in high-load environments.
RECOMMENDED USE:
- Sealing transverse contraction and expansion joints.
- Sealing longitudinal, centre line and shoulder joints in Portland cement concrete.
- Suitable for warehouse, highway, airport and bridge joints in which high movement occurs.
- For use in repair or remedial applications where other joint sealing materials have failed.
