Sikasil WS-290 FPS Silicone
- – One-component ready to use – Excellent adhesion, bonds to many substrates without priming – Fast Cure – Move assembled or sealed parts quickly – Superior gunning & tooling – Contains anti-microbial additive for mold resistance. – Resistant to UV, ozone, and temperature extremes
Sikasil WS-290 is a one-part, neutral-curing, ultra low modulus, low to no bleed silicone sealant that cures to a durable, flexible building sealant Sikasil WS-290 performs exceptionally well under dynamic conditions due to its ultra-low modulus, high extension/compression, recovery properties and strong adhesion to most building materials. Sikasil WS-290 accommodates long-term movement of +100–50 % in properly designed joints and is particularly well suited for use in Exterior Insulation Finish Systems (EIFS). Meets the requirements of ASTM C-920, Type S, Grade NS, Class 100/50, Use NT, M, G, A, O; TT-S-00230C, Type II, Class A; TT-S-001543A, Class A; CAN/CGSB-1 9.1 3- M87, AAMA 808.3.
USES:
- Sealing expansion and control joints in precast concrete panels and metal curtain walls.
- As a weatherseal in glass to glass butt joint glazing. As a weatherseal in nonstructural glazing applications, including cap, toe and heel beads.
- Exterior Insulation Finish Systems (EIFS) and numerous other areas requiring a high-performance sealant.
