Sikasil WS-290 FPS is a field pigmentable, low to no bleed, low modulus, one”“component plus color pack, non-sag, elastomeric, neutral cure silicone sealant.
Sikasil WS-290 FPS performs exceptionally well under dynamic conditions due to its ultra-low modulus of elasticity, high extension/compression, recovery properties and strong adhesion to most building materials. Sikasil WS-290 FPS accommodates long-term joint 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-19-.13-M87, AAMA 808.3. Where to Use
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
