Sikasil WS-290 FPS is a one-component field pigmentable silicone building sealant. Color packs are sold separately and custom colors are available. It is non-sag, neutral cure silicone sealant. Used for sealing expansion and control joints in precast concrete panels and metal curtain walls, weathersealing glass to glass butt joints, weathersealing nonstructural glazing, and sealing EIFS.

Product Description

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.
