Description
Sikasil WS-290 is a one-part, neutral-curing, ultra low-modulus 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.
