    Raven 155

    Waterborne Epoxy to Reduce Water Transmission

    Product Description

    Raven 155 is a waterborne epoxy used to reduce water vapour transmission and seal green concrete surfaces prior to topcoat application. It is a two-component waterborne epoxy with ultra-low viscosity.

    Use as a penetrating primer/sealer for new and existing concrete and as a polymer additive with high-early strength repair mortars.

    Recommended Uses

    This product is particularly suitable to prevent out-gassing through topcoats and Raven recommends using Raven 155 to prime concrete exhibiting a moisture vapour emission rate greater than 3 lbs/1,000 ft2/24 hours, when tested according to ASTM F 1869.
