BOSS® PU SL is a polyurethane sealant that is one-component and moisture-curing. Once set, it cures into a flexible, durable, and weather-resistant elastomeric sealant that has very good adhesion to most construction and industrial materials. It can accommodate cyclic joint movement of up to 50% of the joint width.
