PSI-275 is a three-part, gun-grade polysulfide sealant that offers a durable, water-resistant seal in joints exposed to many chemicals and/or water immersion. The sealant can be used for sealing vertical, horizontal and sloping joints, especially concrete joints subject to structural movement. PSI-275 cures at ambient temperature to a medium-modulus, flexible rubber.

The sealant adheres to a range of substrates commonly used in construction, such as masonry, metal, concrete, plastics, glass, ceramics and wood.
