PSI-803 is the polyurethane of choice for dynamic movement. Its unique oxygen cure is not affected by atmospheric moisture, making it ideal for applications in very dry and/or very humid climates. It won’t “blow” or bubble in humid conditions or on damp surfaces. PSI-803 bonds to concrete, masonry, ceramics, glass, wood, metal, PVC and many plastics and cures to a flexible rubber with extraordinary adhesion and cohesion.
