PSI-601 is a one-part, RTV silicone sealant that cures in the presence of atmospheric moisture to a durable, flexible rubber with excellent adhesion to most non-porous surfaces, including glass, metal, ceramic, porcelain, many plastics, and painted surfaces. PSI-601 may be factory or field applied to form a long-lasting seal resistant to the effects of rain, snow, ultraviolet radiation, ozone, sunlight and temperature extremes.

• Highly flexible over a wide temperature range
• UV and ozone-resistant
• Excellent adhesion and superior durability on most non-porous surfaces
• Capable of compensating for joint movement of ±25% of the original joint geometry
