CRL Clear 33S Silicone Sealant - 33SC
Our most popular sealant! CRL 33S Silicone is a high quality sealant that delivers the performance you demand at a competitive price. It is a one component, room temperature curing, acetic cure, 100% silicone elastomer that does not require the addition of activators, stabilizers, or catalysts to achieve optimum performance. 33S Silicone is especially designed for joining and sealing most non-porous building materials including a variety of structural materials: glass, aluminum, metal alloys, stainless steel, wood and plastics. It has a wide operating temperature range of -80 to 400 degrees Fahrenheit (-62 to 204 degrees Celsius), and can be applied at outdoor temperatures as low as -35 to 140 degrees Fahrenheit (-37 to 60 degrees Celsius). 33S exhibits strong physical properties: 350 psi Tensile Strength; 120 psi Lap Shear at 1/8 inch (3 millimeter) thickness and Tear Strength of 25 ppi. It will seal curtainwall joints, steel and aluminum windows, and skylights. Indoor uses include bathtubs, showers and sanitary installations (Mildew Resistant Clear, White, Translucent White and Tan contain a fungicide for cured beads that are mildew resistant).
