CRL 95C silicone is a primerless, non-structural glazing and weatherproofing sealant that is capable of taking joint movements of ±50% in a appropriately designed joint. CRL 95C silicone sealant cures to a durable, flexible, weather-resistant silicone rubber when exposed to atmospheric moisture. CRL 95C silicone sealant is designed to tool easily. CRL 95C silicone sealant does not contain plasticizers, UV absorbers or solvents. CRL 95C silicone sealant's physical properties will remain stable over time and in severe weather conditions.CRL 95C silicone sealant's consistency is relatively unchanged over a wide temperature range, (-20 °F to 120°F), which allows this sealant to be applied in any season. CRL 95C silicone sealant has outstanding weatherability properties. CRL 95C silicone sealant is virtually unaffected by normal weathering conditions such as rain, sunlight, snow, sleet, ultraviolet radiation, ozone, atmospheric contamination and acid rain. Properly installed joints formed with CRL 95C silicone sealant can be expected to extend and compress 100% of the installation width with no more than 50% in a single direction without affecting the seal or adhesive bond. CRL 95C silicone sealant is compatible with most laminated glass, reflective coated glass, Low-E Glass, insulating glass units, and acrylic and polycarbonate glazing sheets. 95C silicone sealant, in general, does not require priming. In view of the unpredictability of surface characteristics, it is always recommended that a test sample of sealant be applied on the surface to test adhesion.
