CRL 95C Silicone (SKU: 95CGRY) is a one-part, low-modulus, neutral-cure silicone sealant that cures to a durable, flexible silicone rubber building joint seal. Designed as a weatherproof glazing and curtain wall sealant, it accommodates ±50% joint movement in properly designed joints and provides primerless adhesion in most applications. Typical uses include sealing expansion and control joints in precast concrete panels and metal curtainwalls, non-structural glazing of glass, metal and plastics, and perimeter waterproofing for doors and windows.

CRL 95C bonds watertight to glass, ceramics, plastics, stone, masonry, wood, steel, anodized and mill-finish aluminum, and painted surfaces (in most cases no primer required). It can be applied to clean, dry, frost-free surfaces between -20°F (-29°C) and 130°F (54°C). Cured sealant performs from -40°F (-40°C) up to 350°F (177°C). For certain substrates, Cat. No. S1L2100 primer may be required. CRL 95C is compatible with laminated glass, insulating glass units, and acrylic or polycarbonate glazing sheets; it can be used as a weather seal for IG units produced with a variety of primary sealants.

BASIC USES
Sealing expansion and control joints in precast concrete panels and metal curtainwalls; non-structural glazing of glass, metal and plastic; perimeter and weatherproofing seals for doors, windows and storefronts. In most cases no primer is required — ensure surfaces are properly cleaned and tool the sealant for optimum adhesion. Test compatibility with specialty coatings and polycarbonate where stress cracking may occur.

LIMITATIONS
Not for structural glazing, horizontal decks, patios, driveways, terrace joints subject to abrasion, submerged joints, or exterior/interior sealing below the waterline in marine applications. Do not use in totally confined/air-free spaces or on surfaces that will be painted after application (paint will not stretch with the sealant). Neutral-cure by-products may stress-crack some polycarbonate—test before use. Do not apply to surfaces
