CRL 95CWHT White 95C Silicone Sealant for Building Applications

CRL 95CWHT White 95C Silicone Sealant for Building Applications

C.R. Laurence 95CWHT White 95C Silicone Building Sealant is a top-tier, one-part, low modulus sealant that delivers exceptional performance in various construction applications. With its neutral cure formulation, this sealant cures into a durable and flexible silicone rubber, capable of accommodating ±50% joint movement-an ideal choice for sealing expansion and control joints in precast concrete panels and metal curtain walls. This versatile sealant forms a watertight bond with an extensive range of building materials, including glass, ceramics, plastics, and metals. Its excellent primerless adhesion means you can efficiently seal without extensive prep work. Designed to be user-friendly, it offers long tooling time and performs well in temperatures ranging from -20°F to 130°F, making it suitable for year-round applications. The CRL 95C is AAMA approved and meets rigorous standards, including ASTM C-920, ensuring compliance with industry specifications. With a 20-year limited warranty, this product promises longevity and reliability. Available in six colors, including custom color options, it allows for aesthetic flexibility in any project. Whether you're focused on waterproofing or non-structural glazing, the C.R. Laurence 95CWHT 95C Silicone Building Sealant is your go-to solution for professional-grade sealing needs.

CRL 95C Silicone is a one part, low modulus, neutral cure formulation that cures to a durable and flexible silicone rubber building joint seal. It can accommodate ±50 percent joint movement in properly designed joints. It is designed for sealing expansion and control joints in precast concrete panels and metal curtain walls; non-structural glazing of glass, metal and plastic, as well as waterproofing applications, including perimeter sealing of doors and windows.


CRL 95C forms a durable, flexible, watertight bond with most building materials in any combination of glass, ceramics, plastics, stone, masonry, wood, steel, anodized and mill-finished aluminum, and painted surfaces. CRL 95C can be applied at outdoor temperatures as low as -20°F (-29°C), provided that surfaces are clean, dry, and frost-free, or on surfaces as high as 130°F (54.4°C). Cured sealant will perform at cold temperatures down to -40°F (-40°C), or at high temperatures up to 350°F (177°C).

BASIC USES
It is designed for sealing expansion and control joints in precast concrete panels and metal curtainwalls; non-structural glazing of glass, metal, and plastic, as well as waterproofing applications, including perimeter sealing of doors and windows. CRL 95C forms a durable, flexible watertight bond with most building materials in any combination of glass, ceramics, plastics, stone, masonry, wood, steel, anodized and mill-finished aluminum, and painted surfaces. In most cases no primer is required. All surfaces must be properly cleaned and the sealant tooled for good adhesion. Cat. No. S1L2100 Primer may be required for these and other substrates as well. CRL 95C is compatible with all laminated glass, insulating glass units, and acrylic or polycarbonate glazing sheets. CRL 95C can be used as a weather seal for insulating glass units produced with any type of sealant, including two-part silicones, polysulfides, polyurethanes, and butyls. CRL 95C can be applied at outdoor temperatures as low as -20°F (-29°C), provided that surfaces are clean, dry and frost-free, or on surfaces as high as 130°F (54°C). Cured sealant will perform at cold temperatures down to -40°F (-40°C) or at high temperatures up to 350°F (177°C).

LIMITATIONS
CRL 95C should not be used for structural glazing; sealing horizontal decks, patios, driveways or terrace joints where abrasion or physical abuse is encountered; sealing submerged joints; or for exterior or interior sealing below the waterline in marine applications. Do not use CRL 95C in totally confined or air-free spaces, or in designs that will be painted after application of the sealant. Paint film does not stretch with extension of the sealant, and adhesion of paint to the sealant is not adequate. The sealant should be applied after painting is completed. Neutral cure sealant curing by-products may cause stress cracking or surface crazing of polycarbonate sheet under certain conditions. Test application before use. Check cartridge label and Specification Data Sheet for additional limitations.

Product Warning:

CRL 95C should not be used for structural glazing; sealing horizontal decks, patios, driveways or terrace joints where abrasion or physical abuse is encountered; sealing submerged joints; or for exterior or interior sealing below the waterline in marine applications. Do not use CRL 95C in totally confined or air-free spaces, or in designs that will be painted after application of the sealant. Paint film does not stretch with extension of the sealant, and adhesion of paint to the sealant is not adequate. The sealant should be applied after painting is completed. Do not apply to surfaces with special protective or cosmetic coatings without prior consultation of the manufacturer. Neutral cure sealant cure byproducts may cause stress cracking or surface crazing of polycarbonate sheet under certain conditions. Test in application before use. Do not apply to surfaces in direct contact with food. Check cartridge label and Specification Data Sheet for additional limitations.
