CRL 95C Silicone Building Sealant Approved for the
Florida Hurricane Impact Glazing Code
Los Angeles-based C.R. Laurence Co. Inc. (CRL), a supplier to the
glazing, architectural, construction, industrial, and automotive
industries, has announced that its CRL 95C silicone building sealant
was recently approved for the Florida Hurricane Impact Glazing Code
and recommended as an installation sealant.
Gary Byrum, CRL sealants product manager, explains that in order
to meet the stringent requirements of impact glazing, window manufacturers
successfully tested 95C Silicone by using their own systems.
"Each window manufacturer must test for use in their systems, and
have the results independently verified," Byrum states. "In addition,
CRL's 95C Silicone Building Sealant is an AAMA verified component
under AAMA 802.3-92 (type I and II), 805.2-94 (Group C), and 808.3-92.
CRL 95C is a one-part, neutral cure silicone that the company says
cures to a durable and flexible silicone rubber building joint seal.
According to CRL, CRL95C can accommodate plus or minus 50 percent
joint movement in properly designed joints. It is applied with conventional
cold-applied pumping equipment and is available in packaging options
including, standard 10.3 fluid ounce (305 ml) cartridges, two-gallon
(7.5 liter) pails, 4.5 gallon (17 liter) pails or 52 gallon (197
liter) drums. It is available in five standard colors; black, dark
bronze, gray, limestone, and precast white. Custom colors are also
available upon request.
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.
CRL 95C is also compatible with all laminated glass, insulating
glass units, and acrylic or polycarbonate glazing sheets. It can
be used as a weather seal for insulating glass units produced with
any type of sealant, including two-part silicones, polysulfides,
polyurethane, and butyls.
