CRL WCS5 Water Clear Silicone Sealant – 5 Fluid Ounce Cartridge

CRL Water Clear Silicone Sealant is an optically clear acetic cure, 100% silicone sealant that cures in the presence of atmospheric moisture to produce a durable and flexible silicone rubber. Its unique weatherability enables it to retain its original properties, even after years of exposure.
Basic Uses
Water Clear Silicone Sealant is intended for building construction applications, and is particularly effective for glazing butt and lap shear joints and sealing curtainwall projections and other glass, plastic, and metal assemblies. Its exceptional clarity makes it the ideal sealant to use in frameless shower enclosures. It is also appropriate for general construction and industrial applications. Water Clear Silicone is packaged in two sizes of heavy plastic cartridges that feature removable, reusable, resealable screw-on nozzles with a screw-on cap for convenience and product savings. Water Clear Silicone cures quickly with a tack-free time of 10 minutes. It adheres to clean metal, glass, most types of wood, silicone resin, ceramic, natural and synthetic fiber, and most painted surfaces. For single use applications you’ll find the five fluid ounce size meets your needs exactly!
Important Note
Exceptional clarity of product will not hide application or tooling errors. A small amount of bubbles may form during the curing process of the sealant, so considerations should be made up front regarding standards of appearance and subsequent repairs (e.g., limited to sight lines). Not recommended for use in the following applications: Glazing or edge sealing of insulating glass; copper, brass, magnesium, zinc, galvanized surfaces.
NOTE: Water Clear Silicone is not mildew resistant. Check cartridge label and Specification Data Sheet for additional limitations.
