Basic Uses TT-S-001543A (COM-NBS) Class A for Silicone Building Sealants
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!
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.
