Cured sealant is mildew resistant
Dow Corning® 786 Silicone Sealant is a single-component, ready-to-use silicone rubber sealant designed to seal nonporous surfaces around showers, tubs, sinks and plumbing fixtures where conditions of high humidity and temperature extremes exist.The sealant adheres to many nonporous surfaces, such as porcelain, cultured marble, marble, painted areas and glass, without the use of a primer. Dow Corning® 786 Silicone Sealant is compatible with most substrates; however, adhesion and compatibility should be evaluated in each instance prior to use.

IMPORTANT INFORMATION
LIMITATIONS
Dow Corning 786 Silicone Sealant is not recommended for use in the following applications:
- Structural silicone glazing
- Floor joints where physical abuse or abrasion is likely to be encountered
- Prolonged water immersion
- Porous surfaces, such as masonry
- Building materials that might bleed oils or solvents -- materials such as impregnated wood, partially vulcanized rubber gaskets or tapes or adhesives
- Totally confined spaces, because the sealant requires atmospheric moisture for cure
- Surfaces sensitive to corrosion by acetic acid vapors (a byproduct of sealant cure).
