What Is Dow Corning 786 Silicone Sealant Used For?

Dow Corning 786 is a single-component, ready-to-use silicone rubber sealant formulated for nonporous surfaces. It is designed for applications where the seal is exposed to prolonged humidity, moisture, steam, and temperature variations.

Typical applications include:

• Sealing around showers and tub enclosures

• Sealing around sinks and bathroom fixtures

• Sealing around plumbing fixtures

• Waterproofing suitable sink applications

• Sealing around whirlpools and similar fixtures

• Ceramic tile grouting

• Other suitable nonporous surfaces requiring a flexible silicone seal

Why Use a Silicone Sealant Designed for High-Moisture Areas?

Areas exposed to water, humidity, and steam require a sealant that can maintain its flexibility and sealing performance over time. Dow Corning 786 is formulated to remain permanently flexible while resisting moisture, free steam, mildew, staining, spotting, and colour changes.

Using an appropriate sealant helps create a consistent barrier around joints and seams, reducing the potential for moisture to penetrate through properly prepared and sealed nonporous surfaces.
