Product Details

Dowsil® Neutral Plus Silicone – High-Performance Multi-Purpose Sealant

Dowsil® Neutral Plus (formerly Dow Corning) is a professional-grade, one-part neutral cure silicone sealant designed for a wide range of glazing and weatherproofing applications. This 280ml cartridge is the go-to choice for those seeking a non-corrosive, durable seal that adheres to both porous and non-porous surfaces.

Available in Clear, White, and Black, it provides a clean, aesthetic finish while maintaining industrial-strength performance.

Key Features

  • Neutral Cure System: Non-corrosive to metals and sensitive substrates, making it safer for concrete, stone, and masonry compared to acetoxy silicones.
  • Weather & UV Resistance: Highly resistant to ozone, ultra-violet radiation, and temperature extremes; it won’t crack, crumble, or dry out.
  • Excellent Adhesion: Bonds strongly to glass, aluminum, painted surfaces, ceramics, bricks, and most plastics without the need for a primer.
  • Low Odor: Suitable for indoor applications where strong chemical smells are a concern.
  • Flexible & Durable: Maintains its elasticity over a wide temperature range, accommodating joint movement without losing bond integrity.
