TOSSEAL 1000 MS is a one-component, modified silicone (MS) polymer-based sealant designed for weathersealing and joint sealing across a wide range of substrates.

TOSSEAL 1000 MS Sealant is designed to support facade and glazing applications where consistent joint performance and finish compatibility are key. Its formulation enables application without a primer on many substrates and offers strong weather resistance without affecting adjacent materials such as natural stone or painted finishes.

The sealant is low in volatile components and can be applied without special ventilation requirements. It is compatible with many common construction finishes and is often selected for projects where a low-gloss finish and minimal substrate staining are important.

Performance

Formulation Attributes

  • Solvent-, silicone-, and isocyanate-free – No added materials that may interfere with sensitive surfaces
  • Neutral cure – Low odor and non-corrosive
  • Paintable when cured – Can be overcoated with many common architectural paints

Application Flexibility

  • Primerless adhesion – Bonds to a range of materials including concrete, aluminum, uPVC, and coated metals
  • Non-staining on porous or decorative surfaces – Reduces risk of visual change on masonry, ACP, or marble
  • Low sag – Suitable for vertical and overhead applications

Environmental Resistance

  • Withstands common weather conditions – Maintains flexibility through seasonal temperature changes
  • UV- and moisture-tolerant – Cured sealant maintains performance when exposed to sunlight and humidity
