DOWSIL™ 758 Silicone Weather Barrier Sealant

A one part, neutral cure silicone elastomeric sealant, designed for primerless adhesion to challenging, low surface energy, air & weather barriers, window flashings and other fenestration materials.

Dow DOWSIL™ Allguard

Dow DOWSIL™ is an elastomeric coating for exterior architectural applications. The product has a unique combination of UV stability and breathability inherent to silicone polymers, which allows moisture to escape from the building and prevents mold issues in most situations. This combination enables us to provide the best architectural paint and coating warranty in the industry: a 10-year non-pro-rated warranty for material and labour.

Dow DOWSIL™ Allguard protects the underlying substrate from weathering and will not peel or crack. It is available in thousands of colours, custom-tinted in our warehouse, and has a proven 25-year track record in Canada.

DOWSIL™ 982 Silicone Insulating Glass Sealant

A two-part silicone sealant designed for use as a secondary sealant in a dual-sealed insulating glass unit, as well as in an insulating glass unit that will be structurally glazed. The product cures to a durable, high-modulus, flexible silicone seal that is chemically stable and creates a weathertight bond. It has excellent unprimed adhesion to glass and metal substrates, such as galvanized steel and aluminum.

DOWSIL™ 983 Structural Glazing Sealant

Designed for specialized use where dual structural and weatherseal applications are desired for factory glazing and curtainwall production. Once cured, this structural sealant forms a durable, flexible, watertight bond that can be warranted for 20 years and used in ±25% movement weatherseal applications. It has excellent unprimed adhesion to glass, alodine, and anodized aluminum, although DOWSIL™ Primer-C OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications.

DOWSIL™ 3363 Insulating Glass Sealant

A high strength secondary two-part silicone sealant specifically designed for high strength applications, where conventional sealants with lower strength would lead to increased joint sizes. It enables economical joint sizes in highly demanding insulating glass applications such as: high wind in tall buildings, hurricane loads, cold-bent glass or high impact loads such as bomb blast. Smaller joint dimensions can be filled faster and therefore lead to productivity enhancements.
