The Dowsil 785 Acetoxy Silicone in Jasmine is designed for professionals and DIYers needing a reliable, bacteria-resistant sealant for sanitary fittings, kitchens, and clean rooms. Its key benefit is providing strong adhesion to non-porous surfaces while actively inhibiting mold, bacteria, MRSA, E. coli, and Salmonella growth, ensuring a hygienic seal. A potential caveat is its acetoxy cure, which releases acetic acid and may not be suitable for all metal substrates or sensitive environments.

Its primary benefit is being a bacteria and mold resistant silicone sealant, providing hygienic protection for sanitary applications.
It adheres well to many non-porous surfaces including aluminum. However, due to its acetoxy cure releasing acetic acid, it is not recommended for sensitive metals like brass, copper, or lead as it may cause corrosion.
It becomes tack-free in about 1 hour and fully cures over a longer period, depending on bead size and environmental conditions. Avoid water contact until fully cured.
While it offers good adhesion and durability, its primary design is for interior sanitary and kitchen applications. For extensive outdoor exposure, consider sealants specifically formulated for exterior weather resistance.
Acetoxy silicone is a type of silicone sealant that releases acetic acid (vinegar smell) as it cures. This process creates a strong, durable, and waterproof seal.
It can accommodate up to 20% joint movement, meaning the joint can expand or contract by 20% of its original width without compromising the seal.
The Jasmine color is a light, neutral yellow. While it offers a clean look, it is distinct from pure white. White or clear variants of Dowsil 785+ are available if a pure white finish is required.
Ensure the surface is clean, dry, and free from dust, grease, or previous sealant residues. The surface must be non-porous.
Work in smaller sections and smooth the bead immediately after applying. Ensure proper ventilation, but avoid strong drafts directly on the application area.
While designed for durability, prolonged exposure to UV or certain chemicals might affect color. Ensure proper application and curing as per instructions.
While the sealant resists mold, the surrounding area may still be susceptible. Thoroughly clean the area before application and ensure good ventilation after use.
Setup: Ensure surfaces are clean, dry, and free from dust, grease, and old sealant. Cut the cartridge nozzle at an angle to achieve the desired bead size. Use a caulking gun to apply a consistent bead of sealant. Smooth the bead immediately after application using a wet tool or finger. Allow to cure fully before exposing to water or heavy use.
Compatibility: Excellent adhesion to non-porous surfaces like ceramics, porcelain, glass, aluminum, and enamel. *Caution*: Due to the acetic acid released during acetoxy cure, avoid use on sensitive metals (e.g., brass, copper, lead) or where corrosion is a concern. Test on a small, inconspicuous area if unsure about compatibility with specific materials.
Care: Clean any excess uncured sealant immediately with a damp cloth. Once cured, the sealant can be cleaned with mild detergents and water. Avoid abrasive cleaners that could damage the surface or the sealant.
