Frequently Asked Questions

1. What are the benefits of the sausage foil packaging over standard cartridges?
The 600ml sausage foil contains a higher volume of sealant, which reduces the need for frequent reloading, especially on large projects. This not only improves efficiency but also reduces packaging waste. Sausage foils are also easier to dispose of, making them more environmentally friendly than rigid cartridges.

2. Is this silicone suitable for use in high-visibility areas?
Yes, the Dow Dowsil 791 Black Silicone Sealant is designed to provide a professional, sleek finish, making it ideal for visible applications such as window and door frames, cladding joints, and curtain walls. The black colour enhances the appearance of joints, particularly in modern architectural projects where aesthetics are important.

3. How does the low-modulus formula benefit structural sealing applications?
The low-modulus formula allows the sealant to flex and absorb joint movement without cracking or losing adhesion. This is crucial for structural joints, which are subject to expansion and contraction due to temperature changes, vibrations, and building shifts. The flexibility ensures the sealant maintains a strong bond over time, enhancing durability and performance.

4. Can this sealant handle harsh environmental conditions?
Yes, Dow Dowsil 791 is engineered to withstand extreme weather, including UV exposure, heavy rain, and temperature fluctuations. Its weatherproof properties prevent discoloration, cracking, and degradation, making it suitable for both exterior and interior applications.

5. What substrates can this sealant bond to?
This silicone sealant bonds effectively to a wide range of materials, including glass, aluminium, steel, concrete, brick, and various plastics. For best results, surfaces should be clean, dry, and free of contaminants. In some cases, a primer may be required for porous substrates to enhance adhesion.
