Dowsil 895 Questions and Answers:

1. How does Dow Dowsil 895 enhance the safety and stability of structural glazing applications?
The Dow Dowsil 895 is specifically formulated to deliver both high tensile strength and flexibility, crucial for maintaining the stability of structural glazing systems. It forms a robust bond between glass and metal frames, absorbing external forces such as wind loads, thermal expansion, and building movement. This flexibility prevents stress build-up that could lead to cracking or joint failure. Additionally, the sealant's long-lasting durability ensures that the bond maintains its integrity for decades, providing enhanced safety in high-rise and curtain wall applications.

2. Why is the neutral cure formula important in structural applications involving metal and glass?
Neutral cure silicones, such as Dow Dowsil 895, do not release acidic by-products during curing. This prevents corrosion and degradation of sensitive materials like aluminium, steel, and coated glass. In structural applications, where both the bond and the materials must withstand environmental stress, this feature helps extend the lifespan of the seal and prevents long-term material damage. The non-corrosive nature of the sealant ensures that both glass and metal components retain their structural properties over time.

3. Can Dow Corning Dowsil 895 be used in extreme weather conditions, and how does it perform?
Yes, Dow Dowsil 895 is designed to withstand harsh environmental conditions, including extreme temperatures, UV exposure, heavy rain, and wind pressure. Its weatherproof properties prevent degradation caused by prolonged sunlight, ensuring the sealant remains flexible and adhesive even after years of exposure. The sealant also resists shrinkage, cracking, and moisture penetration, making it ideal for outdoor applications, such as high-rise curtain walls and facade cladding, where structural integrity is crucial in varying climates.

4. What are the key differences between Dow Dowsil 895 and standard silicone sealants?
Unlike standard silicone sealants, Dow Dowsil 895 is a high-performance structural glazing sealant designed to provide enhanced adhesion and flexibility under load-bearing conditions. It can handle greater movement and stress without failure, making it suitable for applications where glass and metal frames are structurally bonded. Additionally, its neutral cure formula is tailored to protect sensitive materials from corrosion, while standard silicones may not offer the same level of durability, tensile strength, or long-term performance required in structural applications.

5. How should I prepare surfaces to ensure optimal adhesion with Dow Corning Dowsil 895?
For optimal adhesion, all bonding surfaces should be thoroughly cleaned and dried. Use a solvent-based cleaner or isopropyl alcohol to remove dirt, grease, and other contaminants from non-porous surfaces like glass and metal. Ensure there is no residual moisture, as it can affect adhesion. In cases where the substrate is particularly challenging (e.g., coated metals or rough concrete), applying a primer may be necessary to enhance bond strength. Proper surface preparation ensures that the sealant achieves full adhesion and long-term durability, reducing the risk of future joint failure.
