Why Choose Dow Dowsil 995 Structural Glazing Silicone Sealant?

The Dow Dowsil 995 is renowned in the construction industry for its ability to form high-strength structural bonds that can withstand extreme environmental conditions. It is specially designed to handle wind loads, thermal expansion, and building movements while maintaining flexibility and adhesion. Its neutral cure formula ensures that it does not corrode metal substrates or compromise glass coatings, making it suitable for both interior and exterior structural glazing projects. Available in black, this sealant provides a sleek, modern finish that enhances the appearance of architectural designs, available in 3 colours.

Key Features of the Dowsil 995 BLACK Trade Box

• Trade Supply: Includes 12 cartridges of high-performance structural glazing silicone, ideal for large projects and multi-site operations.
• Exceptional Bond Strength: Designed for structural glazing applications, providing secure bonding for glass and metal components.
• Low Modulus for Flexibility: Absorbs dynamic joint movement, such as wind loads and temperature-induced expansion.
• Weatherproof and UV Resistant: Withstands prolonged exposure to UV rays, rain, and temperature fluctuations.
• Neutral Cure: Non-corrosive and compatible with aluminium, coated metals, glass, and composite panels.
• Professional Black Finish: Creates sleek, unobtrusive seals, ideal for visible structural joints in modern architecture.
• Multi-Surface Compatibility: Adheres to glass, metal, steel, aluminium, and composite cladding materials.

Application Method:

Install backer rod material or joint filler, setting blocks, spacer shims and tapes, mask areas adjacent to joints to ensure neat sealant lines, a primer is generally not required on non-porous surfaces, but may be necessary for optimal sealing of certain porous surfaces.

1. What are the key features that make Dow Dowsil 995 suitable for structural glazing?
The Dow Dowsil 995 is designed specifically for high-performance structural glazing and bonding. It offers superior tensile strength, enabling it to bear heavy loads, such as glass panels, without failure. Its low-modulus formulation allows it to absorb dynamic forces, including wind loads, vibrations, and thermal expansion, without cracking or losing adhesion. The neutral cure technology prevents corrosion, ensuring compatibility with sensitive materials like glass, aluminium, and steel. Additionally, its weather and UV resistance make it highly durable for exterior applications, including tall building facades and large-scale curtain wall systems.

2. How does this sealant perform in extreme environmental conditions?
Dow Corning Dowsil 995 is engineered to maintain its performance in a wide range of environmental conditions. It has excellent UV stability, preventing degradation from prolonged sun exposure. Its moisture-resistant properties protect against rain and high humidity, while its flexibility ensures it adapts to temperature changes without becoming brittle. This makes it suitable for use in both hot and cold climates, as well as for structures exposed to high winds and thermal shifts.

3. Can this sealant handle dynamic loads, such as wind pressure and building movement?
Yes, Dowsil 995 is designed to handle both static and dynamic loads. Its high elongation and flexibility allow it to absorb and distribute the stress caused by wind pressure, vibrations, and thermal expansion. In high-rise and large facade projects, this capability is crucial for maintaining structural integrity over time. Unlike rigid adhesives, this sealant prevents stress concentration at the joint, reducing the risk of joint failure and cracking in structures exposed to environmental forces.

4. What types of materials can this sealant bond to, and how should surfaces be prepared?
The Dow Dowsil 995 adheres effectively to a wide range of materials, including glass, aluminium, steel, and composite panels. To achieve optimal adhesion, all surfaces must be properly prepared. This involves cleaning the surfaces thoroughly to remove dust, grease, and contaminants. For non-porous materials like glass and metal, a solvent-based cleaner may be used. Allow the surfaces to dry fully before applying the sealant. In some cases, a primer may be necessary to enhance adhesion, particularly on challenging substrates.
