PRODUCT DESCRIPTION

Unveil the unmatched excellence of HM-SS5549, a silicone weather-resistant adhesive tailored for construction. This one-component marvel, with its neutral curing, low modulus, and high elasticity, offers superior flexibility and displacement capabilities. Its impeccable adhesion to various powder-coated metals sets a new standard. Enhanced by its thixotropic nature, this adhesive remains steadfast and sag-free when applied to building joints, making it the perfect choice for non-structural bonding, weather resistance, and waterproof sealing of curtain walls. Its versatility shines through, thriving in a wide range of climatic conditions while ensuring excellent adhesion and compatibility with most substrates sans primer. Post-curing, it boasts anti-aging, UV resistance, and resilience against extreme temperatures ranging from -50°C to 150°C. Embrace its low modulus prowess, designed to accommodate interface expansion and displacement up to ± 25%, making it an ideal solution for diverse bonding and sealing applications.

FEATURES

1. Exceptional anti-aging properties

2. Robust defense against ultraviolet radiation

3. Resilience to extreme temperature variations (-50°C to 150°C)

4. Low modulus for sustained performance

 

APPLICATION

1. Ideal for sealing and caulking in glass curtain walls, aluminum panel curtain walls, and door and window installations.

2. Perfect for non-structural adhesive assembly in various curtain walls.

3. Sealing and caulking between diverse metals and aluminum alloy doors, windows, and walls.
4. Excellent for use on glass, coated glass, tiles, masonry, concrete, etc.
5. Suitable for wood that does not seep oil, ensuring durability.

 

RESTRICTIONS

APPLICATION TEMPERATURE: Maintain between +5ºC to +45ºC

1. Not designed for structural assembly applications.

2. Avoid using on surfaces that emit plasticizers or solvents, as this could lead to permanent sealant damage.
