PRODUCT DESCRIPTION

Introducing HM-SS5549, an epitome of advanced silicone weather-resistant adhesive technology tailored for modern construction needs. This one-component, neutral curing marvel is designed with exceptionally low modulus and high elasticity silicone rubber, offering unparalleled elasticity and displacement deformation capabilities. It's perfectly tailored to adhere seamlessly to a variety of powder-coated metals. With superb thixotropic properties, this adhesive stays put, resisting sagging in building joints, making it the ideal choice for non-structural bonding solutions. Its superior weather resistance and waterproof sealing are perfect for curtain walls, and its adaptability to a broad spectrum of climatic temperatures ensures reliability. You can count on its excellent adhesion and surface compatibility across most substrates, all without the necessity of a primer. Post-curing, it stands strong against aging, ultraviolet rays, and extreme temperatures from -50 to 150°C. Its low modulus performance allows it to accommodate an impressive ± 25% interface expansion and displacement. This versatile adhesive is your go-to for a wide range of bonding and sealing applications.

FEATURES

1. Exceptional anti-aging properties

2. Superior defense against UV radiation

3. Reliability in extreme temperature fluctuations (-50-150°C)

4. Exemplary low modulus performance for flexibility

 

APPLICATION

1. Ideal for sealing and caulking glass curtain walls, aluminum-plastic panel curtain walls, and doors and windows.

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

3. Excellent for sealing and caulking between metal and aluminum alloy doors, windows, and walls.
4. Suitable for glass, coated glass, tiles, masonry, concrete, etc.
5. Use with wood that is free from oil seepage.

 

RESTRICTIONS

APPLICATION TEMPERATURE: +5ºC to +45ºC

1. Not suitable for structural assembly applications.

2. Avoid using on surfaces that release plasticizer or solvent, as it may permanently damage the sealant.

3. Do not use in completely sealed spaces, as it requires water vapor to fully cure.

4. Not advisable for prolonged water immersion.
5. Avoid use on structural surfaces in direct contact with food.
6. Not recommended for medical use.
