HILKEM 3624 silicone structural sealant is a one-component, high-performance, neutral curing adhesive. It has excellent bonding ability to the surfaces of most materials such as aluminum alloy, stainless steel, microcrystalline glass and ABS+PC. It is weather-resistant, excellent resistant to high and low temperatures, and it has a fast curing speed.
Characteristics
Single-component, easy to use:
It has good extrudability and thixotropy within the temperature range of 4℃ to 40℃ , and it can be directly applied by extruding with the glue gun.
Neutral curing , widely applied:
It has no corrosive effect on building materials such as metals and coated glass.
Excellent displacement capacity:
The displacement capacity reaches ±50%. This product can maintain its performance unchanged during the normal expansion, contraction and shear deformation of the subway platform screen door, and it plays an effective sealing role.
Excellent weather resistance:
Aging resistant, UV resistant, ozone resistant, water resistant.
Excellent resistance to high and low temperatures:
After curing, it will not become brittle, harden or crack at a low temperature of -40℃ , nor will it soften or degrade at a high temperature of 150℃ , it always maintaining good
elasticity.
Excellent adhesion
After curing, it forms a strong bond with most building materials without the need for primer.
Good compatibility:
It has good compatibility with other neutral silicone sealants.
