High Performance Silicone Structural Sealant from China Suppliers - Durable, Fast-Curing, Weather-Resistant Sealant Factory
Fast curing, which can greatly reduce the adverse effects of bad weather on the surface of the sealant during curing (such as surface deformation).
Neutral curing, non-corrosive to metal, coated glass and other building materials.
For the normal expansion and shear deformation of the curtain wall, this product can keep the performance unchanged. Excellent weathering resistance, heat and cold resistance, UV resistance, ozone resistance and water resistance.
Excellent high and low temperature resistance. After curing, it will not be brittle, hardened or cracked at -50°C, and will not soften or degrade at 150°C, and maintain good elasticity.
Excellent adhesion to most building materials.
Frequently Asked Questions
What are the key advantages of JF-303 silicone sealant?
JF-303 features fast curing, neutral curing (non-corrosive properties), excellent adhesion to most building materials, and superior resistance to weathering, UV, ozone, water, and extreme temperatures.
How does the fast-curing feature benefit construction projects?
The fast-curing capability minimizes the adverse impacts of bad weather conditions on the sealant's surface during the curing process, preventing issues like surface deformation.
Is JF-303 safe to use on metals and coated glass?
Yes, JF-303 is a neutral curing sealant. It is entirely non-corrosive to metals, coated glass, and other sensitive building materials.
What temperature range can JF-303 withstand after curing?
Once fully cured, JF-303 maintains excellent elasticity and will not become brittle, hardened, or cracked at -50°C, nor will it soften or degrade at temperatures up to 150°C.
Can JF-303 handle structural movement in curtain walls?
Yes. JF-303 is designed to accommodate normal expansion and shear deformation in curtain walls while maintaining its high sealing performance and elasticity.
