1
Fast curing, which can greatly reduce the adverse effects of bad weather on the surface of the sealant during curing (such as surface deformation).
2
Neutral curing, non-corrosive to metal, coated glass and other building materials.
3
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.
4
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.
5
Excellent adhesion to most building materials.
Frequently Asked Questions
Q How fast does JF-303 sealant cure, and why does it matter?
JF-303 features a fast curing formula that significantly minimizes exposure time to unfavorable weather conditions during the curing process. This helps prevent surface deformation and ensures a clean, reliable finish even in variable climates.
Q Is JF-303 safe to use on coated glass and metal surfaces?
Yes. JF-303 uses a neutral curing system, which means it produces no acidic or alkaline by-products during curing. It is completely non-corrosive to metals, coated glass, and other common building materials.
Q Can JF-303 withstand the movement and deformation of curtain wall systems?
Absolutely. JF-303 is specifically engineered to accommodate the normal expansion and shear deformation of curtain wall structures. Its performance remains stable under these conditions, ensuring long-term structural integrity.
Q What temperature range can JF-303 handle after curing?
After curing, JF-303 maintains excellent elasticity across an extreme temperature range. It remains flexible and crack-free at temperatures as low as -50°C and does not soften or degrade at temperatures up to 150°C.
Q How does JF-303 perform against UV, ozone, and outdoor weathering?
JF-303 offers outstanding resistance to UV radiation, ozone exposure, and general outdoor weathering. It is also highly resistant to heat, cold, and moisture, making it an ideal choice for long-term exterior applications.
Q What types of building materials does JF-303 bond well with?
JF-303 provides excellent adhesion to the majority of building materials commonly used in construction, including glass, aluminum, stone, concrete, and various coated surfaces, reducing the need for additional primers in most applications.
