❓ Frequently Asked Questions
Q
What makes JF-303 sealant suitable for curtain wall applications?
JF-303 is engineered to handle the normal expansion and shear deformation of curtain wall systems without performance loss. Its neutral curing formula also ensures it won't corrode metal frames, coated glass, or other sensitive building materials.
Q
What is the temperature resistance range of JF-303 after curing?
After curing, JF-303 maintains excellent elasticity across a wide temperature range. It will not become brittle, harden, or crack at temperatures as low as -50°C, and will not soften or degrade at temperatures as high as 150°C.
Q
Why is fast curing important for a sealant product?
Fast curing significantly reduces the window of exposure to adverse weather conditions during the curing process. This minimizes the risk of surface deformation, contamination, or bonding failure caused by rain, humidity, or temperature fluctuations.
Q
Is JF-303 resistant to UV and ozone exposure?
Yes. JF-303 offers excellent weathering resistance, including outstanding UV resistance and ozone resistance. This makes it ideal for outdoor applications where prolonged sun and environmental exposure are expected.
Q
What building materials is JF-303 compatible with?
JF-303 provides excellent adhesion to most common building materials, including glass, metal, coated surfaces, concrete, and stone. Its neutral curing system ensures no corrosive reaction with sensitive substrates.
Q
How does JF-303 perform in terms of water resistance?
JF-303 exhibits strong water resistance, making it a reliable choice for sealing joints in exterior facades, curtain walls, and other areas exposed to moisture, rain, or high-humidity environments.
