Product Description

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.
4
Excellent weathering resistance, heat and cold resistance, UV resistance, ozone resistance and water resistance.
5
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.
6
Excellent adhesion to most building materials.
JF402
Frequently Asked Questions
What makes JF402 sealant suitable for curtain wall applications?
JF402 is specifically designed for curtain wall applications due to its ability to withstand normal expansion and shear deformation without any change in performance. Its excellent weathering resistance, UV resistance, and wide temperature tolerance (-50°C to 150°C) make it highly reliable for long-term curtain wall use.
Is JF402 safe to use on coated glass and metal surfaces?
Yes. JF402 uses a neutral curing system, which means it releases no corrosive by-products during the curing process. It is completely safe for use on coated glass, metals, and other sensitive building materials, preventing any surface damage or staining.
How does JF402 perform in extreme temperature conditions?
JF402 offers outstanding high and low temperature resistance. Once cured, it remains flexible and intact at temperatures as low as -50°C without becoming brittle or cracking, and at temperatures as high as 150°C without softening or degrading, ensuring consistent elasticity across a wide thermal range.
Can JF402 be applied in adverse weather conditions?
Thanks to its fast curing formulation, JF402 significantly minimizes the risk of surface deformation or other issues caused by unfavorable weather during the curing stage. This makes it a practical and reliable choice for outdoor construction projects where weather conditions may be unpredictable.
What types of building materials is JF402 compatible with?
JF402 demonstrates excellent adhesion to most common building materials, including glass, metal, stone, concrete, and various coated surfaces. Its broad compatibility makes it a versatile sealing solution for a wide range of construction and architectural applications.
Does JF402 offer long-term durability against UV and ozone exposure?
Yes. JF402 is formulated with excellent resistance to UV radiation, ozone, and weathering. This ensures that the sealant maintains its structural integrity, flexibility, and appearance over an extended service life, even when exposed to harsh outdoor environmental conditions.
