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.
Frequently Asked Questions
Q How fast does JF402 sealant cure, and why does it matter?
JF402 features a fast curing formula that minimizes exposure time during the curing process. This significantly reduces the risk of surface deformation or damage caused by adverse weather conditions such as rain, dust, or temperature fluctuations.
Q Is JF402 safe to use on coated glass and metal surfaces?
Yes. JF402 uses a neutral curing system, which means it does not release acetic acid or other corrosive byproducts. It is completely safe for use on metal frames, coated glass, anodized aluminum, and a wide range of other sensitive building materials.
Q Can JF402 handle the movement and deformation of curtain wall systems?
Absolutely. JF402 is specifically engineered to accommodate the normal expansion, contraction, and shear deformation that occur in curtain wall systems. Its elastic properties ensure consistent performance even under repeated structural movement.
Q What is the temperature resistance range of JF402?
JF402 offers outstanding temperature resistance. Once cured, it remains flexible and intact at temperatures as low as -50°C without becoming brittle or cracking, and maintains its structural integrity at temperatures up to 150°C without softening or degrading.
Q How does JF402 perform against UV exposure and outdoor weathering?
JF402 provides excellent resistance to UV radiation, ozone, moisture, and extreme weather conditions. This makes it an ideal choice for exterior curtain wall and facade applications where long-term durability and color stability are critical.
Q What types of building materials is JF402 compatible with?
JF402 demonstrates excellent adhesion to most common building materials, including glass, aluminum, steel, stone, concrete, and various coated or treated surfaces. Its broad compatibility makes it a versatile solution for a wide range of construction and glazing applications.
