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 maintains good elasticity.
6
🔗Excellent adhesion to most building materials.

Frequently Asked Questions
Q What does "fast curing" mean for this sealant, and why does it matter?
Fast curing means the sealant reaches its stable, cured state in a shorter time compared to standard products. This is especially important in construction environments where weather can change rapidly — a faster cure time minimizes the risk of surface deformation, dust contamination, or rain damage before the sealant fully sets.
Q Is this sealant safe to use on coated glass and metal surfaces?
Yes. This product uses neutral curing chemistry, which means it does not release acetic acid or other corrosive byproducts during curing. It is completely safe for use on coated glass, anodized aluminum, stainless steel, and other sensitive building materials.
Q Can this sealant handle the movement and deformation of a curtain wall system?
Absolutely. The sealant is specifically engineered to accommodate the normal expansion, contraction, and shear deformation that occur in curtain wall systems due to thermal changes, wind loads, and building settlement — all without losing its sealing performance or structural integrity.
Q What temperature range can this sealant withstand after curing?
After full curing, the sealant maintains excellent performance across an extreme temperature range — from as low as -50°C without becoming brittle or cracking, to as high as 150°C without softening or degrading. This makes it suitable for both cold-climate and high-heat applications.
Q How does this sealant perform against UV exposure and outdoor weathering?
This sealant offers excellent resistance to UV radiation, ozone, heat, cold, and moisture — all key factors in long-term outdoor durability. It is designed to resist yellowing, chalking, and degradation even after prolonged sun and weather exposure, making it ideal for exterior façade and curtain wall applications.
Q What types of building materials is this sealant compatible with?
This sealant provides excellent adhesion to a wide range of building materials, including glass, aluminum, steel, concrete, stone, ceramic tile, and most painted or coated surfaces. Its broad compatibility makes it a versatile choice for both new construction and renovation projects.
