Two parts polyurethane sealant for expansion joint
PENNBOND
two parts polyurethane sealant for expansion joint can form into an elastic sealing compount after fully cured. It also has good chemical medium resistance. Its perfect elongation and physical performance make it an ideal choice for all types of expansion/control joint.
Advantages
- Two-component, room temperature cured, high flexibility, high modulus, high-performance structural silicone sealant. Achieving excellent bonding and sealing performance without primer, suitable to most construction materials, such as in the insulating glass, stones, aluminum or other metal constructions.
- Achieving excellent bonding and sealing performance without primer, suitable apply in most of the construction materials, has good extensibility, water-proofing function, especially for the insulating glass second barrier.
- After the product cured to form a cold, heat, corrosion-free airframe, excellent weather resistance, UV resistance, ozone resistance and high temperature performance, no environmental pollution.
- It has good compatibility with other neutral silicone rubber.
How to use it?
- Recommends sizing before the first A, B were mixed to homogeneity, the user can also change the mixing ratio of the curing rate adjusted according to actual demand (volume ratio 8: 1-12: 1 between)
- It cannot be used in the construction before the adhesive material compatibility testing.
- It cannot be used in the construction under outdoor high-temperature environment when the substrate surface temperature exceeds 40 ºC.
- B component reactive group can react with water vapor in the air, so it cannot exposure to air long time.
