Two part silicone sealants

Polysulphide sealant/Two part silicone sealants


Scenery two component silicone sealants mainly used as the second barrier sealing or the insulating glass. Part A is white, part B is black, mixed into black together. According to the mixing rate as 10:1, stagnant, high flexibility, high modulus, neutral cure, achieving excellent bonding and sealing performance without primer, has good extensibility, water-proofing function, especially for the insulating glass second barrier. Suitable to most construction materials, such as in the insulating glass, stones, aluminum or other metal constructions. 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 also has good compatibility with other neutral silicone rubber.




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 .

B component reactive group can react with water vapor in the air, so it cannot exposur to air long time. Stored below 27  dry place, safe storage period of 6 months.

Instruction

1.      Recommends sizing before the first A, B were mixed to homogeneity (volume ratio 10:1)

2.      It cannot be used in the construction before the adhesive material compatibility testing.

3.      It cannot be used in the construction under outdoor high-temperature environment when the substrate surface temperature exceeds 40 .

4.      B component reactive group can react with water vapor in the air, so it cannot exposure to air long time.

Storage and package

Stored below 27 dry place, safe storage period of 6 months
