Polyurethane adhesive

When there is a trace of water or acid in the polyurethane system, it will react with the isocyanate to generate CO2, so that the product generates bubbles to affect the bond strength. The addition of molecular sieve activated powder with dispersibility and rapid  remove trace water and other small molecule impurities in the material and avoid bubbles. Molecular sieve activated powder has excellent dispersibility and can be perfectly compatible with polyethers, isocyanates and polyols, which are widely used at present.

Low-E glass

The special molecular sieve for hollow glass is a potassium-sodium aluminosilicate with a pore size of 3Å, which is a kind of 3A molecular sieve. It can deeply adsorb residual moisture and organic volatiles in the insulating glass interlayer, and the adsorption amount of N2 and O2 is very small, which can effectively prevent the glass interlayer from dewing and frosting, so that the insulating glass remains smooth and transparent at very low temperatures. At the same time, it fully reduces the strong internal and external pressure difference between the insulating glass due to the change of the season and the temperature difference between day and night, completely solves the problem of distortion and breakage caused by the expansion and contraction of the insulating glass, and fully prolongs the service life of the insulating glass.
