CH-860 polyurethane concrete sealant is a kind of single-group moisture-gas-separation solidification type polyurethane sealant. It can be applied for the adhesive of vehicle window glass or vehicle body sheet. It not only has the advantages of ageing-resistant, water-resistance, oil-resistance but also the excellent performance of low temperature resistance and shocking-resistance when it is used for assembling vehicle window glass. It features simple construction and can improve the vehicle's sealing and rigidity, reduce shocking and noise inside the vehicle.
The solidification speed is fast when Ch-860 polyurethane adhesive is used for adhesive and sealing, with high strength and good thixotropy, one adhesive glue-line with high strength and good elasticity will be formed after it being solidified. This product show thick mushy, has higher initial stage adhesive strength, suitable for applied at production line, it is the most ideal material for the adhesive and sealing of structure at automobile assembling.
