￥

Detail:

SPC-20 one-component polyurethane adhesive is a moisture-curing adhesive, which is cured by the small amount of moisture adsorbed in the air and on the surface of the adherend. It can also be artificially sprayed on the surface of the adhesive to promote curing. After curing, the adhesive layer is insoluble and does not melt. The product has superior performance and convenient construction. It is widely used in the cross bonding of metal plates, wood and various fireproof and thermal insulation materials in the door industry.
