In the field of automobile maintenance in China, it has always paid insufficient attention to the POLYURETHANE SEALANT FOR WINDSHIELD GLAZING. It is considered that china POLYURETHANE SEALANT FOR WINDSHIELD GLAZING is a kind of irrelevant automobile auxiliary material, which leads to the flooding of low-fat adhesive or building glass adhesive into the automobile glass replacement market, resulting in great potential safety hazards for the accident vehicles after repair.

China POLYURETHANE SEALANT FOR WINDSHIELD GLAZING  is a material for bonding and sealing various glasses with other substrates. It is mainly divided into two categories: silicone adhesive and polyurethane adhesive (PU) - one component polyurethane adhesive for polyurethane sealant for windshield - paste mixed with polyurethane prepolymer as the main component and other auxiliary materials. After extrusion, moisture solidifies to form elastomer with bonding and sealing effect on automobile window glass - Hg / T 4363-2012

Cleaning activator: liquid material used to clean and activate the surface of substrate to enhance the adhesion of primer and adhesive.

Primer: a liquid coating used on the surface of the substrate to improve the adhesion of the adhesive to the substrate and prevent ultraviolet rays from directly irradiating the adhesive surface through the window glass.

Product characteristics of china POLYURETHANE SEALANT FOR WINDSHIELD GLAZING (requirements)

1. One component, wet curing;

2. Thixotropy is good, and the facade is glued without collapse;

3. No corrosion and impact on glass and organic coatings;
