Automobile seal strip is one of the important parts of the automobile, widely used in doors, Windows, body, seats, sunroof, engine case and trunk and other parts, with waterproof, sealing, sound insulation, dust, antifreeze, shock absorption, heat preservation and energy saving important role.The rubber flocking seal occupies a very important position in the automobile seal system. The rubber flocking seal includes the door and window glass guide seal and waist seal. In addition to the basic sealing and reducing the wind noise function, it also provides the guide rail and support for the glass lifting.

The choice of flocking glue should first test that the glue matrix and sealing strip elastomer have good infiltration. Flocking glue is divided into solvent-based glue and water-based glue, and can be divided into single component and double component according to the curing reaction mechanism.In the actual production of rubber flocking seal strips, polyurethane as the matrix xylene or ketone as the solvent is usually selected as a single component adhesive, but this solvent based flocking glue price is high, and has volatile organic solvent, serious harm to the health of the construction personnel and users.

It is also a fire hazard when baked at high temperatures. Waterborne polyurethane flocking glue, instead of the previous use of solvent flocking glue, non-toxic environmental protection, is a new generation of green products.
