Resistant Direct Glazing Adhesives

One-component polyurethane adhesives for direct glazing are widely used in the automotive industry. Since about 5% of car s windshields every year are damaged. [Pg.432]

Drive-away time defines the fit-for-use of vehicle after windshield repair. [Pg.433]

The definition of 5afe-Drive-Away Time (SDAT) is the time required for curing of the windshield adhesive to achieve full passenger retention in the case of a defined crash (Fig. 69). [Pg.433]

With short safe-drive-away times, costs are reduced and customers can put the car in service faster. To achieve windshield retention in the event of a frontal barrier impact, partly cured adhesives must have high initial tensile strength and fracture energy. Additionally, they must also fulfill the original equipment specifications such as good corrosion resistance, antenna suitability and mechanical performance. [Pg.433]

Direct glazing adhesives are multi-functional and can cope with several demanding specifications. They are based on a modular system, described in Fig. 70. [Pg.433]
