DUPONT BETASEAL™ U-428+ HV is a professional-grade, high-viscosity polyurethane adhesive designed for windshields, back glass, quarter glass, and other direct-glazed stationary automotive glass installations. Its primerless-to-glass formula incorporates glass primer into the urethane, helping streamline installation while providing a strong, dependable bond.

This listing includes 4 tubes of BETASEAL™ U-428+ HV adhesive—ideal for professional installers, multiple repairs, or approximately two typical windshield or back-glass installations.

Important: A high-thrust, heavy-duty caulking gun is required. A 26:1 ratio caulking gun is recommended.

Application

Helpful Tips

  • This is a high-viscosity (thick) professional adhesive.
