Primerless-to-Glass Adhesives With 3-Hour MDAT — From DuPont

Beta seal™ U-428+HV and Betaseal™ U-838HV primerless-to-glass windshield adhesives now feature three-hour Minimum Drive-Away Times (MDAT) at working temperatures as low as 50°F and four-hour MDATs between 32°F and 50°F.

Both are one-component, conventional-cure, high viscosity adhesives. Each eliminates steps and speeds installations by incorporating glass primer functionality into the urethane. They are easy to gun and require no heating.

Representatives from DuPont say the two new adhesives are excellent for RV and motor home windshield replacement. They can also be used for quarter glass or other stationary glass, as well as backfilling to install reveal moldings or other trim.

Betaseal™ U-428+HV comes in a cartridge. U-838HV is available in sausage packs.
