3M 7100079772 Single Step Primer 30 Ml Windshield

Product Description

The 3M 7100079772 is a single-use windshield primer formulated to promote urethane adhesion between the glass and the vehicle pinchweld. Sold in a 30 mL single-step applicator, it prepares the bonding surface before urethane sealant is applied during windshield replacement. The formula also serves as a touch-up solution for scratches on the pinchweld and can be applied to encapsulated glass edges. Auto glass technicians and body shop professionals rely on this primer as a critical first step in achieving a proper, long-lasting urethane bond.

This primer is used in automotive glass replacement applications, specifically where urethane adhesive is the bonding agent. It is suited for both OEM-style windshield replacements and aftermarket glass installations. The single-use format eliminates contamination risk between jobs, making it a practical choice for mobile glass installers and shop technicians working on passenger vehicles and light trucks.

Key Features

• Promotes urethane adhesion to windshield glass surfaces
• Single-use 30 mL format prevents cross-contamination between applications
• Suitable for touch-up of pinchweld scratches prior to glass installation
• Compatible with encapsulated glass edges
• Streamlines the prep step in urethane-based windshield bonding workflows

Compatibility

Designed for use as a pre-application primer with urethane-based windshield adhesive systems on passenger vehicles and light trucks where pinchweld preparation or encapsulated glass priming is required.

Installation Notes

Application is typically performed by an auto glass technician or body shop professional as part of a full windshield replacement procedure. The primer must be fully dried before urethane adhesive is applied; follow the adhesive manufacturer's open-time and drive-away-time guidelines. Avoid contact with skin and eyes, and ensure adequate ventilation during use. Do not reuse a single-use applicator on a second installation.
