3M 7000119846 Fiberglass Matting Adhesive 400 Ml

Product Description

The 3M 7000119846 is a low-viscosity, two-part urethane fiberglass matting adhesive supplied in a 400 mL cartridge. It is formulated to saturate fiberglass cloth during the preparation of backup patches, providing the resin matrix needed to bond and stiffen the cloth before it cures in place. The adhesive is also suited for filling cracks, channels, and confined areas where applying a standard adhesive bead is not practical. Installers and repair technicians working with fiberglass reinforcement applications rely on this product for its fluid consistency, which allows thorough cloth saturation without dry spots or voids.

This adhesive is used in fiberglass patch and repair work across a range of trade and industrial applications. Its low viscosity makes it well suited for situations where the substrate has irregular geometry or where a reinforcing cloth must conform tightly to a curved or recessed surface before the resin sets. It is also used to address cracks and channels that require fill material prior to finishing. Technicians in body repair, industrial maintenance, and construction trades commonly use this type of two-part urethane where structural reinforcement with fiberglass cloth is required.

Key Features

• Low viscosity formula thoroughly saturates fiberglass cloth without pooling or running excessively
• Two-part urethane system provides structural bonding and stiffening once cured
• Suitable for filling cracks, channels, and areas where a standard adhesive bead cannot be applied
• 400 mL cartridge format supports controlled dispensing during patch preparation
• Designed for backup patch applications requiring fiberglass cloth reinforcement

Compatibility

Designed for use with fiberglass cloth in backup patch preparation and crack-fill applications across repair and maintenance work where a low-viscosity two-part urethane adhesive is specified.

Installation Notes

This product is a two-part urethane and must be mixed according to the manufacturer's mixing ratio before application. Ensure the substrate is clean, dry, and free of loose material before saturating fiberglass cloth or filling cracks. Use appropriate personal protective equipment including gloves and eye protection when handling two-part urethane systems. Work in a well-ventilated area and observe all applicable safety data sheet guidance for handling and disposal.
