3M 7100039246 Instant Adhesive Clear 1 Pound

Product Description

The 3M 7100039246 is a medium-viscosity instant adhesive designed for bonding plastics, rubber, and other difficult-to-bond substrates. Sold under the Scotch-Weld PR600 formulation, this clear adhesive is engineered for applications where standard cyanoacrylates fail to achieve reliable adhesion. It performs well on substrates such as EPDM rubber and nylon, which are common in HVAC gaskets, seals, and mechanical assemblies. Technicians in HVAC, plumbing, and general mechanical service use this adhesive when field repairs or component fabrication require a fast-setting, strong bond on non-porous or low-surface-energy materials.

This adhesive is suited for light industrial and trade service environments where rubber and plastic components require a durable, clear bond. Typical applications include sealing EPDM gaskets, bonding nylon fittings or brackets, and repairing rubber-to-plastic assemblies encountered in HVAC and plumbing installations. Its medium viscosity allows controlled application on vertical or irregular surfaces without excessive run-off, making it practical for in-field use.

Key Features

• Medium viscosity formula allows controlled application on irregular and vertical surfaces
• Formulated for difficult-to-bond substrates including EPDM rubber and nylon
• Clear cure leaves bonds visually clean on finished assemblies
• Fast-setting instant adhesive chemistry reduces clamp time in field repairs
• Sold in a 1-pound unit suitable for shop or job-site use

Compatibility

Designed for bonding plastics and rubber substrates, including EPDM and nylon, as stated by the manufacturer for the Scotch-Weld PR600 formulation.

Installation Notes

Apply to clean, dry, and degreased surfaces for best bond strength. Instant adhesives set rapidly on contact, so align components before joining. Work in a ventilated area and avoid skin contact, as cyanoacrylate adhesives bond skin immediately. Follow all applicable safety data sheet guidance for handling and storage.
