3M Hi-Tack Composite Spray Adhesive 71 High Tack Aerosol Glue for Fiberglass Carbon Fiber Layup Infusion

3M Hi-Tack Composite Spray Adhesive 71 – High Tack Aerosol for Composite Layup

Engineered for the demanding world of composite fabrication, the 3M Hi-Tack Composite Spray Adhesive 71 is the trusted choice of aerospace, marine, and industrial composite manufacturers. Its aggressive, high-tack formula holds dry fiber reinforcements — fiberglass, carbon fiber, and aramid — firmly in position during layup and infusion processes, preventing shifting and ensuring precise fiber orientation for superior finished part quality.

Key Features

• High tack aerosol – aggressive initial grab to hold fabrics in place during layup
• Compatible with fiberglass, carbon fiber, aramid, and other dry fiber reinforcements
• Suitable for wet layup, vacuum infusion, and resin transfer molding (RTM) processes
• Low migration – minimizes contamination of resin systems
• Spray application for fast, even coverage over large surface areas
• Repositionable – allows adjustment before final placement
• Does not inhibit resin cure

Typical Applications

• Fiberglass and carbon fiber layup positioning
