This company designed 3M™ Hi Tack Composite Spray Adhesive 71 for specific applications to allow the resins to work properly and yet still yield stronger composites. The new adhesive features benefits for industrial, marine, transportation and composite manufacturers, including: quick-to-tack formula, visual control and little to no intrusion during the resin infusion process. The specialized formula reportedly facilitates lay-up of fiber sheets with low soak-in for quick bonding times and turnarounds. The adhesive is also built with high-adhesive solids content, so the product lasts longer and less is required.

“Infusion molding applications require very specific adhesive attributes and compatibilities between the resin and adhesive,” said Tim McNamara, U.S. product marketer. “3M Hi Tack Composite Spray Adhesive 71 is a great addition to our portfolio of spray adhesives because it offers little to no intrusion in the infusion process, which allows our customers to improve the strength of their final  composites.”
