From boat hulls to commercial vehicles, the infusion molding industry continues to extend beyond wind blade manufacturing. When preparing a resin-infused composite, an adhesive used in the dry-layup must be compatible with the resins used, which is why 3M designed 3M™ Hi Tack Composite Spray Adhesive 71 specifically for these applications to allow the resins to work properly and yet still yield stronger composites.
3M’s new spray adhesive features several important 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 facilitates effective lay-up of fiber sheets with low soak-in for quick bonding times and turnarounds. 3M Hi Tack Spray Adhesive 71 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, US product marketer for 3M Spray Adhesives. “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.”
In addition to clear, the adhesive is available in green, allowing operators to ensure the appropriate amount is applied. The formula will work with most resin systems including polyester, vinyl ester, & epoxy. This versatile adhesive also bonds fiber, fabric, wood, laminate, metal and its strong tack is ideal for a variety of composite production applications.
