3M™ Hi-Tack Composite Spray Adhesive 71, Clear, Large Cylinder (Net Wt 30 lb), 1 Each/Case

3M™ Hi-Tack Composite Cylinder Spray Adhesive 71 is a high-tack cylinder spray adhesive designed to support efficient composite manufacturing. Engineered for dry lay-up and resin infusion processes, it delivers fast tack, high strength, and reliable shear holding power to help stabilize materials during assembly. A consistent fine mist spray pattern provides controlled coverage, helping to reduce voids while securing fibers, fabrics, wood, and other lightweight substrates. Optimized to minimize intrusion into resin systems, 3M™ Hi-Tack Composite Cylinder Spray Adhesive 71 helps maintain laminate integrity while supporting consistent composite part production.

In composite manufacturing, material placement and stability are critical to maintaining part quality. 3M™ Hi-Tack Composite Cylinder Spray Adhesive 71 is formulated to help hold reinforcement materials in place during complex layups, allowing technicians to position fibers and fabrics more efficiently before resin infusion. The adhesive dries in approximately 15–60 seconds and provides a working bond range of up to 20 minutes, helping to balance speed and flexibility during production. Compatible with common composite resin systems, including polyester, vinyl ester, and epoxy, it supports a wide range of manufacturing environments. This formula is available in clear or pink for improved visual control during application.
