This formula is available in two color options: clear, which helps reduce visible adhesive lines, and red, to help users see adhesive placement for improved accuracy and control during composite infusion applications in marine, aerospace, transportation, and industrial manufacturing. With fast, aggressive tack and low soak-in, 3M™ Super 77™ Classic Spray Adhesive is suited for quick layup work while offering the versatility to bond materials such as fabrics, foams, plastics, metals, and wood.
Built for application flexibility, 3M™ Super 77™ Classic Spray Adhesive can be applied from one side and used for either repositionable or permanent bonding, depending on technique. The available cylinder spray format gives users multiple ways to manage output through the spray tip, cylinder valve, and applicator trigger, helping deliver a spray pattern that can be matched to the application need. 3M™ Super 77™ Classic Spray Adhesive also boasts a shelf life of up to 21 months when stored at room temperature, making it a suitable option for a variety of production tasks.
