Tuffbond® 394 is a single-component epoxy adhesive designed for high temperature resistance and excellent adhesion to various substrates. With heat activation and color change upon cure, it offers a practical solution for bonding applications above 200ºF. This solventless adhesive cures on demand, ensuring high shear strength and rigidity post-cure. Its compliance with ISO-9001 standards and low water absorption make it a reliable choice for industrial and institutional applications.
