Product Introduction of 3M Scotch-Weld Urethane Adhesive EC-3535 B/A
3M Scotch-Weld Urethane Adhesive EC-3535 B/A is a fast-acting, two-part urethane adhesive that cures at room temperature or with heat to form tough structural bonds with high impact resistance. This adhesive offers strong adhesion on metals, plastics, composites, and many primed or painted substrates. It becomes non-sag approximately 30 seconds after mixing, making it easy to handle and apply.
It features a 3-5 minute work life for precise application and positioning, with an 8-hour room temperature cure time or faster with heat. This allows flexible processing times to achieve required bond strength. The adhesive can be applied with a spatula, trowel, or flow equipment, providing versatility in application methods.
Urethane adhesives are known for their flexibility and versatility. They bond well to various materials, including wood, metals, rubbers, cured epoxy, leather, tile, glass, plastics, concrete, and more. Their chemical composition can be customized to achieve different levels of stiffness, flexibility, and hardness, allowing them to maintain bond integrity under varying environmental conditions.
Using a structural adhesive like 3M™ Scotch-Weld™ EC-3535 B/A offers numerous benefits, such as eliminating the need for mechanical fasteners, joining dissimilar materials, delivering clean finishes, and offering excellent environmental and chemical resistance. It cures without the need for air or moisture, ensuring consistent results with unlimited depth of cure.
3M remains a trusted partner in aerospace and related industries, known for its high-quality adhesives, sealants, and surface protection products. Their solutions enable faster processes, lower costs, and reduced waste through enhanced product performance and reliability.
