Permabond TA004370300C0101

TA437 Single Component Toughened Acrylic Adhesive, Orange, 300ml Cartridge

Permabond® TA437 is a single-component structural acrylic adhesive designed primarily for bonding metals, ferrites, and ceramics. The typical fixture time of TA437 when used with Initiator 41 is 20-30 seconds. The fast fixture time of TA437 makes it an ideal adhesive for high-speed production lines. When the use of the activator is not desirable, the material will cure anaerobically in a close-fitting joint / in the presence of metal, the fixture time will be 5-10 minutes. This product provides high strength, tough, durable bonds with good impact resistance.

Adhesion to a wide variety of substrates
Fast cure at room temperature
No mix application
High shear and peel strength
Good impact strength
High-temperature resistance
