Material Notes:
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 30 – 45 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 can be used by itself but the fixture time will be 3-5 minutes. This product provides high strength, tough, durable bonds with good impact resistance. Features & Benefits: 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 Information provided by Permabond.
