Material Notes:

Permabond® TA439 is a two component structural acrylic adhesive designed primarily for bonding metals, ferrites, ceramics and some plastics. The typical fixture time of is 10-30 seconds. The fast fixture time of TA439 makes it an ideal adhesive for high speed production lines. This product provides high strength, tough, durable bonds with good impact resistance and performs well in drop tests. TA439 is methacrylic acid free, this means it is suitable for use on sealed electric motors and will not cause corrosion to sensitive components. Use TA439 with Initiator 43. Mix ratio 10:1.5 (adhesive:initiator). Features & Benefits: Adhesion to a wide variety of substrates Fast cure at room temperature No mix application High shear strength Good peel and impact strength Good chemical resistance Non-corrosive formulation Information provided by Permabond.
