Permabond TA004390050B0101

TA439 High-Temperature Magnet Bonding Toughened Acrylic Adhesive, Amber, 50ml Bottle

Permabond® TA439 is a two-component structural acrylic adhesive designed primarily for bonding metals, ferrites, ceramics, and some plastics. The typical fixture time is 20-40 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 41 (or Initiator 43 for use on plastics).
