Japan has introduced a new high temperature epoxy adhesive

3M company began selling epoxy resin adhesives that maintain adhesion at high temperatures - 3M Scotch-Weld structural adhesives "IW2460", "IW2190", "IW3450". The product is mainly intended for motors, generators, transformers and electronic components such as near the heat source, as well as near the car engine and other parts exposed to high temperatures.

 

IW3450 is a two-liquid mixed hardening glue, can be hardened at room temperature,it is easy to operate. And it has an adhesive force of 18 MPa in an environment of 80 ° C.

 

IW2460 and IW2190 are single-component, heat-hardened adhesives, The IW2460 is characterized by an adhesive force of 25 MPa in an environment of 150 C. IW2190 improves the toughness at high temperatures and can withstand temperature changes when bonding dissimilar materials When the coefficient of thermal expansion caused by the different peel stress. The strip has a peel strength of 5.4 kN / m.
