3M日本公司近日推出在高温环境中也能保持粘接强度的3M Scotch-Weld环氧树脂结构胶(IW2460、IW2190和IW3450)。该结构胶可用于马达、发电机、变电器和电子部件等发热源附近以及汽车发动机附近等暴露于高温环境中的部位。IW2460和IW2190是单组分热固化型胶粘剂,前者在150℃时具有25 MPa的粘接强度;后者则提高了高温韧性,在粘接异种材料时可耐受温度变化导致热膨胀系数不同所引起的剥离应力,对钢板具有5.4 kN/m
3M Japan recently introduced 3M Scotch-Weld Epoxy Structural Adhesives (IW2460, IW2190, and IW3450) that maintain bond strength in high temperature environments. The structure of plastic can be used for motor, generator, transformer and other electronic components near the heat source and the vicinity of the car engine exposed to high temperature environment parts. IW2460 and IW2190 are one-part thermosetting adhesives with the former having a bonding strength of 25 MPa at 150 ° C and the latter increasing the high temperature toughness that can be tolerated when different materials are bonded resulting in different coefficients of thermal expansion Peel stress of 5.4 kN / m on steel
