Science Popularization of Thermal Conductive Epoxy Structural Adhesive | Principles, Characteristics, and Engineering Application System Analysis

01 | What is thermal conductive epoxy structural adhesive?Thermally Conductive Epoxy Structural Adhesive is a high-performance adhesive material that uses epoxy resin as the matrix, adds high thermal conductivity fillers, and forms a dense three-dimensional network structure through crosslinking reactions with curing agents. Its material essentially consists of three types of properties: ① Structural StrengthHigh shear strength, high peel strengthAnti impact, anti vibration, anti fatigueDimensional stability for long-term serviceIt can replace traditional mechanical fixing methods such as screwing, riveting, and welding.② Thermal ConductivityThermal conductive fillers (such as Al ₂ O3, BN, AlN) form a continuous thermal conduction chain during the curing process, giving the material significantly higher thermal conductivity than ordinary epoxy.This function is used for heat transfer of heating…
