💡 In This Article Why an epoxy adhesive with excellent initial adhesion can lose adhesion after reliability testing How differences in coefficient of thermal expansion (CTE) affect the adhesive interface How cracks initiate and propagate under repeated thermal shock conditions In the previous article (Does More Toughener Always Mean Better Adhesion?), I covered the optimum … Continue reading Why Does Adhesion Fail Later Even When It Was Good Initially? — How Thermal Shock Causes Adhesive Failure →
