AI Technical Summary
Technical Problem
Conventional adhesive compositions used for bonding plastic automobile parts fail to maintain high shear strength in high-temperature environments, leading to substrate surface damage and instability.
Method used
Incorporating acicular particles into the adhesive composition, which preferentially fracture under stress, thereby maintaining high shear strength and reducing substrate surface damage.
Benefits of technology
The adhesive composition with acicular particles exhibits enhanced shear strength and resistance to substrate surface damage in high-temperature conditions.
