AI Technical Summary
Existing adhesives for adhering sound-absorbing materials to pneumatic tyres have limitations such as a narrow application temperature range, poor moisture resistance, rapid curing, and require perfect surface fit, which complicates application, especially for uneven surfaces.
An adhesive composition comprising elastomers like isobutylene isoprene rubber, plasticizers, tackifiers, and vulcanizing agents, with a formulation that allows for broader application temperatures, improved moisture resistance, and reduced cure time, enabling effective adhesion without requiring precise surface preparation.
The adhesive composition provides enhanced adhesion with a broader temperature range, better moisture resistance, faster application, and longer shelf-life, ensuring effective bonding of sound-absorbing materials to pneumatic tyre surfaces.
