Aqueous Adhesives for Rubber-to-Substrate Bonding: Performance and Physical Properties Relationship

High performing aqueous based adhesives are becoming more attractive in the manufacture of engineered rubber devices, such as vibration and motion control devices. The driving forces for this trend are 1) the growing environmental regulations limiting volatile organic compounds (VOCs) of solvent based adhesives and 2) the growing demand for higher performing adhesives for engineered rubber devices, particularly  those used in automotive NVH (noise, vibration, and harshness) applications. This paper describes the performance characteristics of advanced aqueous adhesive in comparison to solvent and hybrid based adhesive systems for rubber-to-substrate bonding applications. The results are discussed in consideration of physical properties of corresponding polymer system and model adhesives.
