New Water-based Rubber-to-substrate Automotive Bonding System
Noise, vibration, and harshness (NVH) components are critical to automotive manufacturing. For instance, a typical car contains up to 200 NVH components that combine rubber with other materials to isolate and dampen noise. The bonding of these components to automotive areas and parts is critical to their function and longevity.
NVH parts are traditionally manufactured using solvent-based bonding agents. However, as the regulatory landscape evolves and sustainability market demands grow, manufacturers are looking to formulate alternatives. One company, Stahl, has developed a new water-based alternative, dubbed the RelcaDur® system with two distinct products. The company reports that one of the products can be applied to vehicle parts such as the subframe mounts, chassis mounts, engine mounts, buffers, dampers and bushings and acts as a primer, protecting metal parts from corrosion, and the other can bond the rubber for vibration damping. The company reports that this is a durable, non-tacky and scratch-resistant material to build bonds during the vulcanization of the elastomer for automotive components and a more user-friendly system that does not require additions or adjustments for viscosity: just open, stir and apply.
