- The product is ready-to-use with a 35°C pre-heating temperature and fast drying formula.

Introduction
Stahl has launched RelcaDur®, a new water-based bonding system designed to connect rubber to various substrates, including steel, aluminum, and plastic. This innovation addresses the growing need for effective noise, vibration, and harshness (NVH) solutions in the automotive industry.
Product Features
RelcaDur® is a two-layer system consisting of a primer and a bonding agent. The water-based formulation is non-toxic and free from carcinogenic, mutagenic, and reprotoxic (CMR) chemicals, aligning with evolving regulatory standards and environmental awareness.
Application and Benefits
The system is applicable to vehicle parts such as subframe mounts, chassis mounts, engine mounts, buffers, dampers, and bushings. RelcaDur® 300 serves as a primer to protect metal parts from corrosion, while RelcaDur® 600 ensures effective rubber bonding for vibration damping. The result is a durable, non-tacky, and scratch-resistant material.
Ease of Use
RelcaDur® is user-friendly, requiring no additional adjustments for viscosity. It is ready-to-use with a 35°C pre-heating temperature and a fast-drying formula, simplifying the application process for manufacturers.
