1. Product Overview

TEROSON® RB 3211 VT03 is a one-component, heat-curing antiflutter adhesive based on synthetic rubber technology. It is solvent-free, expandable, and flexible, offering excellent sag resistance and wash-off resistance without pre-gelling or pre-curing. The adhesive bonds effectively to oily steel, aluminum, and zinc-coated surfaces. After curing, it remains flexible, withstands temperature changes, and ensures safe corrosion protection due to its compatibility with E-coat paints. It is also paintable post-curing.


2. Applications

The product is designed for automotive body shop applications, providing strong adhesion to oily substrates. It is ideal where high elasticity over a wide temperature range is required, combined with resistance to wash-off before curing. Its low hardness prevents read-through effects, making it suitable for critical visible surfaces.
