Examples of use
Flexible bonding for use in metalworking, plant and machinery engineering, plastics, ventilation and air conditioning technology, as well as in the construction of vehicle bodies, railcars, vehicles, and containers. Specially suited and tested for flame-retardant sealing or bonding of components in the interior and exterior of rail vehicles in accordance with fire safety standard EN 45545-2, requirements R22+R23, meeting the highest requirements for oxygen index, smoke density, and the release of toxic substances. Merbenit RV55 meets the highest requirements for hazard level HL 3, which authorizes its use in all operating classes 1–4 (including vehicles without evacuation options that are structurally suitable for tunnels). Merbenit RV55 is label-free, low-odor, and very easy to apply.

The data is based on measurements taken after 3 months. Application examples: Flexible bonding in the fields of metal, apparatus, and mechanical engineering; plastics, ventilation, and air conditioning technology; and bodywork, railcar, vehicle, and container construction. Specially suitable and tested for flame-retardant sealing or bonding of components in the interior and exterior of rail vehicles in accordance with fire safety standard EN 45545-2, requirements R22+R23, meeting the highest requirements for oxygen index, smoke density, and the release of toxic substances. Merbenit RV55 meets the highest requirements for hazard level HL 3, which authorizes its use in all operating classes 1–4 (including vehicles without evacuation capability that are designed for tunnel use). Merbenit RV55 is label-free, low-odor, and very easy to apply. Adhesion spectrum: Suitable materials include metals, powder-coated, painted, galvanized, anodized, chromated, or hot-dip galvanized surfaces, various plastics, ceramics, stone, concrete, and wood. Due to the wide variety of different plastics and compositions, as well as materials prone to stress cracking, preliminary tests are recommended.
