ergo structural adhesives for rail transport - with tested fire behaviour according to DIN EN 45545-2  

Passenger safety plays a central role in rail transport - this naturally includes fire protection. The fire behaviour of materials used must be intensively tested and classified. This, of course, also applies to the adhesives and sealants used.  

Toxic gases and smoke, which needs to be examined in detail, can develop in the event of fire, particularly when plastics and adhesives are involved. Flammability and - in the event of fire - continued burning behaviour are also important technical properties to take into account when selecting these materials. The second part of the DIN EN 45545 “Fire protection in railway vehicles” standard regulates the requirements for fire behaviour of materials and components. This gives processors a guideline as to which adhesives are suitable for which applications and their respective fire protection requirements. 

Kisling AG is fully aware of its responsibility in such demanding applications. Adhesives selected were therefore extensively tested in a special fire laboratory. The three ergo structural adhesives ergo. ® 1675, ergo 7430 and ergo 7440 are new and have been tested and certified for smoke toxicity (ISO 5659-2), heat generation (ISO 5660-1) and flame propagation (ISO 5658-2). They meet the requirement sets R1, R7 and R17 of DIN EN 45545-2 with the best grade HL1-3 (hazard level 1 - 3). 

The two-component epoxy resin (ergo 7430, ergo 7440) and methacrylate adhesives (ergo 1675) also make a significant contribution in terms of process simplification, acceleration and safety.
