Improving Efficiency and Quality with an NVH Sustainable Solution

A rail customer had quality, efficiency and health & safety issues with a competitor product.

  • At a rail wagon the outer panel is stitch welded to the chassis (reinforcement beams). To avoid moisture and corrosion, the gap between panel and the reinforcement beam needs to be perfectly sealed. In time the product should be free of cracks. The competitor’s product became brittle causing moisture ingress that led to premature corrosion. Corrosion is the worst enemy of the steel construction.
  • This product showed difficulties in the application as it often started to cure in the feed lines and clogging up the dispensing gun.
  • The customer required additional manpower to ensure the product was evenly applied. This resulted in extra application layers by brush (touch-up).
  • The product was not compatible with the double-sided tape on the pre-cut insulation material the customer was using and was not compliant with health & safety regulations as it is a solvent-based product.

The Henkel expert team did preliminary tests and offered product sampling to understand further the customer’s challenge.

Henkel proposed TEROSON WT 218 FR – 200, a water-based and synthetic resin that is designed to be spray-applied using airless equipment. It can be dried at room temperature. It offers sound insulation properties, sealing and good abrasion resistance.
