Should manufacturers be required to prioritize replacing industrial chemicals with safer, non-toxic alternatives?
Henkel Adhesive Technologies has introduced Teroson MS 940, a new adhesive and sealant designed specifically for rolling stock applications. The product provides elastic bonding for windows, doors, and panels.
Why it matters
Train manufacturers face increasing industry pressure to utilize products free of isocyanates. This formulation addresses those regulatory and safety requirements while maintaining high tensile strength for dynamic rail loads.
The Teroson MS 940 utilizes a new polymer package to deliver mechanical performance across various rail applications. It is engineered to resist UV radiation, weathering, and harsh cleaning agents.
The players

The details
Designed for the rigors of rail travel, the adhesive delivers elastic bonding capabilities essential for dynamic loads. The chemical composition is specifically formulated to exclude isocyanates while meeting the durability demands for windows and panels.
Timeline
Henkel launched the Teroson MS 940 on September 24, 2026.
The Big Picture
This development follows a documented trend of removing hazardous isocyanates from industrial manufacturing to align with the European Union's REACH regulation on isocyanate usage. The shift indicates a broader movement toward safer, high-performance polymers in transit infrastructure.
The transition to isocyanate-free adhesives could set new safety standards for public transportation components. This change may eventually lead to more resilient, weather-resistant materials being used in future rail fleet production.
The takeaway
Manufacturers looking to upgrade their assembly processes should evaluate whether isocyanate-free alternatives can match the longevity of legacy bonding agents. Adopting these new materials now may help companies avoid future regulatory hurdles related to chemical safety.
