Henkel launches isocyanate-free adhesive and sealant for rail and industrial bonding

Henkel Adhesive Technologies has launched Teroson MS 940, a one-component elastic adhesive and sealant formulated without isocyanates, built on a new polymer package. The product exceeds standard silane-modified polymer (SMP) solutions in elongation and tensile strength and is aimed at window, door and panel bonding in railway carriages, vehicle body manufacturing and general industrial assembly. It offers primerless adhesion to metals, coated surfaces, glass and plastics, cures with atmospheric moisture, and is rated for service temperatures from -40°C to +100°C.

Key facts

Market context

Structural elastic adhesives and sealants bond and seal panels, windows and doors where welding, riveting or mechanical fastening is impractical or adds weight. In rail and vehicle body work, these products join dissimilar materials such as metals, glass and plastics, and must tolerate vibration and wide temperature swings. Polyurethane systems have long dominated this segment because of their toughness, but their isocyanate content brings handling and workplace safety requirements. Silane-modified polymers (SMPs) offer an isocyanate-free alternative and have been gaining share in construction and assembly. Formulators competing in this space typically compete on elongation, tensile strength, primerless adhesion and cure speed. Demand is driven mainly by railway carriage production, automotive body assembly and general industrial manufacturing. Gains in isocyanate-free chemistry can shift volume among suppliers of polymer intermediates and finished sealant products, rather than changing overall raw material supply.
