Streamlined processing, primeless multi-substrate compatibility, and environmental responsibility expand design and compliance horizons 

Henkel Teroson MS 9381 HPT tin-free adhesive sealant delivers simplified, sustainable solution for heavy equipment sector

Düsseldorf, Germany – Henkel announces the expansion of its line of sustainable adhesive sealants for use with interior and exterior heavy equipment and vehicle applications. Teroson MS 9381 HPT complies with strict regulatory requirements, eliminating tin, solvents, isocyanates, silicones, and PVC from its formulation while simplifying processing and improving performance compared to older-generation materials. The UV-resistant formulation is multi-substrate compatible, making it effective for various applications, including cabin window glazing, side paneling and roof skin bonding, and seam and joint sealing. 

“With the introduction of its ‘Respect the Planet, Rethink Design’ initiative last year, Henkel reaffirmed its commitment to solutions that combine top performance and environmental responsibility,” says Leandro Pedro, Henkel Global Head of Market Strategy – Core and Value Segments. “The heavy equipment industry is evolving rapidly, driven by growing demands for efficiency and performance, stricter safety regulations, and ambitious sustainability targets. Manufacturers need more than products; they need solutions and partners who understand these pressures and simplify complexity at every step. Teroson MS 9381 HPT delivers on this promise: a high-performance adhesive that combines durability, reliability, and ISO-free safety with streamlined application, helping customers save time, reduce risk, and advance their sustainability goals without compromising performance and durability.”

Teroson MS 9381 HPT is a single-component, moisture-cure, silane-modified polymer (SMP), primeless adhesive sealant that simplifies the application process, reducing it to two steps versus the requisite three steps for conventional polyurethane (PU) materials. The adhesive’s high thixotropic properties and high position tack (HPT) ensure superior handling and application. These attributes help avoid potential errors, ensure processing efficiency, and offer the potential to lower the total cost of ownership. Furthermore, the ability to source a single material for multiple applications reduces supply chain and inventory control complexities. 

Additionally, Teroson MS 9381 HPT offers significant sustainability improvements. The elimination of numerous substances of very high concern (SVHCs) enhances health and safety, while at the same time offering validated emission-lowering capability. A product carbon footprint report from HEART* (Henkel Environmental Assessment Reporting Tool) indicates that, as compared to traditional PU processes, Teroson MS 9381 HPT can potentially reduce CO2 emissions by up to 50% from cradle to gate.

”Continuous innovation that prioritizes customer product performance, human health and safety, and carbon emission reduction is at Henkel’s core,” notes Pedro in conclusion. “Teroson MS 9381 HPT is completely aligned with these principles, further demonstrating our commitment to lead the heavy equipment and vehicle sector toward a more sustainable future.”

Enhanced silane modified polymer adhesive sealants can be used for many applications, including window glazing for cabins, side paneling and bonding of roof skin for vehicles, as well as seam and joint sealing.

SMPs provide effective adhesion to multiple substrates and demonstrate good UV resistance, which is ideal for interior and exterior applications.
