Loctite TEROSON MS 9380 - High Viscosity Automotive Joint & Seam Sealant

Loctite TEROSON MS 9380 is a high-performance, one-component silane modified polymer (SMP) sealant engineered for elastic bonding and sealing in automotive manufacturing applications. Designed with engineers in mind, this advanced adhesive delivers reliable structural flexibility, excellent substrate adhesion, and superior environmental resistance—making it ideal for side panel bonding, roof skin assembly, and seam sealing.

Its high viscosity, sag-resistant formulation ensures precise application on vertical and overhead surfaces, while moisture-curing chemistry provides a durable, elastomeric bond without the need for mixing. Free from solvents, isocyanates, silicones, and PVC, TEROSON MS 9380 supports safer, cleaner production environments without compromising performance.

Engineered for both interior and exterior use, this sealant offers strong UV resistance and consistent curing behavior dependent on environmental conditions, with options for accelerated curing in two-component applications.
