MS Polymer sealant technologies introduced by Kastar and Henkel

Two companies have announced advancements in MS Polymer sealant technology targeting different industrial sectors.

Kastar, a Chinese manufacturer, will showcase its MS971 Multi-purpose and MS973 Fast Dry MS Polymer Sealants at The Big 5 Global 2026 in Dubai. The company utilizes in-house silane-terminated polymer synthesis technology to develop products designed for adhesion, flexibility, and weather resistance in construction applications such as roofing, gutters, and concrete joints.

Henkel has launched Loctite MS 9810, a one-component MS Polymer formed-in-place gasketing sealant for the automotive industry. Designed for use in engines, electric drivetrains, and electronic housings, the non-silicone product is engineered to resist hydrocarbons, hot oils, and water-glycol fluids. The sealant cures at room temperature via atmospheric moisture and features a no-mix formulation intended to simplify manufacturing processes and reduce material waste.
