Shreebond HM-385 – High Performance HMMM Resin for Moisture-Curable Tire & Rubber Applications

Shreebond HM-385 – High Performance HMMM Resin for Moisture-Curable Tire & Rubber Applications

SHREEBOND HM-385 is a special-grade hexamethoxymethyl melamine (HMMM) resin developed specifically for the rubber and tire industry. It acts as a methylene donor and crosslinking agent, enhancing the adhesion between rubber and reinforcing materials like steel or polyester cord. Known for its moisture-curing reactivity, HM-385 plays a critical role in systems requiring durability, thermal stability, and long-term bond integrity.

This resin is ideal for high-performance rubber compounds used in tyres, belts, hoses, and mechanical rubber goods.
