Allnex Amino Resin CYREZ

The Allnex Amino Resin CYREZ series comprises advanced HMMM (hexamethoxymethylmelamine) engineered for high-performance bonding and crosslinking in rubber-to-substrate applications. Utilizing precipitated silica as a carrier, these resins enhance adhesion between rubber and organic/textile cords or steel reinforcements in dry bonding systems, outperforming traditional hexamethylenetetramine (HEXA/HMT) solutions with superior durability and chemical stability.

Formulated with 65–72% active HMMM content, the series optimizes HRH (hydrated silica-resorcinol-hexamethylenetetramine) systems to deliver robust interfacial adhesion in tire manufacturing, industrial belting, and automotive components.

Applications span radial tires, conveyor belts, and vibration-damping components, where enhanced bond integrity and fatigue resistance are paramount.
