Shreebond HM 72C (HMMM 72C) – High-Purity Liquid HMMM Resin for Rubber-to-Cord Adhesion (Equivalent to CYREZ® 936 or PERGAMIN® HMMM 72C)

Shreebond HM 72C (HMMM 72C) – High-Purity Liquid HMMM Resin for Rubber-to-Cord Adhesion (Equivalent to CYREZ® 936 or PERGAMIN® HMMM 72C)

SHREEBOND HM 72C (HMMM 72C) is a high-performance liquid hexa methoxy methyl melamine resin with 72% active content. Designed for rubber-to-textile and rubber-to-metal bonding systems, it acts as a reliable methylene donor in two-stage resorcinol-based bonding formulations.

Its high purity and consistent molecular weight make it an excellent equivalent to well-known products like CYREZ® 936 and Pergamin® HMMM 72C. It is widely used in the tyre, rubber hose, conveyor belt, and automotive rubber industries.

Key Benefits

  • Strong bonding between rubber and polyester, nylon, or aramid cords

  • High active content (72%) ensures performance with lower dosage

  • Liquid form allows easy incorporation into masterbatch or emulsions

  • Offers scorch safety, thermal stability, and durable bonding under dynamic stress

  • Compatible with RFL dipping or dry bonding systems


Applications

  • Tyres (Bias and Radial)

  • Conveyor Belts

  • V-belts & Hoses

  • Rubber Profiles & Rubberized Fabrics

  • Cord-Rubber Composites

Ideal for use in resorcinol–formaldehyde–latex (RFL) systems, or added directly in rubber compounding as a methylene donor alongside resorcinol donors and reinforcing fillers.
