Product Description

Rhenogran® Resorcin-80/SBR is a masterbatch containing 80% resorcinol in a SBR binder, designed for use in direct bonding systems such as the resorcinol–formaldehyde–silica (RFS) system. In combination with a formaldehyde donor (e.g., Rhenogran® HEXA-80 or Cohedur® A250), it forms a resorcinol–formaldehyde resin during vulcanization, which is essential for robust bonding between rubber and reinforcing materials like textiles, glass fibers, and steelcords.
The low-dust, polymer-bound form ensures safe handling, clean processing, and fast, even dispersion. This system is widely used in tires, conveyor belts, V-belts, hoses, and other reinforced rubber goods. The pre-dispersed form ensures rapid incorporation and excellent dispersion, maximizing the bonding performance of resorcinol in industrial practice.

THESE SPECIAL FEATURES MAKE THIS PRODUCT SO SUCCESSFUL
  • Enables strong, durable bonding of rubber to textiles, glass fibers, and steelcords
  • Pre-dispersed in SBR for low-dust, easy handling and uniform distribution
  • Forms in-situ resorcinol–formaldehyde resin for high adhesion during vulcanization
  • Compatible with all common rubber types and reinforcement materials
  • Proven performance in demanding dynamic and static applications

THE MOST COMMON AREAS OF APPLICATION
  • Tires (carcass, belt, bead, and sidewall reinforcement)
  • Conveyor belts, V-belts, round belts
  • Fire hoses and other reinforced hoses
  • Flexible containers and fabric-reinforced rubber goods
  • Technical rubber articles requiring textile or metal reinforcement
