Product Description
Detailed Specifications And Features
Bonding Resins for Tire and Conveyor Belt Production
Specialized adhesion promoters used in the production of tires, conveyor belts, and similar products to enhance bonding strength between rubber and steel or polyester cords.
Adhesion Promoter SR022
SR022 is a pre-condensate of resorcinol, styrene and formaldehyde specifically formulated for rubber adhesion systems. This advanced compound significantly improves bonding strength between rubber and various fiber materials.
Key Features and Benefits
  • Reacts with methylene donors during vulcanization to form bonding resins
  • Creates dual bonding mechanisms: chemical bonding with cords and curing with rubber double bonds
  • Enhances adhesion between synthetic fiber cords, brass-plated steel cords, and vulcanizates
  • Improves mechanical and dynamic properties
  • Provides superior performance retention after aging
  • Non-fuming formulation - superior to pure resorcinol and masterbatch R-80
Application Fields
Widely used in tire manufacturing and conveyor belt production to promote adhesion between rubber and framework materials including steel cords and Nylon fibers.
Application Recommendations
  • Incorporate SR022 during the first stage of the mixing cycle
  • Recommended dosage: 1.5-2.0 phr
