    APPLICATIONS
  • 1)SL-3023 resin is broadly used in rubber adhesion system. This resin can enhance the adhesion between rubber and steel wire or synthetic fibers.
  • 2)SL-3023 resin forms network structure after reaction with methylene donors such as HMMM, HMT under vulcanization temperature. It improves adhesion between rubber and reinforcing materials through enhancing crosslink density in rubber.
  • 3) SL-3023 resin moves to the cord surface in rubber application because of polarity difference between resorcinol and rubber, to protect the steel cord and increase adhesive strength before and after aging.
    4) SL-3023 resin is a modified condensation product of resorcinol and formaldehyde which overcomes the fuming problems associated with the use of resorcinol and ití»s more eco-friendly.
  •  

    APPLICATIONS

  • It is suggested that the level of SL-3023 should be 1.2-2.0 phr in rubber application
