  • 1) SL-1401 resin is a superior tackifying resin, which can improve and maintain the tackiness of the compounds especially under the warm and humid conditions. Its tackifying property is equal to that of t-butyl phenol-acetylene resin.
  • 2) SL-1401 resin can improve the processing properties of rubber compounds. The presence of tackifier molecules on the surface of rubber compounds can prevent the oxidization and hardening of compounds and also, to ensure tackiness and plasticity.
  • 3) Curing properties of compounds will not be affected and the physical properties of vulcanizates will not be changed by the addition of SL-1401 resin.
    Due to superior solubility in rubbers, SL-1401 resin is especially applicable in tire or other high performance rubber adhesive products. SL-1401 is supplied in the form of pastilles without dust generation. Therefore, this resin can be easily mixed into rubber compounds. No contamination to equipments and workplace can be expected with SL-1401 resin.
  • 1) SL-1401 resin is preferably be added during the first stage of mixing to facilitate the uniform dispersion of this product into rubber compounds.
  • 2) It is recommended to use SL-1401 resin at 2-5 phr loading. The rubber processing oil level in the compounds can also be reduced properly.
    SL-1401 resin can be extensively applied to natural and synthetic rubbers, to produce high
    performance tires, convey belts, hoses, rollers, rubber plates, rubber inner liners, retread materials,
    wires and cables. This resin also can be used as tackifying agent in adhesives.


  • SL-1401 25kg( net weight), Kraft bag inner PE coated.


  • This material can be stable for 18 months under the normal storage conditions. However, precautions must be taken to avoid exposure to sunlight and always, store this material in a sealed container under the dry and cool conditions.
  • Refer to Material Safety Data Sheets (MSDS) prior to using this resin.
