Taiwan PU TPUA-AC528 Hardener for Adhesive
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: Key features:
  • Similar to RC
  • NCO: 6.0 ± 0.2% by weight
  • Better heat resistance
  • Enhance the bonding strength of adhesive
  • Increase the heat resistance of adhesive
Description: The almost colorless TPUA-AC528 is designed as curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber; owing to TPUA-AC528 has the feature of good hot-resistance, it is particularly suitable for light-color polyurethane, adhesive system. Because the solvent is ethyl acetate , TPUA-AC528 can be used in those countries where the use of methylene chlorides is restricted

Application: After the addition of hardener for adhesive TPUA-AC528, the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only by its content of rubber, but also by the other ingredients of the formulation (e.g. resins, antioxidants, solvents, etc.) If the adhesive is not used within this period of time, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs.
