Key features:- Similar to RN
- NCO: 5.8 ± 0.2% by weight
- Non-yellowing- Enhance the bonding strength of adhesive
- Increase the heat resistance of adhesive
Description: The almost colorless PU hardener TPUA-ACFN (NON YELLOWISH) is designed as curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber; owing to PU hardener TPUA-ACFN (NON YELLOWISH) features good hot-resistance, it is particularly suitable for light-color polyurethane adhesive system. Because the solvent is ethyl acetate, PU hardener TPUA-ACFN (NON YELLOWISH) can be used in those countries where the use of methylene chloride is restricted.Application: After the addition of PU hardener TPUA-ACFN (NON YELLOWISH), the ready-to-use double-component adhesive should be applied within a period (pot life) which is determined not only 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, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs Information provided by Taiwan PU Corporation |
