Key features:- Similar to RFE- NCO: 7.2 ± 0.2% by weight
- Appearance: clear yellow to brownish liquid
- Enhance the bonding strength of adhesive
- Increase the heat resistance of adhesive
Description: The light-color TPUA-E33D (similar to RFE) is an established, universal curing agent for adhesive based on hydroxyl polyurethane, natural and synthetic rubber. TPUA-E33D can be used instead of TPUA-13-F25G . RFE is even more satisfactory from the aspect of industrial hygiene.Application: After the addition of TPUA-E33D, 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, it may become increasingly difficult to apply and its viscosity increases rapidly until irreversible gelling ultimately occurs.
