Typical Applications
|
Neuthane™ 801NG - C53 Series
(Catalysed 2 Component) MDI - PTMEG Quasi Systems 60 - 95 Shore A
Processing can be by hand or by dispensing machine
Hand Processing
- Melt ISO component at 30-40°C, POLYOL component at 50-60°C and BD at 40°C for 12-24 hours
- Ensure components are completely liquid and thoroughly mixed prior to use
- Bring all components to the recommended process temperature.
- Add pigments and Antifoam (as applicable) to the polyol component whilst mixing
- It is recommended that air be removed from the ISO component under vacuum
- prior to addition of the curative
- Add all components and thoroughly mix ensuring that no unmixed material is left on the container sides (if necessary the mix can be transferred to a second clean container and mixed again)
- Remove air under vacuum
- Cast into moulds, preheated to the recommended temperature
- Cure as recommended
Processing
- Avoid moisture contamination of all materials.
- Part used containers should be flushed with dry nitrogen and resealed immediately after use
- It is vital to ensure that both components are completely liquid and thoroughly mixed prior to use
- Due to the exothermic nature of the system, larger mixes will have a shorter pot life
Alternatives
- Solvents - ester based systems should be considered: Neuthane 200 [TDI], Neuthane 700 [MDI prepolymer] or Neuthane 802 [MDI quasi]
- Cost - Ester systems can be considered: Neuthane 700 [MDI prepolymer] or Neuthane 802 & 803 [MDI quasi]
- Temperature - Neuthane 100 [TDI PTMEG] or Neuthane 500 [Aliphatic Isocyanate] based systems may be considered
