Neuthane 802NG C53 2- Component Catalysed Series
Neuthane™ 802-NG Series (2 Component) MDI - Ester Quasi Systems (55A - 95 Shore A)
Properties
The Neuthane 802 series are high performance MDI - ester quasi systems designed to produce items for use in arduous application areas.
They offer:
- a high level of physical properties
- good cut and abrasion resistance
- good chemical resistance
- higher levels of physical properties at low end of
the hardness range compared to TDI systems - low process temperatures
Typical Applications
- Wheels (e.g. pallet truck)
- Mining and quarrying (e.g. screen decks, scraper blades)
- Oil and gas industry (e.g. gaskets, pipe pigs)
- Automotive (e.g. suspension bushes)
- Concrete Industry (e.g. moulds for decorative slabs and walls)
Processing can be by hand or by dispensing machine
Hand Processing
- Melt ISO component at 45-55°C, POLYOL components at 55-60°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 materialis 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 Considerations
- 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
- Humid/Wet - PTMEG ether based systems should be considered: Neuthane 100 [TDI], Neuthane 600 [MDI] or Neuthane 500 [Aliphatic]
- Dynamic/Resilience - PTMEG ether based materials should be considered: Neuthane 100 [TDI], Neuthane 600 [MDI] or Neuthane 801 [MDI Quasi]
- Temperature – Neuthane 100 [TDI PTMEG] or Neuthane 500 [Aliphatic Isocyanate] systems may be considered
