Neuthane 801 XP (3 Component Extra High Performance) MDI - PTMEG Quasi Systems (60A - 75D)
Properties
The Neuthane 801XP series are high performance MDI – PTMEG ether quasi sytems designed to produce items for use in arduous application areas.
They offer:
- a very high level of physical properties
- very good dynamic performance
- good hydrolysis resistance
- high resiliance
- low viscosity
- low process temperatures
Typical Applications
- Wheels (e.g.fork-truck, pallet-truck and press-on bands)
- In-line roller-blade wheels
- Mining and quarrying (e.g. screen-decks, scraper-blades)
- Hydrocyclones
- Automotive (e.g. suspension-bushes)
- Roll covering
Processing can be by hand or by dispensing machine
Hand Processing
- Long pot life enables hand processing
- Melt ISO component at 30-40°C, POLYOL component at 50-60C° 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 the 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, pre-heated to the recommended temperature.
- Cure as recommended.
Processing
- Pails or Drums must be melted and rolled so material is fully mixed before use
- 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.
Storage
- It is recommended to store NEUTHANE 801 ISO XP within the temperature range of 20-30 °C. At lower temperatures can deteriorate, because of the partial crystallisation of its 4,4'-methylenediphenyl diisocyanate content. At higher temperatures above 30 °C, it is not recommended since discolouration and formation of insoluble solids (dimerization) may occur which can lead to a viscosity increase and a decrease of NCO content.
- Recovery Procedure: If partial or entire freezing occurs, it is recommended to rapidly melt out NEUTHANE 801 ISO XP at 70°, typically for 16 hours or overnight.
