Neuthane™ 3100 MDI – PTMEG Ether Rotational Casting Systems (70Shore A–70 Shore D)
Properties
The Neuthane 3100 series are high performance MDI - PTMEG ether rotational casting systems designed to produce roller coverings in arduous application areas.
They offer:
- a high level of physical properties
- very good dynamic performance
- good hydrolysis resistance
- high resilience
- non MOCA curatives
- processing without moulds
- room temperature curing
Typical Applications
- Steel mill rollers
- paper mill rollers
Processing can be by hand or by dispensing machine
Hand Processing
- Melt prepolymer at 50-70°C for 12-24 hours
- Heat the prepolymer and curative to the recommended temperature
- Ensure that the curative is thoroughly mixed prior to use (the storage tank on the machine should be fitted with agitation to prevent separation during use)
- Degass to remove air
- Dispense at 700-2000g per minute*
- Adjust rotation and traverse speed until a smooth build up is achieved*
- Cure as recommended
* This will vary depending upon diameter of roller. As a general guide theoutput rate, rotational and traverse speeds will all increase as the diameter of the roller increases
Processing Considerations
- Avoid prolonged storage of prepolymers at elevated temperatures. This will result in low hardness and lower properties of the cured material
- Avoid moisture contamination of all materials
- Part used containers should be flushed with dry nitrogen and resealed
immediately after use - To prevent de-lamination, subsequent layers should be applied within 30 minutes
Alternatives
- Solvents/Abrasion/Cut resistance - Ester based systems should be considered: Neuthane 3200 [MDI rotational casting]
- Cost – Ester systems will offer cost savings: Neuthane 3200 [MDI rotational casting] PPG ether systems will also offer advantages [Neuthane 3300*]
