Huntsman - Model 2950 -Accelerator
Accelerator 2950 is an effective accelerator and/or co-hardener when used in combination with polyamines, polyamidoamines and their adducts. It is used to cure liquid epoxy resins such as ARALDITE® GY 6010 resin, ARALDITE®PY 302-2 resin, or similar resins for solvent-free coatings and flooring systems. It is also used to cure solid epoxy resins or their solvent cuts such as ARALDITE® GZ 571 KX 75 resins for solvent containing marine and maintenance coatings. Accelerator 2950 is also an effective accelerator and co-hardener in polyurethane systems when used at 1-3% on binder.

In solvent free coatings:
- At low use levels, Accelerator 2950 produces the same effect as the industry standard tertiary amine such as Accelerator 960-1
- At high use levels, e.g., 20 phr, Accelerator 2950 increases cure speed dramatically and coatings are open to foot traffic after 24 hours at 5°C
In solvent containing coatings:
- At low use levels, Accelerator 2950 produces the same effect as Accelerator 960-1 but nearly twice the pot life
- At high use levels, Accelerator 2950 give the same effect as in solvent free coatings
In polyurethane systems:
- More dramatic results than in epoxy systems
- Extremely short de-molding times for tooling systems
- Co-hardener when used with polyamine, polyamidoamines and their adducts
- Good compatibility with amine hardeners
- Effective accelerator and co-hardener in polyurethane systems
- Good for low temperature and waterborne systems
