Product Description

Product Description

HW-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 as128 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 901X75 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.

Features:

1. Co-hardener when used with polyamine, polyamidoamines and their adducts

2. Good compatibility with amine hardeners

3. Effective accelerator and co-hardener in polyurethane systems

4. Good for low temperature and waterborne systems

Application:

1. In solvent free coatings:

    At low use levels, Accelerator 2950 produces the same effect as the industry standard tertiary amine such as Accelerator DMP-30.

    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.

2. 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.
3. In polyurethane systems:

    More dramatic results than in epoxy systems.

    Extremely short de-molding times for tooling systems.
