- Application Information
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., 20phr, Accelerator 2950 increases cure speed dramatically and coatings are open to foo 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.

No Leaching Effect:
Its unique amine functionality gives it the ability to co-react with the epoxy resin, making it part of the polymer backbone. The normal leaching is 5 times less than other accelerators, minimizing the impact on chemical or corrosion resistance properties.
Reference system: ARALDITE® GY 250 fully cured with IPDA based hardener ARADUR® 20315
Drying and Gel Time:
Accelerator 2950 offers a good balance between faster drying time and reduction of gel time also at low temperatures.
