Perkacit DPG is used as a secondary accelerator in combination with thiazoles and sulfenamides in most of the sulfur cured elastomers.
In NR and SBR latices it is used as a gelling agent in foam processes.
- Perkacit DPG as a secondary accelerator shows a synergistic effect when used with thiazoles and sulfenamides giving faster cure rates and higher levels of mechanical properties in all general purpose elastomers.
- Perkacit DPG is generally not used alone as it tends to be very slow and scorchy.
- Due to discoloration it is generally not suitable for light colored compounds.
- Perkacit DPG can be used in latex as a secondary gelling agent (foam stabilizer) in the silico-fluoride foam process.
- Using Perkacit DPG gives fast cures with good reversion and fatigue resistance and better storage stability than obtained with formulations activated by thiurams and dithiocarbamates.
- Perkacit DPG is regulated for use in articles in contact with food as specified under FDA 21 CFR 177.2600 and under BgVV XXI, Categories 3-4. |
