EDI CHARGE ENHANCING AGENT

Product Name:
EDI CHARGE ENHANCING AGENT
Properties:
Welled EDI Charge Enhancing Agent is a quaternaries imidazoline that can be used as a charge enhancing agent to improve transfer-efficiency for powder coatings. This usage allows reducing resin consumption-MORE COST SAVING.
Specifications:
Description              Specification          Description       Specification
Appearance             Pale-yellowing powder    Melting range     140-145℃
Amine value(mg KOH/g)  165-185[DIN16945]       Volatiles          ≤0.5%
Application & Use level:
Use level is 0.2-1% by total weight of formulation, added at the premix stage then coating powder prepared by “one-shot process” is recommended.
Efficiency & Test method:
The coatings powder was prepared by “one-short process” at concentrations of 0.2%,0.3%and 0.5% between Welled EDI and contrastive samples respectively as well as non- additives according to a standard formulation.
Weight each 50g of powder and electrostatic spray it onto the referential panels until the sample was no longer absorbed and baked at proper temperature to form hardened film. Re-weight, whether good powder transfer-efficiency or not was represented by the difference of% of the enhanced weight, the results given as follows:

Important Attention:
It is found that Welled EDI has a tendency of yellowing and quite catalytic activity to shorten gel time of the coating that leads in poorer flow performance. In addition, the slight rising of gloss is observer in some formulations with low gloss.
Packaging:
Packing with PE lined Kraft paper bag.Net weight 25 Kg per bag.
Storage:
Store in dry and cool place to avoid contact other chemicals. Keep away from sunshine and fire.
Toxicity, safety measure:
It is non-flammable and no toxicity is known. Follow usual hygiene practice when handling.
Others:
No condition or warranty is to be assumed from the foregoing information
