Curing accelerator for powder coatings Jietonda® SA316 is a special quaternary ammonium compound that can
be used as curing accelerator for powder coatings based on Epoxy,
Epoxy/Polyester hybrid and Polyester/TGIC to improve curing
performance. It may also be used as internal catalyst for carboxyl
terminated polyester resin to provide lower cure temperature or
shorter baking time.
1. Typical properties Appearance | white fine powder | [visual] | Purity (%) | ≥98.5 | |
Herein described to be typical properties and do not constitute
specification limits. 2. Characteristics ● AImpart better catalytic activity and thermal stability when
compared the quaternary ammonium salt compounds now widely used. ● Unlike the quaternary ammonium salt compounds now widely used,
its handling is more easily because this product is free flowing,
non-hygroscopic crystalline solid. 3. Use method & levels ● When used as curing accelerator, SA316 is premixed together
with other components before extrusion. When used as internal
catalyst, SA316 is added into the molten polyester resin in reactor
before discharging. ● The use level is 0.05-0.5% by total weights of formulation. 4. Package & Storage ● Package with PE lined fiber drums. Net weight 20kg per drum. ● Store in temperature between 2-32℃ or cool dry place to avoid
wetting-absorption and caking. Keep package closed after using.
Keep away from heat and fire. ● Based on our experience the shelf life of this product under
above conditions is at least 2 years. |
