Low temperature curing agent for epoxy powder coatings

Jietonda® K7101 is a low temperature curing agent for epoxy, which is especially designed for preparing various low temperature cure decorative powders or fast curing functional powders. Because of its good reactivity and catalytic activity, it can be used both as a sole curative and as an accelerator for other epoxy hardeners, such as DICY.

1. Typical properties

Herein described to be typical properties and do not constitute specification limits.

2. Characteristics
　 ● As a sole curative of epoxy powders, it can make the system fully cross link at low temperature or expedite curing conditions such as 120℃/30min or 240℃/30s.
　 ● As an accelerator, it can reduce curing temperature or shorten curing time of epoxy powders by combining with other epoxy hardeners, such as DICY.
　 ● Widely and excellent compatibility with epoxy resins impart smooth and flat surface to the film.
　 ● Good reactivity and catalytic activity at curing temperatures impart excellent mechanical properties to the film.
　 ● Good storage stability.

3. Use method & levels
　 ● Premix K7101 with other components of the formula before extrusion.
　 ● As sole curative, the use level is 2-4 parts/100 parts of epoxy resin (E.E.W 700~900) by weight.
　 ● As an accelerator, the use level can be flexibly adjusted according to the kind and levels of the main curing agent.

4. Package & Storage
　 ● Packaging with PE lined fiber drums. Net weight 20kg per drum.
　 ● Store in temperature below 25℃ or cool dry place to avoid wetting-absorption. Keep away from heat and fire.
　 ● The shelf life of K7101 is at least 1 year when stored under above conditions.

5. Advisement
　 ● To keep the storage stability,coating powders formulated by K7101 should be stored below 25℃ or cool dry place and avoid wetting-absorption.
