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

2. Characteristics
a a When used as main hardener for epoxy powder coatings, the system can achieve fully cross-linkage at low temperature or expedite curing conditions such as 140a /30min or 240a /30s.
a a As an accelerator, it can reduce curing temperature or shorten curing time of epoxy powder coatings by replacing a part of DICY or substituted DICY in formulas.

3. Use method & levels
a a Premix SA31 with other components of the formula before extrusion.
a a As main hardener, the use level is 6-7 parts/100 parts of epoxy resin (E.E.W 700~900) by weight.
a a As an accelerator, the use level is 0.1 -0.5% based on total weight of formula.

4. Package & Storage
a a Packaging with PE lined fiber drums. Net weight 25kg per drum.
a a Store in cool and dry place to avoid wetting-absorption. Keep package closed after using. Keep away from heat and fire.
