【Important Attention】
Don’t mix other curing agent with Xinjia HB31 for its highly reactive characteristics. The result of mixing will alter the coating’s surface tension and consequently a poor light and bad surface are unavoidable.
In the process of making powder coatings, put together epoxy resin, fillers and Xinjia HB31 when they are dry. Fully mix them in an proper extruder with the extruding temperature below or at 100℃.The time they stay in the extruder should be short to avoid cross linking ahead of time. The extruder should be cooled down without delay to avoid unnecessary chemical reaction.
【Packaging】

【Storage】
Store in dry and cool place to avoid contact other chemicals. Keep away from sunshine and fire.
【Toxicity, safety measures】
