Volatile (%) ≥98.0 [GB 1725]

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

 

2.  Characteristics

 Provide lowest 5% (60°) gloss (suggested to choose slow curing polyester, should not be used alone with fast curing polyester).

 Excellent leveling with good mechanical property .

 Good stability for baking, recommended to use in anti-yellowing condition.

 Outstanding gloss stability and reproducibility, satisfy wide ranges of extrusion processing to get below 10% gloss.

 

3.  Use method & levels

 Premix K7215 with other components of the formula before extrusion.

 The use level is 2-6% by weight of total formula, depends on the gloss required. Additional TGIC can enhance mechanical property and stability, ratio for TGIC/K7215 is 1:10 .

4.  Package & Storage

 Packaging with PE lined Kraft paper bags. Net weight 25kg per bag.

 Store in temperature between 2-32℃ or cool dry place to avoid caking.
