    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.
