    Physical matting agent for exterior powder coatings T-302B

    1.Description

    T-302B is a non-wax containing and resin based matting agent designed for applying in exterior Polyester/TGIC powder coatings to provide low gloss of 10-30% at dosage 2-5%.This chemical system have excellent flow and surface fullness; high DOI suitable for black system; exhibit good stability without obvious various when over baking.

    4.Characteristics:

    ①T-302B combined with different polyester get gloss deviation, normally use polyester has lower reactivity, the finish gloss lower.Eg,( UCB441、 DSM4900、YE-7880、YZ9803、SJ4ET、ZF9336)

    ②Less amount of TGIC could be used,in order to obtain better mechanical properties, normally excess TGIC and T-302B ratio of about 10/1.
