Benzoin is to eliminate the bubbles in the melting powder coating, i.e. eliminate the key factor resulting in film pinhole.It can be applied in all categories of powder coating.Application method: mix with other ingredients directly before extrusion.The recommended dosage is about 0.3~0.8% calculated on total formulation weight. The precise amount shall be based on the lab test.Its dosage should be properly controlled to obtain suitable film, as superfluous Benzoin may cause yellowing phenomenon.

Formulation Provided (our advantage):
Some customers are worried their final products if can get best result, we have our own formulator (Engineer for powder coating formulation) who is testing and updating the formulation according to customer requirement all the time. And have very good experience for the formulation to support customer to make different effect powder coatings.
We can supply customer all raw materials in the formulation, including polyester resin, epoxy resin, barium sulfate and so on.
We also have more than 30 years experience in pruducing powder coating mixer, extruder machine, cooling belt and grinding mill system.
