Polyester resins for powder coatings are mostly saturated

Powder coatings are weather-resistant polyester powder coatings. Most polyester resins used are saturated. According to their structure, terminal groups can be divided into terminal carboxyl groups and terminal hydroxyl groups. Powder coating for aluminum profiles uses powder coating, and electrosta... read more

It does not contain toxic, solvent and volatile toxic substances, and fully meets the requirements of the Environm... read more

Selection of raw material additives for producing powder coatings

In principle, the additive used for powder coating must be solid. If the additive is a solid material with extremely low viscosity or melting point, when the additive amount exceeds 2%, it has poor storage stability in summer and is easy to caking. Therefore, the choice of auxiliaries is very limite... read more

Its application and construction area have been expanding year by year, and the construction market prospect in China is very broad. Let's f... read more

How to prevent agglomeration of powder coatings

Powder coatings are prone to agglomeration at certain temperatures, mainly due to the softening of the resin and the role of leveling agents in the coating. A thermosetting coating is a low molecular weight organic polymer resin. So how to prevent it from agglomerating in the work? Let's follow it b... read more
