HEAT RESISTANT POWDER COATINGS

摘要

The invention provides a melt-blendable, film-forming, thermosetting, powder coating composition for producing a high temperature resistant coating, the composition is particularly useful for coating substrates subjected to high temperatures, such as, boilers, ovens, furnaces, stove burners, steam lines, heat exchangers, barbeque equipment, cooking utensils, he powder coating composition comprises A) at least one polysiloxane resin, and B) 0.01 to 50 parts by weight (pbw) based on 100 pbw binder of at least one inorganic anhydrous borate based on at least one alkali metal.
