Powder coatings stabilizers

Other potential applications are ceramic powders coated with their sintering aids, zirconia coated withyttria stabilizer, tungsten carbide coated with cobalt, or nickel, alumina abrasive powders coated with a relatively brittle second phase such as MgAl204 and plasma spray powders without the segregation of alloying elements. 

The mono- and disubstituted organotins considered here are used as stabilizers in PVC or as catalysts for the production of electrodeposited coatings (mainly in motor vehicle primers), sihcone rubbers, esterification and powder coatings, and polyurethanes, as well as for coating glass. 

The mesophases formed by liquid crystalline (LC) polymers are well known to impart strength, toughness, and thermal stability to plastics and fibers (1-5). While LC polymers have been widely studied, their potential utility as coatings binders seems to have been overlooked. Among the very few reports that may describe LC polymers in coatings are patents claiming that -hydroxybenzoic acid (PHBA), a monomer commonly used in LC polymers, enhances the properties of polyester powder coatings (6-9). 

Additive for liquid and powder coating formulations (less brittle, self-levelling, high/low T stability, scratch and mb resistance, transparency, sur ce effects above)... 

Polyphenols. Polyphenols react with epoxy resins on heating, but require an accelerator (e.g., tertiary amines, imidazoles). On account of their low color stability, powder coatings based on this combination are not used for decorative purposes, but exclusively for functional purposes where high thermal, mechanical, and chemical resistance is required (e.g., pipe coatings). 

Stringent coating stability requirements on metal surfaces can be met by using powder coatings. Use of powder coatings is therefore increasing in new areas of application (e.g., for the colored coating of sanitary ware [12.2] and corrosion protection of truck tanks [12.3]). 

Bronze pigments, silane coated (Resist type) PVC, powder coating, thermoplastic resins, thermosetting resins Improved heat and storage stability better resin compatibility... 

Nylon 12 Thermoplastic polymer of lauric lactam. Has good impact strength, hardness, abrasion resistance, and dimensional stability. Processed by powder coating, rotational molding, extrusion, and injection molding. Used in sporting goods and auto parts. 

Polyvinyl Chloride Thermoplastic polymer of vinyl chloride, available in rigid and flexible forms. Has good dimensional stability, fire resistance, and weatherability, but decreased heat and solvent resistance and high density. Processed by injection and blow-molding, calendering, extrusion, and powder coating. Used in films, fabric coatings, wire insulation, toys, bottles, and pipes. Also called PVC.
