Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as "whiteware," aluminium extrusions, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods. R7333 is used in the production of gloss reduced powder coatings of all ratios of hybrid system. Gloss level ranging from 15-80% may easily be formulated by the use of P7333. Coatings used with R7333 are characterized by color and gloss stability under over-bake conditions. 1. Appearance: yellowish powder
2. Sieving analysis: Min. 95.0% passing 53 um
3. Usage: ~12 PHR ( Part per hundred resin)
4. Cure schedule: 200℃ x 14 Min. (Metal Temperature)
