Description

Powder, like any coating material, must be shipped, inventoried, and handled in its journey from the powder-coating manufacturer to the point of application. Manufacturers’ recommendations, procedures, and cautions should be followed. Although various powders may have specific requirements, some universal rules apply. It is important that powders always be protected from: excessive heat; humidity and water; and contamination with foreign materials, such as other powders, dust, dirt, etc. Water and powder do not mix when the intent is to spray as a dry powder. Exposure to excessive humidity can cause the powder to absorb either surface or bulk moisture. Because powder coating is a dry process, contamination by dust or other powders cannot be removed by filtering, as it can with liquid paint. It is imperative, therefore, that all containers be closed and protected from grinding dusts, aerosol sprays, etc. Powder coatings contain polymers, curing agents, pigments, and fillers that require safe handling procedures and conditions.
