Coating plastics
Effect pigments, aluminium pigments, gold bronze pigments, vacuum metallized pigments, polychromatic pigments
Metallic coating effects play an important part in the styling of consumer electronics, e.g. TV casings, HiFi equipment, cameras, computer consoles, mobile phones etc. Mostly, the substrate is plastic, which needs to be taken into consideration when the coating is formulated, keeping in mind adhesive qualities, forced drying, dissolving properties of the solvents, etc.
The required film properties such as tape adhesion, chemical resistance, resistance to detergents, solvents, etc.) make tough demands on the metallic pigments. In critical formulations, pigments with an organic or inorganic coating can act as “problem solvers”. In water-based systems, it is essential to use inhibited pigments.
