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 air 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.

Decomet®

Decomet® is SCHLENK’s range of vacuum metallized pigments, in other words those aluminium pigments which are not produced using the classic grinding process, but rather by the removal of an aluminium film from a support upon which it had been deposited by a PVD process. This method gives the pigment particles an extremely smooth surface which reflects light.

Coatings containing this pigment have a glossy metallic appearance and, depending on the composition, are described as having a “chrome effect”, “platinum effect” or “stainless-steel effect”. VMP particles are much thinner than classic aluminium pigments and have better covering power, a fact which needs to be taken into consideration during formulation. Decomet® can be used in conventional, water-based and UV-curing coatings systems.
