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.

Grandal®

Grandal® pigments are granulated, pellet-shaped, solvent-free, leafing and non-leafing aluminium pigments containing urea-aldehyde-resin binders.

They are easy to dose and, due to the pre-wetting with a universally compatible binder, are also very easy to disperse.

D 50 value [µm] Metal content [%] Solvent Application
Grandal 2600 24 approx. 95 urea-aldehyde resin
Grandal 1700 18 approx. 95 urea-aldehyde resin
Grandal 2900 11 approx. 95 urea-aldehyde resin
