Coil coatings are the coatings that are applied on metal coils, before these are formed into their final shape. Examples are building panels, garage doors, office furniture, etc.
In coil coatings, the role of mineral fillers is limited due to the low thickness of such coatings. This means that mineral fillers:
- Should have a low particle size distribution;
- Should be chemically inert.
Within Sibelco’s Portaryte range of natural barytes, several products have found their way into the coil coatings’ market.
