Decorative Paints
Fillers that support opacity, finish and application properties in architectural paints.
Overview
Decorative paints for walls and buildings contain a high proportion of mineral fillers. The fillers affect coverage, application and the appearance of the dried film.
Cost matters in these formulations, and filler choice has a large effect on it.
Formulation challenges
- Opacity and coverage
- Fillers can support the hiding power of the white pigment when their particle size is well chosen.
- Finish
- Matt, satin and other finishes depend partly on the fillers’ particle size and shape.
- Application
- Flow, brushability and scrub resistance are influenced by the filler package.
The role of mineral fillers
- Calcium carbonate
- Widely used as an extender in decorative paints, in both fine and coarse grades.
- Kaolin
- Its platy particles can contribute to matting and film properties.
- Combined fillers
- Blends of minerals can be adjusted to a target finish and cost.
