Talc

Choosing the right mineral filler affects paint performance, durability, and cost. This technical guide compares dolomite and calcium carbonate across hardness, weather resistance, particle size, loading levels, and cost-performance trade-offs. Whether you are formulating an exterior masonry coat or an economy interior emulsion, find out which filler suits your application and when blending both makes the most sense.

Learn how mesh size, micron grading and particle size distribution affect mineral filler performance in paints, plastics and construction. Guidance from Omega Fine Products.

Mineral fillers are fundamental to paint formulation, influencing opacity, rheology, scrub resistance, durability and overall cost efficiency. In this technical overview, we examine how calcium carbonate, dolomite, silica and talc contribute to coating performance, and how properties such as particle size distribution, mineral hardness, oil absorption and dispersion behaviour determine final film quality.
