Extenders

Extenders are fine white powders or granules that blend seamlessly into paint and coating formulations that contribute to improved scrub resistance, film integrity, and smooth application. They are suitable for architectural, industrial, and protective coatings. 

Alternatives include high-performance functional fillers like wollastonite and talc. Bio-based and low-carbon-footprint extenders are gaining attention. Regulatory guidelines influence the use of specific extenders in eco-labeled or heavy-metal-restricted formulations.
