How to boost paint opacity, reduce TiO₂ and improve sustainability with Elementis' opacity toolbox

Formulators today face increasing pressure to achieve high opacity, lower environmental impact, and reduced formulation costs—while contending with the rising price and performance variability of TiO₂. Achieving one coat hide and consistent spreading efficiency often requires trade offs between quality and affordability, making it difficult to meet both customer expectations and sustainability goals.
In this webinar, Elementis experts will introduce the Additive Opacity Toolbox, a modular and highly efficient set of additives engineered to enhance hiding power, improve film build, and significantly reduce TiO₂ demand. By optimizing TiO₂ spacing, film thickness, and application properties, this toolbox allows formulators to achieve up to 25% higher spread rate, 15% TiO₂ reduction, and reductions in CO₂ footprint, all without compromising performance.
Attendees will gain a practical understanding of how different additive combinations can be tailored to architectural paint systems to improve opacity, application feel, and overall cost in use. Whether you aim to boost one coat hide, formulate more sustainably, or increase profitability, this session will provide clear strategies to rethink opacity performance.
