A brighter, cleaner white, batch after batch.

Snowbrite DB combines TiO2 for opacity, optical brightener (OB) for a brighter-looking white and ultramarine blue (UMB) to offset yellowish tones. All three are pre-blended in the right ratio, so operators weigh a single material.

Suited to products judged by their color, such as ceiling panels, profiles and sheets. We can adjust the blend to your whiteness target and the other pigments in your formulation.

Frequently asked questions

What dosage of Snowbrite DB should I use?

Start at 2–3 phr. The optimum dosage depends on the whiteness target, opacity, and the other pigments and fillers in the formulation, and is confirmed through trials.

Does Snowbrite DB replace TiO2?

Snowbrite DB already contains TiO2, optical brightener and ultramarine blue, so it can replace weighing all three separately. The total TiO2 level still needs checking, especially for outdoor products.
