Opaque Polymer
Opacity Agent / Opacity Modifier
What is Opaque Polymer?
Opaque polymer is a specially designed polymer dispersion used to provide opacity in paint and coating systems. It offers a cost advantage by optimizing the use of titanium dioxide (TiO₂) in the formulation. It imparts film thickness and durability to the paint while also providing high whiteness and opacity thanks to its light-reflecting properties.

In Which Industries Is Opaque Polymer Used?
- Paint and Coating Industry: Reduces costs by decreasing TiO₂ usage in interior and exterior paints.
- Paper Coatings: Used as additives to increase gloss and opacity.
- Plastic and Masterbatch: To reduce color saturation and light transmittance.
- Construction Chemicals: To provide coverage in decorative coatings and filler materials.
How is Opaque Polymer Produced?
Opaque polymers are produced using the emulsion polymerization method. In this process, acrylic monomers are polymerized in the aqueous phase, forming hollow microspheres. The air cavity inside these microspheres scatters light, imparting high opacity and whiteness to the paint film.
Thanks to this technology, the amount of TiO₂ used is reduced, resulting in significant cost savings on paint.
