OxiGen Photocatalytic
Origen Paints OxiGen Photocatalytic is an air lime-based mineral paint with a matte mineral finish. Free from hydraulic additives and highly vapor-permeable, it is designed to create durable and sustainable surfaces for both interior and exterior applications.
It contains premium artisanal lime sourced from southern Spain, obtained through the natural firing of limestone. Its formulation is enhanced with titanium dioxide nanoparticles (TiO₂), which activate a photocatalytic reaction on the surface when exposed to light.
PHOTOCATALYTIC LIME-BASED MINERAL PAINT
A lime-based mineral paint enhanced with TiO₂: in the presence of light, it breaks down organic deposits on its own finish, helping keep the surface clean. Made with high-quality artisanal lime and highly breathable, with an off-white matte mineral finish for exterior walls and interiors, new construction and repaints.
