BY-O-COAT CI 5PW is a bio-based colloidal nano silica, sustainably synthesized from rice husk and designed as a high-performance additive for paints and coatings. With its ultra-fine particle size (≤100 nm) and aqueous dispersion form, CI 5PW easily integrates into waterborne formulations, simplifying processing. It enhances hardness, scratch and abrasion resistance, adhesion, and barrier properties, creating a denser, less porous paint film. By reinforcing the polymer matrix, it significantly improves durability, chemical resistance, and water resistance, resulting in longer-lasting and more resilient coatings.
