By forming an impermeable barrier over the substrate, these pigments prevent direct contact with corrosive agents. While highly effective, their use has waned due to environmental concerns linked to hexavalent chromium compounds. In response, the industry is embracing more eco-friendly alternatives, highlighting the importance of performance and sustainability in tandem.
  3. Phosphate Pigments: Balancing Act – Phosphate pigments, including the resilient zinc phosphate, occupy a unique position, encompassing both barrier and sacrificial protection. Their versatility stems from their ability to establish protective barriers while also offering sacrificial resistance when required. This adaptability makes them a favourite in various applications, from industrial machinery to architectural wonders. Recognizing the significance of these pigments in fortifying coatings, we, as paint raw material suppliers in Delhi, contribute to the preservation of surfaces against the relentless forces of corrosion.
  4. Hybrid Pigments: Synergy of Strengths – Innovation has given rise to hybrid pigments that combine the attributes of various types, aiming for optimised corrosion protection. These hybrids harness the sacrificial properties of zinc-based pigments while incorporating barrier mechanisms, resulting in coatings that offer a multi-layered defence against corrosion’s advances.
  5. Nanostructured Pigments: Future Innovations – The frontier of anti-corrosive pigments expands with the introduction of nanostructured variants. These pigments leverage nanotechnology to provide enhanced barrier and adhesion properties, making them invaluable in challenging environments. Their reduced particle size allows for more uniform distribution within coatings, resulting in enhanced performance and extended service life.
