With environmental concerns and environmental regulations, more and more coating manufacturers are trying to replace heavy metal pigments containing chromium with non-toxic and environmentally friendly anti-corrosive pigments in coil coatings and general industrial coatings. At present, this chromium-free process is significantly accelerated, and the "GB 30981 limit of harmful substances for industrial protective coatings" also clearly stipulates that the limit value of hexavalent chromium is less than 1000ppm.
In the face of this environmental pressure challenge, foreign raw material manufacturers as early as the 1980s began to invest in the research of silica anti-corrosive pigments. Domestic "Paint Industry" in 1994 the 4th also published Shantou University on calcium ion-exchanged anti-corrosive pigment research paper. But the real industrialization of the company only a few foreign giants. Through independent innovation and research and development, Lingwe Technology has broken foreign monopoly and launched its own patented products of ion-exchanged silica anti-corrosive pigment.
Customer Demand
Free of chromium and other heavy metal elements.
Universal for water-based and solvent-based.
Can be ground with other types of anti-corrosive pigments or fillers.
It can reduce the foaming and permeability of the paint film.
Recommended
HOMAC?LM50
Highly efficient anti-corrosive performance, silica anti-corrosive pigments have the characteristics of low aperture and high ratio, and can adsorb hydrogen ions on the surface of the paint film; The surface passivation layer of silicate can be further formed, which can effectively reduce the foaming property and permeability of the paint film. Calcium ion-exchanged silica anti-corrosive pigment can improve the surface density of silicate and ensure long-term anti-corrosion performance;
Completely green, free of any heavy metals and zinc; It does not contain phosphorus, and the water ecology is non-toxic, meeting the "GB 30981-2020 Limit of harmful substances in Industrial Coatings" and "GB/T 3560-2-2017 Green Product Evaluation";
Universal for water-based and solvent-based, and it can be combined with other types of anti-corrosive pigments to have a synergistic anti-corrosion effect;
