SN-230, with white powder appearance, is mainly composed of calcium ion-exchanged amorphous silica gel. This new-developed Nanotechnology, without toxic and heavy metal, matches the environmental regulations. It can exchange calcium ions for the paint film and hydrogen ions on the substrate, to neutralize the acidic substances, maintain a high pH value, and prevent the substrate from erosive. Meanwhile, the calcium ions can be combined with the metal oxide film to form a protective layer to protect the steel substrate, reduce corrosion, and prolong the service life. Ion exchange anti-corrosive pigments do not contain heavy metals, toxic, which provides a certain degree of rust protection. USING TIPS: * Recommend dosage is 3%-8%. (Please adjust the dosage according to the actual product.) …
