PRODUCT DETAILS
1. Product Description
This product is a calcium ion-exchanged silica anti-corrosive pigment, a nano ion-exchanged silica anti-corrosive pigment manufactured from an amorphous silica carrier modified with calcium oxide and loaded with calcium ions. As an amorphous silica anti-corrosive pigment, it is a silica-based anti-corrosive pigment and a typical inorganic anti-corrosive pigment, presenting as a white free-flowing powder — a white anti-corrosive pigment. It belongs to the core category of ion-exchanged anti-corrosive pigments; through surface modification it further forms the modified silica anti-corrosion pigment, delivering reliable anti-corrosion functionality for high-end industrial coatings. Free of heavy metals, zinc and phosphorus, it is a heavy metal-free anti-corrosive pigment, a chromate-free anti-corrosive pigment, a zinc-free anti-corrosive pigment, a phosphate-free anti-corrosive pigment and a lead-free anti-corrosive pigment, and a non-toxic eco-friendly, green eco-friendly, environmentally friendly, sustainable, low-VOC, aquatic-safe and safe & healthy anti-corrosive pigment for the green transformation of the coatings industry.
