Silica for Nano Ion-Exchanged Anti-Corrosive Pigments
PRODUCT DETAILS
1. Product Description
This product is silica for nano ion-exchanged anti-corrosive pigments, manufactured from an amorphous silica carrier with nano-scale active sites loaded with calcium ions. As a modified silica anti-corrosion pigment with high specific surface area, it belongs to the core category of ion-exchanged anti-corrosive pigments, presenting as a white free-flowing powder. The nano-scale ion-exchange sites release calcium and silicate ions on demand, forming a dense calcium silicate passivation layer that actively inhibits corrosion at the metal interface. It is a heavy metal-free, chromate-free, zinc-free, phosphate-free and lead-free anti-corrosive pigment — a non-toxic, green, low-VOC and safe & healthy solution for high-end industrial coatings.

3. Application Scope
This anti-corrosive pigment serves as an anti-corrosive pigment for coil coatings, automotive coatings, marine coatings, industrial coatings, aerospace coatings, architectural coatings, appliance coatings, container coatings, bridge & steel structures, pipeline protection, storage tank protection, primers & wash primers, thin-film systems, waterborne coatings, solvent-borne coatings, epoxy resin systems, polyurethane systems and polyester/melamine systems.
4. Manufacturing Advantages
Manufactured by a national high-tech enterprise with a 10,000-ton intelligent production line, this silica for nano ion-exchanged anti-corrosive pigments delivers stable supply and consistent quality. High specific surface area means more active sites per kilogram, i.e., higher efficiency and lower dosage. It is produced by Shandong Zhonglian Chemical Co., Ltd. with a production base in Guangdong; its parent company, Zhongqi (Guangdong) Silicon Materials Co., Ltd. (Stock Code: 880747), is a national high-tech enterprise with over 20 years of dedicated expertise in the silica sector, serving customers worldwide.
5. Shipping & Packaging
Standard Packaging: 25kg moisture-proof woven/valve bags with PE inner liner, customizable. Store in a cool, dry place; non-hazardous chemical supporting global transport.
6. FAQs
Q1: How does nano-scale active sites help?
A: More active sites per kilogram mean faster ion exchange, higher efficiency and lower dosage.
Q2: Is it a filler or a functional pigment?
A: Fully functional — the nano ion-exchange mechanism actively passivates the metal surface.
Q3: Can particle size be customized?
A: Yes, D50 of 3.0–4.0 μm is customizable to match specific formulations.
7. Certifications & Honors
Core certifications and honors: ISO9001:2015, ISO22000:2018, FDA Compliance Certification, FAMI-QS, SEDEX, Food Additive Production License, National High-Tech Enterprise, 17 Patents Certified by the National Intellectual Property Administration of China.
