Non-stick coating dedicated silica sol is a special material used to enhance the performance of non-stick coatings. Its main component is a system of amorphous silica dispersed in aqueous solution. The following is a detailed introduction to it:
- Characteristics
- Small and uniform particle size: The particle size of the silica sol specifically designed for non-stick coatings is usually at the nanometer level, which can be uniformly dispersed in the coating to form a dense film, thereby ensuring the uniformity of the performance of the non-stick coating.
- Low sodium content: To meet the requirements of food contact grade coatings, the dedicated silica sol for non-stick coatings is usually low-sodium silica sol to ensure safety.
- Good stability: It has good chemical stability and storage stability. During storage and use, it is not prone to coagulation or sedimentation, which is convenient for processing and application.
- Its role in non-stick coatings
- Enhancing non-stickiness: Silica sol can form a uniform coating on the surface of objects, filling tiny pores, making the surface smoother, reducing the contact area and friction between food and the surface, and thus effectively reducing the phenomenon of food sticking to the pan.
- Enhancing wear resistance: The silica particles in silica sol can increase the hardness of the coating, making it less likely to be scratched or worn when subjected to friction from kitchenware such as shovels, which helps to extend the service life of the non-stick coating.
- Improving corrosion resistance: The formed coating can act as a barrier to prevent corrosive substances from the outside, such as acidic components in food and moisture, from eroding the base material, protecting the base material and enhancing the corrosion resistance of the non-stick coating.
- Enhance thermal stability: Silica sol coatings can withstand certain high temperatures without decomposition or significant performance degradation. During cooking, even at high temperatures, the stability of the coating can still be maintained, ensuring the long-lasting non-stick performance.
- Application field
- Kitchenware: Widely used in non-stick coatings for kitchenware such as non-stick pans, baking trays, and rice cookers, enhancing their non-stickiness, wear resistance and corrosion resistance, and improving the user experience.
- In the industrial field, the surfaces of some industrial equipment that require non-stick properties, such as food processing equipment and chemical equipment, also use special silica sol for non-stick coatings to prepare non-stick coatings to meet specific production needs.
