Introduction to ZS-522 High Temperature Resistant Non stick Coating and Application Instructions for Molds

1、 Introduction to ZS-522 High Temperature Resistant Non stick Coating（New application of high temperature mold metal non stick self-cleaning coating）

（1） Product Overview

ZS-522 high temperature self-cleaning non stick coating is a special functional coating developed by Beijing Zhisheng Weihua Chemical Co., Ltd. to address the pain point of equipment being easily adhered by molten metal and slag under high temperature conditions in industries such as metallurgy and smelting. The company has invested a lot of research and development efforts in this area. This coating belongs to pure inorganic functional coatings, and its core advantage lies in its anti sticking and self-cleaning performance in high-temperature environments. It can effectively isolate the contact between high-temperature metal liquids, slag, and equipment substrates, avoiding adhesion phenomena. At the same time, it has excellent high temperature resistance, corrosion resistance, and mechanical stability, which can significantly improve the service life of high-temperature equipment and reduce the operation and maintenance costs of enterprises.

（2） Core components

The coating adopts a high-temperature resistant inorganic silicate modified solution specially formulated by Zhisheng Weihua, mixed with sodium lignosulfonate solution as the film-forming material, supplemented with high-quality fillers such as nano graphite flakes, silicon carbide, boron carbide, etc. It is processed through multiple precision processes such as nano ultrasonic dispersion and high-temperature synthesis. Its formula system does not contain any organic materials, ensuring no volatilization or odor in high-temperature environments from the source, and will not have any impact on the purity of the smelted metal. It is both safe and environmentally friendly.

（3） Key Performance

The performance indicators of ZS-522 high-temperature resistant non stick coating are at a high level in the industry. After testing and verification, the core performance is as follows:

High temperature resistance: Long term temperature resistance can reach 2000 ℃. After repeated thermal shock in the range of 1500 ℃ to room temperature for 100 times, the coating does not crack or peel off, and can adapt to severe temperature changes in high-temperature conditions;
Anti sticking and self-cleaning properties: The surface energy of the coating is ≤ 0.03N/m, with high surface tension and low friction coefficient. It has repulsive force against high-temperature molten metals such as steel, iron, aluminum, and various types of slag, and is easy to clean even with a small amount of adhesion;
Mechanical stability: The coating hardness is ≥ 6H (Mohs), the adhesion force reaches level 1 (grid cut method), the elastic modulus is 1 × 10 ⁵/Mpa, and it has excellent impact resistance and wear resistance, which can resist the erosion of high-temperature molten materials;
Chemical stability: Excellent resistance to aging and corrosion, able to withstand corrosion from acid and alkali vapors at high temperatures, with no significant changes observed after 1000 hours of photothermal aging test;
Thermal conductivity: The thermal conductivity coefficient reaches 120 W/m.K, and the thermal expansion coefficient is 13 × 10 ⁻⁶/℃, which can quickly conduct heat and avoid damage to the coating or substrate caused by local overheating.

（4） Applicable fields

This coating has a wide range of applications and is mainly used on the surfaces of various production equipment and instruments that come into contact with high-temperature metal melts and slag, including steel ladles, metallurgical furnaces, metal casting channels, electrolytic aluminum slag shovels, oxygen spraying pipe outer walls, and protection of various high-temperature metal processing equipment. At the same time, it can also be used in scenarios such as laser cutting trays and kiln walls that require high-temperature anti sticking protection.

2、 The use of ZS-522 high-temperature resistant non stick coating on molds（New application of high temperature mold metal non stick self-cleaning coating）

（1） Applicable mold types

Based on the performance characteristics of coatings, their application in the field of molds mainly focuses on high-temperature metal forming molds, including copper refining steel molds, aluminum alloy production molds, zinc refining molds, and other types of molds that come into direct contact with high-temperature metal melts. Under normal working conditions, this type of mold is prone to melt infiltration and sticking due to the strong affinity between the molten metal and the mold substrate, which seriously affects product quality and production efficiency. ZS-522 coating can accurately solve this core problem.

（2） Basic usage method

The coating is easy to apply and does not require complex equipment. The specific operation process is as follows:

Substrate pretreatment: Polish, degrease, and rust the surface of the mold to ensure it is dry, clean, and free of impurities, and to enhance the adhesion between the coating and the substrate;
Coating construction: Spraying or brushing can be used for construction, and the construction environment temperature should be controlled at 30-60 ℃. It is recommended to apply more than 2 coats to ensure that the coating thickness is ≥ 0.1 mm and the protective effect is guaranteed;
Curing molding: Adopting room temperature self curing method, no additional heating or baking is required. After construction, it can be naturally cured and put into use. The coating is solid and firm after curing, with good air tightness.

（3） Core application advantages

After applying ZS-522 high-temperature resistant non stick coating on the surface of the mold, it can bring multiple practical values:

Eliminating the hidden danger of mold sticking: The coating can effectively block the contact between high-temperature molten metal and the mold substrate, fundamentally solving the problem of mold sticking and avoiding product scrap and mold damage caused by mold sticking;
Extend mold life: The coating can resist the erosion and scouring of high-temperature molten liquid and slag, reduce mold wear and thermal fatigue damage, and significantly extend the service life of the mold;
Improve production efficiency: No need for frequent downtime to clean the adhesive on the surface of the mold, reducing cleaning time and labor costs, while ensuring consistency in product molding and improving production continuity;
Reduce comprehensive costs: Reduce mold maintenance, replacement costs, and product scrap rates, and ensure stable use of the coating for 20-50 days (depending on the specific working conditions) after one application, significantly reducing operation and maintenance costs.
