How does Six-in-One Leather Wax achieve a one-step pre-painting treatment of six major steps?
Release Time : 2026-01-22
In the industrial coating field, the pre-painting treatment of steel parts is a crucial step determining the coating's adhesion, corrosion resistance, and service life. Traditional processes typically require multiple steps, including degreasing, rust removal, neutralization, surface conditioning, phosphating, and washing. This is not only cumbersome and time-consuming, but also involves multiple tanks and chemical management, resulting in high costs and a large amount of waste liquid. Six-in-One Leather Wax, as an innovative multi-functional pre-treatment agent, successfully condenses the above six steps into a single process through a scientifically integrated chemical formula, significantly improving efficiency. It is particularly suitable for efficient and environmentally friendly pre-painting treatment of large sheet metal parts.
1. Multi-functional Chemical System: One Agent Integrating Six Functions
"Six-in-One Leather Wax" does not actually contain "leather" or "wax." Its name comes from the leather-like, delicate texture and slight hydrophobicity of the treated surface. Its core lies in the synergistic effect of a composite chemical system:
Alkaline components and surfactants simultaneously degrease, emulsify, and remove oil stains;
Weakly acidic corrosion inhibitors and chelating agents gently dissolve surface rust and scale, preventing excessive corrosion of the substrate;
A buffer system automatically neutralizes residual acids and alkalis, stabilizing the pH of the treatment solution;
Titanium/zirconium-based or phosphate components form a dense conversion film in situ on the clean metal surface, providing both surface conditioning and phosphating functions;
Film-forming aids form an ultra-thin organic-inorganic composite layer, providing both short-term rust prevention and enhanced paint adhesion;
A water-soluble carrier allows reaction products to be easily removed with subsequent water rinsing, reducing precipitation.
This integrated "reaction-film formation-self-cleaning" mechanism allows workpieces to proceed directly to the painting process after immersion, spraying, or brushing, requiring only brief draining or light rinsing.
2. Simplified Process: Significantly Improved Production Efficiency
For large sheet metal parts such as large steel structures, engineering machinery shells, containers, or wind turbine towers, traditional multi-tank treatment requires repeated hoisting and transportation, which is time-consuming and prone to secondary pollution. Six-in-one leather wax, however, allows for flexible on-site application: the entire part can be immersed in a single tank, or it can be sprayed over a large area with a spray gun, or even used to repair localized rust areas. The entire process is typically completed within 5–15 minutes, requiring no heating, significantly shortening the cycle time. A case study from a heavy machinery plant shows that pretreatment time was reduced from 2 hours to 20 minutes, increasing production capacity by 300%.
3. Performance Advantages: Less Sedimentation, Longer Lifespan, Stronger Bonding
Traditional phosphating solutions easily produce large amounts of phosphate sludge, requiring frequent tank cleaning; while the six-in-one formula uses low-slag or slag-free technology, resulting in minimal sedimentation. The treatment solution can be recycled for weeks or even months, significantly extending its service life. The resulting conversion film, though thin, has a dense structure and low porosity, forming excellent mechanical and chemical bonding with subsequent epoxy primers or polyurethane topcoats, achieving a cross-cut adhesion rating of 0. Simultaneously, this film provides good short-term rust protection, offering a buffer for storage and transportation before painting.
4. Dual Benefits of Environmental Protection and Economy
The six-in-one process eliminates multiple chemical storage tanks, heating systems, and wastewater treatment units, reducing equipment investment and energy consumption. Because it contains no heavy metals and has low COD/BOD, the difficulty and cost of wastewater treatment are significantly reduced, aligning with green manufacturing trends. Furthermore, operators only need to master the usage of a single agent, resulting in low training costs and minimal safety risks.
Six-in-one leather wax represents a paradigm shift in industrial pretreatment technology from "step-by-step layering" to "functional integration." It uses chemical intelligence to overcome process redundancy, achieving triple optimization of efficiency, cost, and environmental protection while ensuring or even improving coating quality. For modern manufacturing industries that pursue lean production and sustainable development, this "one-step" solution is not only a powerful tool for process upgrading, but also an important step towards green and intelligent manufacturing.
