Product Description

1、 Product Introduction: The independent technology is the first of its kind to use phytic acid derived metal super chelating agents to form a dense and stable chemical conversion film on the surface of steel and aluminum. This material does not contain harmful pollutants such as heavy metals and sodium nitrite, and does not require surface mixing or rust prevention sealing. It does not produce solid slag or waste liquid such as phosphate, and can fully replace traditional phosphating to achieve clean and environmentally friendly pre-treatment production. The film layer is dense and firm, with excellent anti rust effect and coating resin bonding strength. The anti rust and external coating adhesion indicators between processes far exceed those of silane ceramic materials. High film formation efficiency, low usage consumption, and significantly reduced user costs. This technology has been granted three national invention patents and has been evaluated as an international advanced level by renowned experts in the corrosion industry. In 2018, it won the third prize of Qingdao Science and Technology Progress Award. 2、 Product Features: Wide application range: It can be used for pre-treatment and passivation rust prevention of various metal surfaces such as steel and cast iron parts, special steel, aluminum alloys, galvanized and tin plated sheets, non-ferrous metals, etc. Excellent product performance: particularly strong rust prevention performance, super strong rust prevention between processes. The external coating has excellent adhesion and all indicators meet or exceed traditional phosphating. Low cost of use: The cost of using chemicals can be significantly reduced by more than 30% compared to silane ceramicization, and by 10-20% compared to zinc based phosphating. Green and environmentally friendly: free of heavy metals and sodium nitrite, no need for surface mixing or sealing, no need for frequent slag cleaning and tank replacement, simple and low-cost discharge water treatment. Ø Used at room temperature, no need for pure water Ø Easy to operate and labor-saving 3、 Indicator data (steel surface): 1. Bare film indicators: (1) Neutral salt spray test: No rust on the cold plate after 45 minutes, exceeding the zinc phosphating standard (2) Daily rust prevention time: no rust for more than 7 days in summer and more than 30 days in winter 2. Paint film indicators: (1) 1mm spacing grid test: 0-1 level (2) 50Kg heavy hammer impact test: no cracks on both sides (3) Neutral salt spray test: Cross cut damage test for 400 hours, with rust spreading on both sides of the marked line not exceeding 0.5mm; No rust, bulging, or peeling of the paint film was observed after 800 hours of non scratch and fork damage test.
