    In recent years, with the enhancement of people's awareness of environmental protection and the heavy regulations and legislation of governments on environmental protection, more and more metal anti-corrosion paint is changing in the direction of environmental protection water-resistant rust prevention. Because of the different habits and applications, there are many kinds of water-resistant rust-proof paint. Common water-based anti-corrosion coatings, water-based metal anti-corrosion paint, water-based anti-rust oil, water-based environmental protection anti-corrosion coatings

    . In addition, according to the surface used to separate, there are water-based steel structure paint, water-based steel pipe paint, water-based transmission paint, water-based equipment paint, water-based hardware paint, water-based bearing rust-proof paint, water-based casting anti-rust paint, water-based car shock absorber anti-rust paint, water-based car radiator rust-proof paint, water-based metal hanger anti-rust paint, water-based automotive parts, substrate anti-rust paint, water-based valve.because water-resistant rust-proof paint is still a relatively new field in China, here is a simple statement on the selection of water-resistant rust-proof paint to consider a few issues.1. Requirements for anti-rust performance of water-based paint:The most common anti-corrosion test indicators are hourly salt spray test results, the selection of water-based anti-rust paint should first find out whether there is a clear salt spray test indicators in the material process requirements, if so, how many hours the indicator is. The project requires low conditions without requiring salt spray test results, which can be as high as several thousand hours.2. Water-like paint requirements for process conditions:content of process conditions can contain more than one content. It mainly includes the composition of coatings, coating methods, film thickness requirements, drying conditions and so on. The composition of a coating refers to whether a two-component coating can be used. Coating methods can include spray, rollers, brushes and other processes. The construction site has no heating and drying equipment, there is no limit to the drying time, is the content of the drying conditions.3. Cost requirements for water-based : This is self-evident, but for water-based coatings the variables are greater than solvent-based coatings. Water-based metal paint because it is in the emerging stage, various technical maturity degree is different, the cost gap is also relatively large, the choice should be considered from the perspective of cost-effective.4. Water-based paint on the requirements of laws and regulations:Because the main thrust of domestic water-based rust-proof paint is still foreign customers, domestic manufacturers in the selection of water-based paint should be included in the volatile organic content (VOC), residual monolith content and other indicators have some understanding, if necessary, should obtain relevant documentation and certificates from suppliers to meet the domestic regulatory requirements of foreign customers.
