For corrosion prevention of aluminum die castings. Can be processed in a short time and at low temperatures, reducing energy costs.
The high corrosion-resistant sealing agent "5E161" is a sealing treatment agent that achieves high corrosion resistance even for die-cast materials like ADC12, which are difficult to impart corrosion resistance. During sealing, metal hydroxides co-precipitate with aluminum fluoride, filling and sealing the deep pores (approximately 3μm) and also precipitating the chemical components on the surface to form an anodized layer with high corrosion resistance. It can be processed at a low temperature of about 40°C, and the processing time is short at about 3 minutes, allowing for reduced energy costs and improved work efficiency. 【Features】 - In salt spray tests on ADC12 material, only a slight amount of rust appeared even after 1200 hours. - Numerous achievements in processing aluminum die-cast and castings requiring corrosion resistance. - Improved productivity due to low-temperature, short-time processing. *For more details, please refer to the downloadable materials.
