JB/T 7456-1994 "Technical conditions for painting unsaturated polyester putty for machine tools" is the machinery industry standard, which stipulates the painting technical requirements of unsaturated polyester putty for machine tools. The content includes the composition and classification of putty, technical indicators (such as scraping, drying time, sanding, adhesion, corrosion resistance, etc.), coating process (substrate pretreatment, putty preparation, coating and curing process), inspection methods and quality control rules. This standard is suitable for unsaturated polyester putty painting that fills surface defects and improves flatness in machine tool manufacturing, provides technical basis for standardizing putty performance and coating process, helps to improve the surface painting mass of machine tools, guarantees the flatness and corrosion resistance of workpieces, and meets the accuracy and protection requirements of machining.
