This green valve-action paint marker produces fast-drying marks that resist wear, weather, and UV exposure across a marking range of -50°F to 150°F (-46°C to 66°C). Its xylene-free, low-corrosion formula is suited to stainless steel, alloy, and superalloy metals where corrosion, pitting, or degradation must be prevented, including welding, oil and gas, aviation, military, and power-generation applications. Low contaminant limits include less than 200 ppm sulfur and total halogens, with individual lot analysis and certification available for reference.
