Markal 81221 High-temp Paint Stick Marker Yellow

Product Description

The MARKAL 81221 is a high-temperature paint stick marker designed for marking metal and glass surfaces in extreme-heat industrial environments. Rated for use on surfaces ranging from 4000 to 16000 degrees F (2040 to 8710 degrees C), this solid paint stick leaves a visible yellow mark on red-hot and glowing workpieces where conventional markers would instantly fail. The compact stick form requires no solvents, no caps, and no pressurized components. It is used by foundry workers, mill operators, and metal fabricators who need a fast, reliable way to identify or track hot workpieces moving through a production process.

This marker is suited for industrial applications involving coils, billets and bars, castings and pigs, ingots and plates, rails and beams, and glass. It is well matched to steel mills, foundries, forge shops, and glass manufacturing lines where surface temps exceed the range of standard marking tools. The yellow color provides high visibility against darkened or scaled metal surfaces, making it practical for line identification and quality-control tagging in high-throughput environments.

Key Features

• Rated for surface temperatures from 4000 to 16000 degrees F
• Yellow color provides high contrast on dark, scaled, or glowing surfaces
• Solid paint stick format — no ink, no solvents, no pressurized components
• Compatible with coils, billets, bars, castings, ingots, plates, rails, beams, and glass
• Compact size fits easily in a pocket or tool pouch for quick access on the floor

Compatibility

Designed for use on coils, billets and bars, castings and pigs, ingots and plates, rails and beams, and glass surfaces operating at extreme temperatures in industrial production environments.

Installation Notes

This marker is applied by hand directly to the hot workpiece surface — no tools required. Always use appropriate personal protective equipment, including heat-resistant gloves and face protection, when working near red-hot or glowing materials. Follow your facility's lockout and hot-work safety procedures before approaching any high-temperature surface. Do not use near flammable vapors or in enclosed spaces without adequate ventilation.
