Markal 81223 Paint Stick High-temp Surface Marker

Product Description

The MARKAL 81223 is a high-temperature paint stick marker engineered for marking metal and glass surfaces that are heated to extreme temperatures. It applies a visible black mark on red-hot surfaces with a working temperature range of 4000 degrees F to 16000 degrees F (2040 degrees C to 8710 degrees C). The solid paint stick formula bonds on contact, leaving a readable identification mark even at temperatures where conventional inks or labels would instantly fail. This marker is used in foundry, steelmaking, and industrial fabrication environments by tradespeople who need reliable part identification at the forge or furnace line.

This marker is suited for use on coils, billets and bars, castings and pigs, ingots and plates, rails and beams, and glass surfaces. It is designed for industrial and manufacturing settings where hot-surface identification is a routine part of quality control and material tracking. The compact stick format allows workers to apply marks quickly during handling without removing parts from the heat source or waiting for cooling.

Key Features

• Marks surfaces at temperatures from 4000 degrees F to 16000 degrees F
• Black color family for visible contrast on heated metal surfaces
• Solid paint stick format — no ink, no tip, no failure at high heat
• Compatible with coils, billets, bars, castings, ingots, plates, rails, beams, and glass
• Compact, lightweight design at 0.05 pounds for easy handling on the line

Compatibility

Designed for use on hot metal and glass industrial workpieces including coils, billets and bars, castings and pigs, ingots and plates, rails and beams, and glass.

Installation Notes

This marker is a consumable applied by hand — no tools are required. Use appropriate heat-resistant gloves and PPE when working near red-hot or high-temperature surfaces. Follow your facility's hot-work safety procedures and applicable OSHA thermal hazard guidelines. Store unused sticks away from direct heat sources to preserve the paint formulation.
