Marker Sakura Solid orange fluorescent — high-temperature resistant, model SKXSC305RT

Sakura Solid orange fluorescent marker model SKXSC305RT is a high-temperature resistant marking pen designed to create permanent, highly visible marks on surfaces exposed to heat. The fluorescent orange pigment enhances visibility in varied lighting conditions, while the solidified ink formulation resists smear and fading when applied to metals, ceramics, glass and heat-treated components. The marker is intended for industrial and workshop environments where durable, heat-stable identification is required.

Advantages

The solid, high-temperature ink delivers long-lasting, permanent markings that withstand elevated temperatures and resist solvent contact and abrasion better than conventional water-based markers. Fluorescent orange color provides improved contrast against dark and metallic surfaces, supporting quick visual identification. The tubular solid tip ensures consistent line width and reduced dripping, minimizing contamination and waste during marking operations.

Suitable for

• Marking metal parts before heat treatment, welding or machining
• Labeling ceramic and glass components that experience elevated temperatures
• Permanent identification of tools, dies and fixtures in industrial workshops
• Laboratory sample coding where heat resistance and visibility are required

Key specifications

• Color: fluorescent orange for high visibility
• Tip: solid tubular tip for stable line and reduced dripping
• Ink type: high-temperature resistant solid ink formulated for permanence
• Suitable surfaces: metals, ceramics, glass and heat-treated parts
• Durability: resistant to heat, abrasion and common solvents encountered in workshops

How to use

Ensure the surface is clean, dry and free of loose debris, oil or heavy contaminants before marking. Press the solid tip gently to start the ink flow and apply steady pressure to draw the mark. For best results on rough or oxidized metal, make several passes if necessary. Allow the ink to set; the solid formulation reduces smearing so marked parts can be handled shortly after application. Close the cap immediately after use to prevent contamination and drying of the tip.

Usage recommendations

Store the marker upright with the cap closed and away from direct heat sources. Test on a small, inconspicuous area prior to use to confirm adhesion and visibility on the specific substrate. Use appropriate personal protective equipment when marking hot or chemically treated parts, and follow workplace safety guidelines for ventilation and handling.
