TAT STG-1 Multipurpose Stamp Ink for Industrial Product Marking

TAT STG-1 Multipurpose Stamp Ink is an oil-based pigment ink developed for permanent and highly adhesive stamping on many non-absorbent and semi-absorbent industrial materials. It is suitable for marking metal, plastic, glass, wood, leather, and other compatible surfaces that cannot be marked reliably with ordinary office stamp-pad ink. The product supports clear identification in manufacturing, warehousing, inspection, packaging, maintenance, and quality-control operations.

The original STG-1 designation refers to the 55 mL small-bottle version of Shachihata’s TAT multipurpose industrial ink. Shachihata’s official product-transition notice identifies STG-1 as a former model and lists the STGA-1 series as its successor. For example, the former black STG-1 is replaced by STGA-1-K, while corresponding replacement codes are available for red, blue, green, purple, and white versions. Buyers should check the current model code and selected color before ordering.

Key Benefits of TAT STG-1 Multipurpose Stamp Ink

TAT STG-1 Multipurpose Stamp Ink provides dependable adhesion on surfaces where conventional water-based ink may bead, wipe away, or produce an unclear impression. Its oil-based pigment composition supports strong color visibility and durable identification when the correct stamp pad, rubber stamp, drying conditions, and substrate preparation are used. The current STGA successor is officially described as a medium-drying industrial ink for non-absorbent and semi-absorbent surfaces.

The compact 55 mL bottle is designed for refilling compatible Shachihata TAT multipurpose stamp pads. This format makes it practical for production lines, inspection stations, workshops, warehouses, packaging areas, and maintenance departments that repeatedly stamp product information. The ink can be used for part numbers, size information, inspection marks, identification codes, batch references, and other industrial markings.

Shachihata lists the current multipurpose formula as compliant with the RoHS Directive. This feature supports manufacturers that need to manage restricted-substance requirements within their marking and identification processes. Compliance requirements can vary by market and production application, so buyers should confirm the current declaration and product documentation for the exact color and model being purchased.

Applications of TAT STG-1 Multipurpose Stamp Ink

TAT STG-1 Multipurpose Stamp Ink can be used for marking components, packaging, production materials, inspection samples, tools, containers, and finished goods. Typical compatible substrates include metal plates, molded plastic parts, glass products, wooden components, leather goods, and other surfaces that have been tested with the ink.

The ink is useful in electronics manufacturing, automotive-component production, hardware processing, appliance assembly, packaging, leather processing, glass production, logistics, and general industrial identification. Actual drying speed and mark durability depend on the substrate, surface coating, contamination, ambient temperature, humidity, ink quantity, stamp design, and handling conditions.

Before production use, test the ink on the actual material. Some plastics, coatings, painted surfaces, flexible materials, or chemically treated substrates may react differently. Testing should evaluate adhesion, drying time, color visibility, resistance to rubbing, and compatibility with any cleaning agents or service chemicals.

How to Use TAT STG-1 Multipurpose Stamp Ink

Shake or mix TAT STG-1 Multipurpose Stamp Ink as directed on the current packaging. Apply a controlled quantity to a compatible TAT multipurpose stamp pad and allow the ink to spread evenly across the pad surface. Avoid excessive filling, as too much ink can produce blurred characters, uneven edges, or unnecessarily long drying times.

Clean the target surface before stamping and remove oil, dust, moisture, release agents, and loose contamination. Press the stamp evenly onto the inked pad, then apply it vertically to the workpiece without sliding. Allow the impression to dry completely before stacking, packaging, wiping, or further processing.

Maintenance of TAT STG-1 Multipurpose Stamp Ink

Shachihata specifies SOL-31A as the compatible solvent for the current STGA multipurpose ink. The solvent can be used to address thickening or hardening of compatible TAT stamp pads and may also assist with cleaning rubber stamps. Use only the recommended quantity and follow the current handling instructions.

Store the bottle tightly closed in a suitable ventilated location and protect it from heat, ignition sources, and unnecessary solvent evaporation. For manufacturers seeking reliable marking on difficult industrial surfaces, TAT STG-1 Multipurpose Stamp Ink provides strong adhesion, multiple color options, convenient refilling, and versatile application across production and inspection processes.
