Permanent TAT Ink for Autostamps
Shachihata TAT Ink is a premium permanent indelible ink manufactured in Japan, specifically engineered for use with Shachihata autostamps and TAT stamp pads in industrial marking applications. Unlike conventional office inks that are suited only to porous paper surfaces, TAT Ink uses an advanced oil-based dye formulation containing ultra-fine pigment particles, enabling it to adhere firmly and permanently to both porous and non-porous surfaces — including metal, plastic, glass, rubber, ceramic, leather, and coated paper.
TAT Ink is widely trusted across manufacturing, automotive, electronics, metal processing, and logistics industries for product identification, batch and lot number marking, inspection coding, and traceability documentation. Once dry, impressions made with TAT Ink exhibit exceptional resistance to water, oil, heat, light, resin, and chemical exposure — making them suitable for components and products that undergo further processing, cleaning, or exposure to harsh industrial environments after marking.

Key Performance Properties
- Oil-based formulation with ultra-fine pigment particles ensures firm, permanent adhesion on non-porous surfaces where conventional water-based inks fail to bond.
- Strong marking with excellent smear resistance — impressions dry to a permanent finish that remains clear and legible under repeated handling.
- Proven resistance to water, oil, heat, light, resin, and chemical exposure, making TAT Ink suitable for components that undergo further processing or field exposure after marking.
- Available in both regular dry (5–10 minutes) and quick dry (1–5 minutes) formulations to suit production line speed and surface type requirements.
- Compliant with RoHS, the ELV Directive, and Ozone Layer Protection regulations, confirming that TAT Ink does not contain environmentally prohibited substances.
- Refill bottles in 55 ml and 330 ml sizes ensure cost-effective, long-term ink supply for both low-frequency and high-volume industrial marking operations.
Typical Industrial Applications
TAT Ink is used across a broad range of manufacturing and industrial sectors. In metalworking and machining, it is used for part number identification, inspection coding, and lot number marking on steel, aluminium, and stainless steel components. In automotive manufacturing, it marks motor parts, chassis components, and pipe assemblies that must remain legible through assembly and subsequent processing.
In electronics manufacturing, TAT Plastic Ink is used for lot number marking on circuit boards, epoxy resin components, and plastic housings. In glass and ceramics production, it provides permanent lot and quality marks on finished products. Across logistics and warehousing, it enables clear, durable marking on packaging, crates, and labels that must withstand transit and storage conditions.
