ITW Dykem UV-Marker 91195 (clear) 48 Units/Case

ITW Dykem UV‑Marker 91195 is a valve-action invisible UV fluorescent industrial marker. Its marks are nearly transparent under normal light and glow bright blue when illuminated by UV black light. Designed for covert anti-counterfeiting and hidden QC marking, it creates invisible identification for anti-tamper checks, quality traceability and asset control on non-porous surfaces including metal, plastic and glass.

Dual invisible & UV fluorescent property: The coating is clear and nearly undetectable to the naked eye, yet instantly reveals a distinct blue mark under UV light, delivering excellent concealment and visibility.

Wide compatibility with non-porous surfaces: Adheres firmly to plastic, glass, metal and most smooth non-porous surfaces without altering the appearance or performance of the substrate.

Fast drying: Formulated for quick drying, surface dry within 45 seconds to 1 minute after application, greatly reducing waiting time and accidental smudging during production.

Excellent chemical resistance: Cured marks offer superior solvent resistance and withstand gasoline, motor oil and common petroleum solvents, keeping marks intact in harsh industrial environments.

Reliable valve-action ink feed: Medium fiber tip paired with valve design ensures consistent, even ink flow. It effectively prevents tip dry-out even when the cap is left off for extended periods.

Typical application areas: Security, anti-counterfeiting & tamper evidence: Widely used for covert marking on high-value goods, electronic components and confidential documents as a reliable tamper-check measure. Unauthorized personnel cannot easily detect or replicate the marks. Quality Control (QC) & concealed inspection: Inspectors apply invisible marks on designated areas to track production batches, inspection status or rework records, while preserving the finished product’s aesthetic. Asset & component management: For internal covert ownership marking of factory tools, molds and precision parts to prevent loss and misidentification.
