Technical Specification:

  • Engineered for permanent marking on multi-surface substrates including cellulose (paper), ferrous/non-ferrous metals, stone, elastomers, thermoplastics, and glass.
  • High-pigment, opaque ink system delivers vivid chroma intensity with uniform optical density and smooth film deposition.
  • Equipped with a 4.5 mm bullet-type acrylic nib enabling controlled ink delivery for bold, uniform stroke.
  • Cylindrical body profile of approximately 140 mm length ensures optimized grip comfort and precise line control during extended operation.
  • Ink exhibits hydrophobic characteristics providing high durability against moisture, smudging, and solvent exposure.
  • Non-toxic, xylene-, benzene-, and toluene-free formulation; conforms to REACH and EN71 safety standards for safe domestic and industrial usage.
  • Suitable for artistic rendering, fabrication marking, component coding, and general industrial or hobby-grade applications.
  • Low-odor, controlled-evaporation solvent system ensures reduced vapor emission and operator comfort.
  • Permanent ink film exhibits high abrasion, rub, and light resistance — maintaining legibility under mechanical and environmental stress.

FAQs:

Q 1. What type of ink formulation is used in the Paint Marker?

A. The marker uses an oil-based, pigment-dispersed ink system with high opacity and excellent adhesion properties, designed for permanent, industrial-grade marking on multiple substrates.

Q 2. How fast does the ink dry on smooth surfaces like metal or glass?

A. The ink exhibits rapid solvent evaporation, achieving surface dryness in less than 20 seconds on non-porous substrates such as metal, glass, and ceramics.

Q 3. Is the ink water-resistant and suitable for outdoor applications?

A. Yes. The ink forms a hydrophobic, weather-resistant film that maintains colour intensity and adhesion under exposure to water, sunlight, and environmental stress.

Q 4. Can the marker be used on high-temperature or industrial surfaces?

A. Yes. The ink maintains thermal stability and adhesion up to 50°C, as verified by oven tests over 15 days without degradation or pigment migration.

Q 5. Is the Paint Marker safe for regular or indoor use?

A. Absolutely. The formulation is xylene-, benzene-, and toluene-free, low in odor, and complies with REACH and EN71 safety standards, making it safe for both professional and domestic environments.
