Documentation of the classic industrial ink and polish suspension. This formula focuses on substrate penetration, pigment load, and weather resistance via wax-resin encapsulation, replicating the vintage solvent-heavy bite.
01.Solvent Preparation: Decant naphtha into a glass vessel. If heating to increase solubility, use a water bath (double boiler) exclusively. Ensure zero proximity to ignition sources.
02.Binder Integration: Add wax to the solvent. Stir until the solution is clear and the wax is fully dissolved.
03.Pigment Loading: Gradually introduce Nigrosin powder. Agitate continuously to prevent clumping. The high solvent-to-dye ratio ensures deep staining capability.
04.Stabilization: Incorporate oleic acid. This prevents the mixture from separating during long-term storage in the applicator.
05.Filtration: Pass the final liquid through a fine-mesh filter to remove undissolved particulates that may obstruct the dauber or valve.
Technical Characteristics
Surface Interaction: Low surface tension allows for deep penetration into porous substrates (concrete, brick, leather).
Buff Resistance: High. The wax acts as a mechanical barrier against water-based cleaning agents, while the dye stains the material structure.
Finish: High-gloss black with a slight bluish undertone.
FLAMMABILITY HAZARD: High vapor pressure solvent. Handle under forced ventilation or within a fume hood. Utilize appropriate chemical-resistant PPE.
