Sakura Solid Glow-In-the-Dark Paint Markers - Permanent Marker Paint Pens - Window, Wood, & Glass Marker - Glow In the Dark Paint - 1 Pack

The first marker of its kind to incorporate safety grade photoluminescent material for easy Glow-In-The-Dark safety applications. It can write on, stay on, and glow on smooth, rough, wet or damp surfaces. Photoluminescent pigments are better than novelty grade-because they glow brighter after the same light exposure. The brightness and the duration of the glow mark can be up to 30 minutes, but is dependent upon four factors: a) the intensity of the light/energy source the mark is exposed to, b) the distance of the light/energy, c) the duration of time which the mark is exposed, d) and the paint thickness of the mark.Possible applications include those for safety, aerospace, commercial fishing boats, fire stations, mining, search and rescue, automotive sales, construction sites, highway construction, shipping, warehouses, and more. The 13mm wide stick can be trimmed with a knife for smaller marks. Working temperature of 15°F to 248°F (-10°C to 120°C). The twist-up base easily advances the solidified paint and the secure cap keeps the paint marker ready to use. Meets ASTM E2072-02 Luminance Standard. Avoid use on acidic surfaces lower than a pH of 2.0. Alcohol based cleaners will remove ink from most non-porous surfaces. Water resistant on most surfaces. Dries within 10 minutes. SDS sheets are available upon request.Since the 1970s, Sakura has been developing markers and pens for use in industrial environments.
