The new improved Montana NIGHTGLOW NG1000, is a high pressure, high-grade nitro-acrylic based paint. It now contains higher light emitting, luminescent pigments. The new quality stores light as absorbed energy charged and emits that energy (as light), when in total darkness. The now even longer lasting luminescent green color, glows in the dark. The time the paint emits light varies subject to the intensity and length of exposure to light (charging) and amount of NIGHTGLOW EFFECT paint applied. For optimal glow, it is recommended to apply multiple layers on pre-primed substrates. The highest emission of light occurs immediately after charging. Can be used for indoor and outdoor applications. For best results, use a strong light source to load the NIGHTGLOW EFFECT spray and view in complete darkness without other light sources. NIGHTGLOW can be used on smooth, rough and primed surfaces like metal, wood, hard plastics, primed carton and walls etc. We recommend applying on surfaces that are pre-primed with Montana GOLD Shock WHITE 9100 to achieve the most intense glow effect. Please consider longer drying time may be required subject to the substrate applied on. Limited resistance to weathering, light and UV-influences. Once completely dry and cured, the longevity and durability of NIGHTGLOW EFFECT spray can be increased by applying Montana VARNISH GLOSS 400ml. We recommend use with Montana Fat Caps (e.g. black / orange).
