Luminescent pigment M-ZZ620

If you are not sure which pigment you should choose for your application we encourage you to read a short manual "How to choose proper luminescent pigment". Also a lot of important informations can be found in FAQ. Both you can find on the bottom of our website.

Luminescent pigment aka glow in the dark powder is produced basing on strontium aluminate. This is new generation of this kind of pigments superior to older generation baed on sulphides. It isn't flammable, toxic nor radioactive. Also it's neutral to environment. However, strontium aluminate creates small, hard and rough crystals which may cause irrytation, because of this fact during work with raw luminescent pigment you should protect your eyes and airways. Glow in the dark powder absorbs both visible light and UV, unlike the older generation UV doesn't destroy it.

This pigment isn't waterproof, hence we should use it only with solvent based medium that not contain water and will well protect pigment particles against moisture. It's also important to use medium which isn't strong acid or alkali – in such environment pigment may be destroyed.

Luminescent pigment M-ZZ620 has strong glowing power (similiar to L-ZZ660 pigment) and fine particle size 45-65um. If due to technological limits it's impossible to use big particle sized L-ZZ660 pigment (0,1mm) or we simply want good surface coverage then pigment M-ZZ620 will be ideal for us. Only disadvantage of this pigment is its price. Surely this pigment will be a good option for painting or making small details from resin or rubber (like jewerly or glow in the dark fishing baits) where bigger particle size can be problematic. Alternative is glow in the dark pigment S-ZZ300 (which has even smaller particle), but its glowing power is about two times worse.

On this photo you can see pigments M-ZZ620 and L-ZZ660.

Basic rules of using luminescent pigments:

• Depending of used medium and anticipated result producer suggest to use 5% up to 30% of pigment by mass. It is mostly recommended to make some tests before starting main work with pigment – thanks to it we will determine the best proportions of mixing for our application.

• Medium that we will use with luminescent pigment should be transparent as much as possible. Thanks to it pigment will get enough light to charge and its glowing will be not interrupted. It's possible (and sometimes even suggested) to mix some dye with medium to get interesting colour of product in daylight – but please remember to add only a bit of dye to keep medium transparent. Less transparent medium will cause weaker glowing – but very small addition of dye not harm glowing much.

  If we use thin layer of pigment (for example we use it as a paint) it's important to put it on bright surface – dark colour of surface can effectively decrfease gllowing power of pigment.

  In case of painting it may be also a good idea to make 2-3 layers instead of one thick.

• This pigment isn't waterproof. Due to this fact we should store it in dry place, properly sealed. During work with pigment we should avoid using medium contaminated with water.
