Luminescent pigment S-ZZ300

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.

Thanks to its fine particle size 20-30um luminescent pigment S-ZZ300 will be perfect for making glow in the dark paint (very good coverage and smooth surface) or in any other application where sedimentation can be a problem. However small particle size also means inferior glowing power to bigger particle pigments like L-ZZ660 (but still its glowing is good compared to some other colours like pink or yellow). On third photo you can see pigments S-ZZ300 and L-ZZ660 - because of strong glowing of L-ZZ660 pigment glowing of S-ZZ300 looks worse than it is in reality. Due to its fine particle size and the fact that it has daytime colour nearest to white among yellow-green glowing pigments it will be perfect choice for making glow in the dark paint for watches.

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.
