Luminescent pigment XL-ZZ1150

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 XL-ZZ1150 has both very big particle size 220-280um and the strongest glowing properties in our offer. In fact it has over two times better glowing than already good glowing pigment L-ZZ500. It is also worth to mention that in long time distances this pigment has outstanding level of glowing. For example after 1 hour in darkness glowing of pigment L-ZZ500 is 60mcd/m2, for pigment L-ZZ660 this value is 100mcd/m2, while pigment XL-ZZ1150 has glowing 168 mcd/m2. But relatively big particle size of this pigment makes it hard to use in most of applications. In case of painting it will leave badly covered and rough surface. On the other hand it will works well in case of mixing with epoxy resin in deeper layers. Adding 10-20% of smaller particle pigment like L-ZZ660 or even S-ZZ300 will result in more even glowing and coverage.

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.
