Yellow-green pigment ZZ660 made from strontium aluminate. This is better glowing version of ZZ500 pigment. Way more efficient than old generation zinc sulphide based pigments. It's non toxic nor radioactive but not recomended to have contact with human body (may irritate skin and eyes). Pigment is not waterproof and in case of contact with water or acids it degradate to safe for human and environment products. It can be mixed with any transparent, non-water medium like synthetic resin, silicone, glue, plastics, paint, wax... In case of painting black or dark surfaces it's suggested to paint it white at first. Without it glowing effect will be more or less decreased.
