Description
Specifications
  • This Photochromic Pigment set can be used to demonstrate and investigate light reactive Smart Materials
  • The Kit contains:A set of 3 x Photochromic Pigments (Purple, Orange and Magenta)
  • UV Fluid
  • Glow in the Dark PigmentPhotochromic Pigments:These pigments normally have a pale, off‐white appearance but in sunlight or UV light they instantly change to a bright, vivid colour
  • The pigments revert to their pale colour when away from sunlight or UV light
  • Supplied in a plastic syringes containing 3g of pigment
  • UV Fluid:This liquid is non‐toxic liquid paraffin containing a UV sensitive photochromic dye
  • Indoors it appears as a clear liquid but when exposed to natural light it immediately becomes coloured
  • This colour increases in intensity when exposed to direct sunlight
  • The colour change is reversible, although it takes about 60 seconds for the liquid to become clear again
  • Makes a fantastic demonstration of photochromic phenomena
  • The same dye chemistry is used in photochromic lenses, special window glass etc
  • Photochromic cells, for quantitative measurements, can be made, by trapping a drop of the fluid between microscope slides or petri dishes
  • The material can be activated by UV
  • Supplied as a 50ml pot
  • Glow in The Dark Pigment:This pigment absorbs and stores sufficient energy to give an afterglow lasting up to ten times longer than zinc sulphide phosphorescents
  • After exposure to natural or artificial light, it will glow practically all night
  • The pigment can be mixed and applied with white acrylic paint
  • When the acrylic hardens, it effectively locks the pigment into a water–resistant film
  • It should be noted that the pigment is highly concentrated and only very small amounts are needed to produce glow–in–the–dark effects
  • Supplied as a 5g pack in a clear plastic container
