Description
This pen was the first to be developed by Ink Intelligent.
It shows a striking colour change from blue to pink when exposed to UV light on a photocatalytic surface. The ink is easily washed away with water.
Most suitable for surfaces of an activity similar to of a typical commercial self-cleaning glass – medium activity for short.
It is not suitable for reactive surfaces which have chemicals present that are able to trigger the colour change. Although not common, this false colour change is usually seen in the dark (i.e. without irradiation) and in such cases none of the photocatalytic indicator inks are likely to be appropriate. If in doubt which ink to choose to test your substrate – please send a sample of the material and we’ll be happy to advise on the most appropriate ink to use.
