The Explorer Ink (Rz Ink)
Best suited for medium activity surfaces.
Intelligent ink in a bottle with a paintbrush applicator. It is the Explorer (RZ pen) activity ink, slightly tweaked so it suits better more porous, less even photocatalytic surfaces.
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.
