Scratch-off paints for industries
Scratch-off paints are a set of special paints and a varnishes which are meant to cover up the layer containing an information and to be easily removable (revealing).
It is comprised of 2 paints and a varnish. The first paint is used for applying informational, key elements to this product.
Next, a transparent anti-adhesive varnish is applied on the first layer, and then the actual scratch-off paint, characterised by poor adhesion to the substrate and desired scratch properties (coming off in rolls, not chips, appriopriate stability of effect over time, etc.) is applied on it.
The actual scratch-off paint should be applied with an appriopriate layer thickness so that the information underneath stays sufficiently hidden.
