whats the thick protective varnish on vandal proof signs?
Hi everyone.
A customer has asked me to make a number of signs as vandel resistant as possible, he showed me an example of one he had seen. It seems to have a thick layer of extremely hard varnish all over it. The sign is a tray with a full colour print mounted on the toponly. would any one have an idea to what could have been used to create this. Looking side on the varnished layer seems to be 2 – 3 mm thick.Thanks
