As I wish to transfer print onto an un-coated hard surface I know I have to treat it with a product like Digi-coat.
I managed to find a chemical breakdown of Digi.. and it seems to consist mainly of Solvents with lots of Xylene.. (not nice).
As you seem to have to 'bake' the product for some time after spraying it appears to be just opening the pores of the material rather than applying a coating.
As Polyester seems to be the favoured material for Sub. inks I had assumed that it may be spraying a coat of this onto the product.
I guess not.
I appreciate that many of you will buy your wares already coated ready for the heat press.. but I wondered if there are any 'chemists' out there who have experimented with any other treatments..
Most Fibreglass resins are Polyester and with it's MEKP catalyst should make a very durable potential surface.. but have yet to try..
Perhaps even a Shellac base..
Your thoughts plis..
