Question:

I'm searching for the coating material along with the curing and spraying equipment for polyester coatings. We want to coat tiles for the dye sublimation process. I have searched the supplier pages, but wasn't able to find a supplier. Thanks for your assistance. B. J.

Answer:

I am surprised to hear you can't find polyester coatings. They have been commercially available for many years. You can find polyester casting and coating resins at craft stores in quart and gallon packages. For larger amounts they are available from some of the larger paint manufacturer and in some cases at their factory stores. They may also be available at automotive supply stores. You will want to use the two-component polyester coatings because they are self-curing. They do not have to be baked, and you will not need an oven or other curing equipment.

Polyester coatings can be applied using conventional and two-component spraying equipment. Using conventional equipment, you must be mindful of the coating's pot life so that it does not set-up in the spray gun. On the other hand, two-component spraying equipment keeps the components separate until they are mixed at the spray gun. You can handle much faster curing formulations using two-component equipment.
