Do you have to put epoxy on sublimation tumblers?
Applying epoxy to sublimation tumblers is not a strict requirement, but it is a common practice for several reasons:
-
Protection: Epoxy resin provides a protective layer over the sublimated design. This can help prevent scratches, fading, and damage to the print, ensuring the longevity of the design on the tumbler.
-
Smooth Finish: Epoxy can give the tumbler a smooth and glossy finish, enhancing the overall appearance of the product. It provides a polished look that many customers find attractive.
-
Waterproofing: Epoxy coating can make the tumbler more resistant to water, making it suitable for use in various conditions. This can be particularly beneficial for tumblers that are likely to be exposed to moisture or used outdoors.
-
Durability: The epoxy layer adds an extra level of durability, making the tumbler more resistant to wear and tear. It helps protect the sublimated print from daily use and handling.
While epoxy coating has these advantages, it's essential to follow proper application techniques to avoid issues such as bubbles or uneven surfaces. Additionally, some people may prefer the natural feel of the sublimated print without an epoxy coating.
Ultimately, whether to use epoxy on sublimation tumblers depends on personal preference and the specific requirements of the intended use. Some sublimation tumblers come pre-coated with a polymer layer that serves a similar protective purpose, and in such cases, additional epoxy coating may not be necessary.
