Sublimation coating is a crucial step in the process of sublimation printing on mugs. It is a special coating that allows the ink to adhere to the surface of the mug and create a long-lasting, vibrant image. If you’re interested in sublimation printing and want to know how to make sublimation coating for mugs, then you’re in the right place! Mecolour, as a Chinese factory with more than ten years of rich experience in the production of sublimation coating mugs, will discuss everything you need to know about making mugs with sublimation coating.
What is Sublimation Coating?
Sublimation coating is a thin layer of material that is applied to the surface of the mug before the sublimation printing process. The coating is made up of a special blend of chemicals that create a surface that is receptive to sublimation ink. Without the coating, the ink will not adhere to the surface of the mug, and the printing will not be successful.
Ingredients for Making Sublimation Coating
To make sublimation coating for mugs, you’ll need the following ingredients:
1.Polyurethane (PU) Resin: Polyurethane resin is a synthetic material that is commonly used in coatings, adhesives, and paints. It is a versatile material that can be used in a wide range of applications, including sublimation coating.
2.Water: Water is used as a solvent to dissolve the polyurethane resin.
3.Isopropyl Alcohol: Isopropyl alcohol is used as a surfactant to help the polyurethane resin spread evenly on the surface of the mug.
4.Silicone Oil: Silicone oil is used as a levelling agent to ensure that the sublimation coating is smooth and even.
5.Sublimation Coating Additive: This additive is a blend of chemicals that are specifically designed to enhance the properties of the sublimation coating. It improves the adhesion of the ink to the surface of the mug and enhances the vibrancy of the printed image.

How to Make Sublimation Coating for Mugs?
Now that you have all the ingredients, it’s time to make the sublimation coating for mugs. Here’s how:
Step 1: Mix the Polyurethane Resin and Water
In a clean container, mix the polyurethane resin and water in a 1:1 ratio. Use a stirring rod to ensure that the mixture is well combined.
Step 2: Add Isopropyl Alcohol
Add a small amount of isopropyl alcohol to the mixture and stir well. The isopropyl alcohol acts as a surfactant, which helps the polyurethane resin spread evenly on the surface of the mug.
Step 3: Add Silicone Oil
Add a few drops of silicone oil to the mixture and stir well. The silicone oil acts as a levelling agent, which ensures that the sublimation coating is smooth and even.
Step 4: Add Sublimation Coating Additive
Add the sublimation coating additive to the mixture and stir well. The additive enhances the properties of the sublimation coating, improving the adhesion of the ink to the surface of the mug and enhancing the vibrancy of the printed image.
Step 5: Apply the Sublimation Coating
Using a spray gun, apply the sublimation coating to the surface of the mug. Apply a thin, even layer, making sure to cover the entire surface of the mug. Allow the coating to dry completely before proceeding with the sublimation printing process.
