1. Raw materials of printing materials:

The raw materials of some substrates are difficult or impossible to apply to the thermal transfer process. For example, stainless steel materials without spray paint, wood without topcoat, substrates with two-component paint sprayed on the surface, silicone materials, materials that cannot be heated or pressed, blow molded low-pressure materials, etc.

2. Shape of substrate:

The raw materials of some substrates are difficult or impossible to apply to the thermal transfer process. For example, the surface of the substrate is uneven, the volume of the substrate is too large or too small, the printing area of the substrate is too large or too small, etc.
3. There are also some substrates that cannot be distinguished accurately from a theoretical point of view, and must be distinguished through thermal transfer and trial hot stamping.

What should I do if the silicone thermal transfer treatment agent cracks?

During the operation of silicone heat transfer printing, people often encounter some problems. The most common phenomenon is that the silicone heat transfer treatment agent silica gel cracks, which is even more troublesome. Faced with such a situation, how should we deal with it? Well, first we need to clean the oil and dust on the surface of the silicone to keep it clean;

​

The second step is to evenly apply the silicone thermal transfer treatment agent on the two silicone interfaces to be bonded, leave it for 5 minutes, and then proceed to the next process. Finally, we evenly apply glue on one side of the silicone and fit the two together. This solves this phenomenon and makes our products better.
In addition to solving the problem of cracking of silicone treatment agent, we also need to pay attention to certain methods in the manufacturing process. How to use silicone treatment agent correctly is a very important issue. It will directly affect product quality, so we also How to use this silicone treatment agent correctly? First, wipe off the dirt on the sticky surface of the silicone rubber substrate with toluene. After keeping it clean, apply the treatment agent on the substrate by brushing or spraying it, and it needs to be evenly distributed. Also, put the coated film on a rack to dry in a dry environment at room temperature for 5-10 minutes. We must be careful not to have dust, as this will cause adverse effects on the appearance of the product.
