1. Acrylic display rack belongs to high polymer plastic, and the surface molecular polarity is very poor. It needs to be treated to increase the polarity, which is conducive to ink adhesion. The usual practice is to treat the product surface, scrub the surface with w-8601 solvent, and then screen printing or pad printing. If conditions permit, plasma treatment is adopted, but the process is relatively complex and the cost is high, so ordinary products are not recommended.

2. The adhesion strength of screen printing on the surface of plexiglass products is mainly related to the ink used. If conditions permit, original imported ink can be used as much as possible, and about 5% curing agent can be added to the ink, so that the adhesion is better.

3. If the adhesion of screen printing is good, it is best to use high-temperature ink and bake at high temperature after printing, which is both environmentally friendly and beautiful. You can also choose enhanced hardening mirror screen printing pad printing ink, baking free and self drying. It is especially suitable for hardening PC, PMMA, UV, UV paint surface and other silk products.

4. The cleaning treatment of the surface of acrylic display rack also has a great impact on the adhesion of screen printing or pad printing. Therefore, before screen printing, it is best to scrub the surface with white electric oil to remove the oil stains on the surface, otherwise various oil stains on the surface will have a negative impact on the adhesion of the ink.
