Adhesion Agent

Adhesion agent in screen printing, mainly used to ensure that the printed pattern or text can be firmly attached to the substrate, to increase the wear resistance, water resistance, chemical resistance and other properties of the printed materials. Its selection has a decisive impact on the quality and durability of the print. It usually consists of resin, solvent, additives, etc., of which the resin is the main component and determines the basic performance. The solvent is used to adjust the viscosity and drying speed, while the additives play the role of enhancement and stabilization.

Usage process:

1、According to the material of the substrate and printing requirements, choose the appropriate product. Ensure the working environment is clean to avoid the influence of dust and impurities on the printed matter.

2、Mix the Adhesion agent, solvent and additives according to a certain proportion and stir well until the ideal printing viscosity is reached.

3、Print the blended ones onto the substrate through the screen plate to ensure that the printed pattern or text is clear and full.

4、After printing, place the printed matter in a ventilated place to dry naturally, or use drying equipment to accelerate the drying process. Drying temperature and time should be adjusted according to the type of adhesive and printing requirements.

5、After drying, the prints are checked for quality and, if necessary, can be cut, laminated and other subsequent processing.

FAQ:

Q1：Why does the print come off?

A1: The peeling phenomenon may be caused by improper selection of Adhesion agent, improper printing process or improper surface treatment of the substrate. You should choose the right product, make sure the printing process is correct, and treat the surface of the substrate appropriately.

Q2: How to avoid cracking phenomenon on printed materials?

A2: Cracking phenomenon is usually caused by the adhesive drying too fast or the print being squeezed by external force. Cracking can be avoided by adjusting its drying speed and printing process. Meanwhile, avoid exerting too much pressure on the print during the printing process.

Q3：What is the reason that the color of the print becomes light after drying?

A3：The light color after drying may be caused by the solvent evaporating too fast in the Adhesion agent. When mixing, the proportion of solvent should be properly controlled to ensure that the color of the printed matter remains stable during the drying process.
