What are the requirements for adhesion promoters in the process of painting and gluing?

In the process of surface treatment, the form is mainly concentrated in painting, electroplating and gluing. Different processes have different values or surface effects, but they also face many problems in the actual construction process. Poor surface treatment. Taking spray paint and glue as an example, it is reflected in the unqualified test of spray paint and the poor firmness between adhesive and degumming substrate and glue. The above problems are generally solved by applying primer adhesion treatment agent, so what are the requirements for the adhesion treatment agent in the process of painting and gluing?

adhesion treatment agent is mainly to enhance the adhesion between the paint substrate and the paint film through the primer adhesion treatment agent. The principle is to improve the wettability, enhance the polarity and chemical bond adhesion principle. The adhesive aspect is to strengthen the binding firmness of the glue and the substrate, and the repair area is reflected in the area where the UV paint repair is not good. Below we explain the demand for adhesion treatment agents from three aspects: paint peeling, material adhesive degumming and UV paint defect repair, as follows:

1. Solve the phenomenon of spraying 100 cells on the substrate

understand the spraying material and operation process, confirm whether it is the adhesion between the substrate and the topcoat, or the adhesion between the coating and the topcoat, and provide information and specific solutions for the paint stripping phenomenon during the spraying process.

2. The firmness of reinforcing material adhesive

material viscose technology, viscose to enhance the adhesion of the mature program is PP and nylon materials. If such materials are used, we can continue to understand whether the customer's glue type (hot melt adhesive, waterborne polyurethane, oil-based adhesive) has benzene requirements for treatment agents, and provide samples according to the actual customer's situation.

3. Repair of UV painting

heavy spraying is generally based on UV, and the scope of heavy spraying includes: color difference of products, dust spots, particles and other defects in finished products. Rework water is recommended if you understand the reason for the need for rework and repainting. Use repair water drying effect will be better.

worth noting that the demand for adhesion treatment agents is different from the actual classification and use. The need is to solve phenomena and problems. In fact, due to different materials, the adhesion treatment agent mainly acts on the substrate, so it is necessary to select the adhesion treatment agent according to the substrate, such as nylon adhesion treatment agent, PP adhesion treatment agent, metal adhesion treatment agent, electroplating treatment agent, UV repair water, etc., to effectively distinguish, in order to achieve accurate application.
