First, what is the adhesion of resin

Resin adhesion refers to the ability of the resin coating to adhere to the substrate. Insufficient adhesion of the resin on the surface can cause it to fall off or foam, and affect the service life and performance of the product.

Second, how to effectively improve the adhesion of resin

1. Surface treatment

Surface treatment is an effective method to improve the adhesion of resin. By obtaining surface roughness and increasing surface energy, the ability of the resin to adhere to the surface of the substrate can be improved. Surface treatment can be achieved by sandblasting, chemical cleaning and other methods.

2. Temperature control

Temperature is also an important factor affecting the adhesion of resin.  The high temperature will cause the resin to cure quickly and reduce the adhesion between the resin and the substrate.  If the temperature is too low, it will lead to poor resin fluidity and reduce the diffusivity of the resin.  Therefore, during the production process, attention should be paid to controlling the temperature of the resin and the substrate, and the resin coating should be carried out at the correct temperature.

3. Selection of resin adhesive

The choice of resin binder is also an important factor to improve the adhesion of resin. Different adhesives have different effects on different substrates, which should be selected according to the substrate type and the resin coated object. Commonly used adhesives are acrylic resin, epoxy resin and polyurethane resin.

4. Improve the accuracy and uniformity of resin coating

The precision and uniformity of the resin coating are also important. If the thickness of the resin coating is not uniform, it will lead to reduced adhesion, and the uniformity of the coating should be improved by adjusting the coating speed and coating method during the production process.

5. Ensure drying time and curing quality

The drying time and curing quality of the resin coating are also important. If the resin coating is moved or subjected to pressure before curing, the adhesion of the resin will be affected. In the production process, the curing time and curing quality of the resin should be guaranteed to improve the adhesion of the resin
