PP primer resin can enhance the adhesion of PP materials and plastic parts?

PP water transfer technology is a common surface solution, widely used in small toys, art, packaging products and fitness equipment and other materials surface decoration design and processing technology. However, there is no adhesion phenomenon after the water transfer of PP plastic parts is relatively common. The following small editor of Changzhou Sisai will give you a brief talk, analyze and summarize the reasons for the poor adhesion of PP material water transfer printing and the way to deal with the adhesion problem according to the primer treatment agent.

Puzzle Phenomenon:
PP material plastic parts surface to carry out water transfer to solve, the wall surface or material and one-component primer adhesion is poor, the application of adhesive tape to carry out 100-grid adhesion test, primer paint off and according to the finger pick edge problem.

root cause:
the occurrence of PP material difficult to oil is an urgent need to solve the phenomenon in the surface process treatment, the specific root cause is that it belongs to the non-polar wall or material, and belongs to the crystalline structure, the surface energy is low, resulting in poor adhesion characteristics. Therefore, whether in spraying or water transfer, viscose and other processing technology are very easy to appear the phenomenon of coating is not strong.

solution:

to deal with the difficult problem that the water transfer primer of PP material is not strong, the primer PP surface treatment agent can improve the adhesion between the primer and PP plate according to the actual relay effect of the inner layer between the material and the paint, and after the water transfer is carried out, it is impossible to cause the overall coating to fall off due to the weak adhesion of the primer. The working principle of its application is that on the one hand, it moistens the PP plastic plate and improves its surface positive and negative electrodes, while at the same time, the polymer compound in the treatment agent and the paint epoxy resin produce the actual effect of chemical bond.
