Effect of wax powder on the transfer of aluminum profile wood grain

aluminum profile conventional powder coating formulation often add edgy types of low molecular weight, low melting point wax powder to make the coating have a good scratch, anti-block, wear-resistant, light-cancelling, degassing and texture effect, but look at the aluminum profile thermal sublimation transfer powder coating data, found that many people in the formula to add wax powder is skeptical attitude, think that after adding wax powder powder in the heat transfer will produce "sticky paper" phenomenonHowever, in the course of the experiment, we found that wax powder has a positive effect on the de-papering of the aluminum profile heat transfer powder coatinguploads./powder/uploadFile/2014-7/201473020455293098.jpg.
Group A did not add wax powder, Group B added 0.3% of the wax powderAfter the powder spray plate, the hardness of Group B is higher than that of Group A, the AB two sets of paper printing are less after vacuum transfer, and the effect of group B transfer is better than group AGroup C did not add wax powder, Group D added 0.2% of the wax powder, powder spray plate, Group D hardness than Group C higher, vacuum transfer after CD two groups of marks less, D group transfer effect is better than Group CWe found through experiments that the appropriate addition of wax powder can increase the hardness of the coating, improve the coating leveling, help to improve the "sticky paper" and after transfer of the remaining marks on the surface of the coating, but some wax powder added to the surface is not conducive to transfer, some of the wax powder on the coating leveling has a role in promoting, but has a great impact on the transfer effect
