Abstract

The invention discloses a composite coating with adjustable tightness, relates to the field of coatings. The composite coating with the adjustable tightness is prepared by compounding a transfer coating SZ-11 to a composite acrylic coating FL-7104B. The inventors have found that the transfer coating SZ-11 is loosely combined to a PET film, coating adaptability is good, the stripping effect is perfect, the leveling property is good, the brightness is high, and the composite coating does not stick back after molding. The composite acrylic coating FL-7104B is tightly combined to the PET film, sothat the coating performance is good. After the two coatings are mixed, the compatibility, uniformity and stability of the two coatings are good, and a purpose of adjusting the tightness can be achieved by properly adjusting the ratio between the two coatings. The invention discloses a coating process of the composite coating with the adjustable tightness. The coating process is simple and convenient to operate, the requirement on equipment is not high, the composite coating can coat a PET base film well, and the required stripping performance is achieved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a composite coating with adjustable tightness and a coating process thereof. Background technique [0002] At present, in order to prevent their products from being counterfeited, various commodity manufacturers use laser anti-counterfeiting marks to increase the anti-counterfeiting performance of their products. The existing laser anti-counterfeiting marks mainly use PET base film, which is coated with a coating layer on the PET base film, and then aluminum-plated. , narrow-width molding, gluing and other processes, and then introduce an aluminum layer and an adhesive layer on top of the paint layer. [0003] The choice of coating layer directly affects the stripping performance of laser anti-counterfeiting marks. The disposable anti-counterfeiting labels in the prior art are either too tight to peel off and cannot be peeled off, or are too loose to meet the customer's requirements for ...
