Mould assembly acrylic coating FL-7104B compounds to obtain.Inventors have found that transfevent coating SZ-11 is more loose in conjunction with PET film, coating
Adaptability is good, and peeling effect is ideal, good leveling property, and brightness is high, not viscous back after molding.And compound acrylic coating FL-
7104B is tighter in conjunction with PET film, and coating performance is preferable.After above two coating is mixed, the two compatibility, uniformity are preferable,
Stability is preferable, and by the ratio of appropriate adjustment between the two, can achieve the purpose of adjustment elasticity.
The embodiment of the invention also provides a kind of coating process of the adjustable composite coating of elasticity comprising will be above-mentioned multiple
It closes coating and is coated on the surface of PET basement membrane, and dried.The coating process it is simple to operate, it is not high to equipment requirement,
Above-mentioned composite coating can be preferably coated with on PET basement membrane, reach required stripping performance.
Specific embodiment
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, according to normal conditions or manufacturer builds
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
A kind of adjustable composite coating of elasticity and its coating process of the embodiment of the present invention are specifically described below.
The embodiment of the invention provides a kind of adjustable composite coatings of elasticity, by transfevent coating SZ-11 and again
Mould assembly acrylic coating FL-7104B compounds to obtain.
Wherein, transfevent coating SZ-11 is the coating produced by Shanghai Wei Kai photoelectricity technology corporation, Ltd., the original trade mark
For BH-1001C.The solid content of transfevent coating SZ-11 be 17wt%~19wt%, use apply -4 glasss of viscosity measured for
17~21s.The transfevent coating SZ-11 is more loose for disposable coating on a pet film, and the combination of PET film, has coating
Adaptability is good, peeling effect is ideal, levelling is good, brightness is high, molding after non-sticky back the advantages that.
Compound acrylic coating FL-7104B is equally the coating produced by Shanghai Wei Kai photoelectricity technology corporation, Ltd., former
The beginning trade mark is FL-7104B.The solid content of the compound acrylic coating FL-7104B is 14wt%~16wt%, is used
Applying -4 glasss of viscosity measured is 25~35s.The compound acrylic coating FL-7104B is mainly used on PET corona film once
Property coating, and the combination of PET film is tighter, has that good coating wide adaptability, compound fastness, good leveling property, brightness be high, printing
The advantages that wide adaptability.
Inventor creatively has found, above two coating is used in mixed way, and not only the mixed effect of the two is preferable, compatible
Property, uniformity are preferable, can be stabilized after mixing.And by adjusting ratio between the two, it is elastic to can achieve adjustment
The purpose of degree can satisfy client to the different demands of anti-counterfeiting mark stripping performance.
