MANUFACTURING METHOD OF DOUBLE PRESSURE SENSITIVE ADHESIVE WITHOUT SUBSTRATE USING DUAL CURE METHOD

摘要

PURPOSE: A manufacturing method of a non-carrier double-sided pressure-sensitive adhesive tape is provided to improve internal crosslinking density of adhesive composition, to be able to quickly hardened, to have excellent surface roughness, and to obtain a high transparency adhesive tape without distortion of object, by continuously conducting thermal curing and UV curing. CONSTITUTION: A manufacturing method of a non-carrier double-sided pressure-sensitive adhesive tape comprises: a step of forming an adhesive layer(200) by coating liquid type adhesive composition on one side by transferring a first release film(100); a step of first curing the adhesive layer by applying heat while transferring a first release film(300) in which the adhesive layer is formed; a step of second curing the adhesive layer by irradiating UV while transferring the first release film; and a step of bonding a second release film on one side of the adhesive layer while transferring the first release film.
