Mix the acrylic acid-2-ethyl hexyl ester, the 2- hydroxyethyl acrylate, the acrylic acid, the vinyl acetate and so on, forming a kind of solvent type acrylic ester adhesive. With the later modification of the adhesive, the protective film pressure sensitive adhesive tapes, which are applied in the FPC manufacture, are produced. Discuss the influences of the type and amount of the plasticizer and the cross-linking agent on the adhesive, and inspect the relationship between the glue thickness and the adhesive¡¯s performances. The results show that the adhesive tape, with the plasticizer TOTM 3%, the cross-linking agent of the mix of the epoxy and the isocyanate 1.5%/1.5% and the glue thickness 8-10 um, has an excellent initial stage performance. With steady thermostability and good acid and alkali resisting performances, the adhesiv tape pass the workshop's pilot plant test and is fully appropriate for the FPC industrial.

A solvent acrylate adhesive is made from a mixture of acrylic-2-ethyl acetate, acrylic-has 2, hydroxyl ethyl ester, acrylic, vinyl acetate. Through late modification of the adhesive, it is can be made into pressure-sensitive adhesive tapes, which is used in the protection of FPC processing. This paper discussed the type of plasticizer and diplomatic coupling agent, and their ratio¡¯s influence on the performance of the adhesive, revealing the relationship between the glue thickness and tape¡¯s performance. The results showed that the tape had outstanding performance with the following conditions: the ratio of partial benzene plasticizer three acid esters, 3%;  the quantity of epoxy department / isocyanate cross linking agent, % 15 / % 1.5;  glue thickness, 8-10 um. The tape had high stability performance with high temperature resistant, acid and alkali resistant. This tape went through the workshop¡¯s testing, and could meet the requirement of the standards of a protective tape, proving its suitability for FPC industry processing.
