SIIC Liquid filter bags used in Solvent Based Coatings for Printing Plates

As filtration specialist, SIIC team from Shanghai Filterworkshop Co., Ltd(Shanghai Indro Industry Co., Ltd) is very glad to share with about “Liquid filter bags used in Solvent Based Coatings for Printing Plates” as followings:

The process of Solvent Based Coatings for Printing Plates is as followings:

Solvent Totes---Solvent filtration---holding tank---solvent dispenser

In the process of solvent filtration, SIIC extended life pp liquid filter bags with 3 micron are recommended. The purpose is Provide Clean Coating On Printing Plate to Eliminate Defects.

Application: Printing Plate Coating

Purpose of Filtration: Provide a clean coating on the printing plate to eliminate defects in printing.

Application: The coating solutions that will be applied to the aluminum sheet contain photosensitive solids. During the process of coating the aluminum roll sheet, the solvent is evaporated of all liquid and the solids that remain adhere to the aluminum. Solids that remain must be 5 micron or smaller to that they are not visible to the eye or to touch. Larger particles will cause defects when these plates are used in the printing process.

Two basic types of coatings are used; solvent based and water based. Water based coatings tend to develop more gels requiring the use of a SIIC extended life 3 micron pp liquid filter bag. SIIC extended life 3 micron pp liquid filter bag is used on the solvent based coating.
