K Value 41-45 Vinyl Chloride Polymer Resin DY-7 Equivalent To H15/42TF Used In Inkjet Inks PVC silk-screen printing Ink

Vinyl Chloride-Vinyl Acetate Bipolymer Resin (DY-7)

A) Technologic Index

B) Application

DY-7 resin is mainly applied in strippable coating, inkjet inks, PVC ink, silk-screen printing ink, paper ink, electric cable material, pigment paste and flake for PU, PVC adhesive, inks and coatings possessing high gloss and high solid content etc.

C) Solubility & Compatibility

For DY-7 type of bipolymer, ketone solvents are especially suited, such as ace-tone, MEK, nadone and isophorone. Ester solvents have lower solubility for DY-7 resin, such as methyl acetate, ethyl acetate and butyl acetate etc. Therefore, we need to heat the solution or add ketone solvents into the solution while DY-7 resin is dissolved in ester solvents. Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve DY-7 type of bipolymer, but these kinds of solvent are toxic, they are only used in special situation.

DY-7 type of bipolymer is miscible with other resins during the course of usage, such as other types of vinyl chloride vinyl acetate copolymer, PVC resins, perchloro-ethylene resin, ketone resins, chloroprene rubber, NBR, polyacrylate, epoxy resin, polyester and petroleum resin etc.

D) Packaging and Storage

DY-7 resin is usually packaged according to 25Kgs per bag, which is the craft paper-plastic composite bag lined with plastic film.

DY-7 resin should be stored in dry place away from sunlight.

Any queries on technology or quality assurance can be inquired to our company. Should DY-7 resin have been kept over the shelf time, it shouldn’t mean the resin is invalid, but the user has to test the relevant properties of DY-7 resin and its finished product before using it in bulk.
