DY-4 is mainly applied in PVC ink, paper ink, electric cable material, pigment paste and flake for PU, PVC adhesive, leather treatment agent, thermal insulating foaming material, additive for PVC modification, calcium-plastic floor, coating etc.
For DY-4 type of bipolymer, ketone solvents are especially suited, such as acetone, MEK, nadone and isophorone. Ester solvents have lower solubility for DY-4 resin, such as methyl acetate, ethyl acetate and butyl acetate etc., Therefore, we need to add a little ketone solvent into the solution while DY-4 resin is dissolved in ester solvents. Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve DY-4 type of bipolymer, but these kinds of solvent are toxic, they are only used in special situation.
DY-4 type of bipolymer is miscible with other resins during the course of usage, such as other types of vinyl chloride vinyl acetate copolymer, PVC resin, perchloro-ethylene resin, ketone resins, chloroprene rubber, NBR, polyacrylate, epoxy resin, polyester and petroleum resin etc.
D) Packaging and Storage
Packaged according to 25Kgs per bag, craft paper-plastic composite bag lined with plastic film.
Should be stored in dry place away from sunlight
Should the DY-4 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 before using it in bulk.
