DY-8 is mainly applied in PVC ink, paper ink, electric cable material, pigment paste and flake for PU, additive for PVC modification, leather treatment agent, thermal insulating foaming material, additive for PVC modification, calcium-plastic floor, coating etc.
For DY-8 bipolymer resin, ketone solvents are specially suited, such as ace-tone, MEK, nadone and isophorone. Ester solvents have lower solubility for DY-8 resin, so we need to add ketone solvents into the solution while DY-8 resin is dissolved in ester solvents.
DY-8 bipolymer resin 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
Usually packaged according to 25Kgs/bag, craft paper-plastic composite bag lined with plastic film;
Stored in dry place away from sunlight;
Should the DY-8 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.
