DY-7resin 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.
Solubility & Compatibility:
For DY-7 type of bipolymer, ketone solvents are especially suited,
such as acetone, 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.
DY-7 resin has excellent light and heat stability, but when it is
used outdoors or at higher temperature, the following stabilizers
are suggested to use with it, such as organotin stabilizer without
sulphur, epoxy compound stabilizer, light resistant ultraviolet
Packaging and Storage:
DY-7 resin is usually packaged into the craft paper-plastic
composite bag lined with plastic film according to 25Kgs per bag.
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.
