Applications:
Principally used for:
PVC ink, silk-screen printing ink, paper ink,
leather treatment agent, transfer printing coating,
CPVC and PVC adhesive,
electric cable material, pigment paste and flake for PU, thermal
insulating foaming material, additive for PVC modification,coating
etc.
Solubility&Compatibility:
For DY-3 resin, ketone solvents are specially suited, such as
acetone, MEK, nadone and isophorone.
Ester solvents have lower solubility for DY-3 resin, such as methyl
acetate, ethyl acetate and butyl acetate etc., so we need to heat
the solution or add ketone solvents into the solution while DY-3
resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as
dichloroethane and diethylene oxide, also can dissolve DY-3 type of
bipolymer, but these kinds of solvent are toxic, they are only used
in special situation.
DY-3 polymer resin is miscible with other resins during the course
of using, 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.
Packaging and Storage:
A. Packaged into the craft paper-plastic composite bag lined with
plastic film
B. 25Kgs per bag.
C. Stored in dry place away from sunlight.
Others:
A. Any queries on technology or quality assurance can be inquired
to our company.
B. Should DY-3 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-3 resin and its finished product before
using it in bulk.
