Impurity Particle No.
Colorless, Transparent, No insoluble matter
DY-1resin is mainly applied in strippable coating, 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-1 type of bipolymer, ketone solvents are specially suited,
such as acetone, MEK, nadone and isophorone. Ester solvents have
lower solubility for DY-1 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-1 resin
is dissolved in ester solvents. Chlorohydrocarbons, Nitro compound
and alicyclic solvents, such as dichloroethane and diethylene
oxide, also can dissolve DY-1 type of bipolymer, but these kinds of
solvent are toxic, they are only used in special situation.
DY-1 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) Pigments & Stuffing
Most of pigments and stuffing can be used with DY-1 type of
bipolymers, such as titanium dioxide, chromium oxide green, carbon
black, chrome yellow, barite, mica powder, talcum powder, calcium
carbonate etc. We have to be extremely careful when use zinc,
cadmium and ferric oxide as the pigment, because they have
catalysis at high temperature for decomposition reaction of vinyl
chloride vinyl acetate copolymers.
DY-1 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
F) Packaging and Storage
DY-1 resin is usually packaged according to 25Kgs per bag, which is
the PP knitted bag lined with plastic film. Sometimes, craft
paper-plastic composite bag lined with plastic film is also used
according to the customer’s requirements.
DY-1 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-1 resin has been kept over the shelf time, it
doesn’t mean the resin is invalid, but the user has to test the
relevant properties of DY-1 resin and its finished product before
using it in bulk.
