Because the resin contains VC and VAC, DAGD resin is the excellent
carrier of pigment used in the inks and coatings. Moreover, it
possesses excellent adhesion on the following items, such as PET,
resin primers, paper, acrylic resin, PVC, ABS, PC, the surface of
ink, pretreated PE and OPP etc.
DAGD resin is often used with other film-forming materials to
improve the properties of coating and strengthen adhesion,
flexibility, toughness, hardness and chemical resistance. Because
of hydroxyl functional group in the structure of resin, DAGD resin
can implement cross linking reaction with thermosetting resins
(e.g. Isocyanate), the formed film has the following excellences,
such as bright, hard and tough, wear resistant, scratch resistant,
water resistant and chemical resistant etc.
Solubility & Compatibility:
Ketone solvents are especially suited for DAGD resin, such as
acetone, MEK, nadone and isophorone.
Compared with ketone solvents, ester solvents have lower solubility
for DAGD 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 DAGD resin is dissolved in ester
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as
dichloroethane and diethylene oxide, also can dissolve DAGD type of
terpolymer resin, but these kinds of solvent are toxic, they are
only used in special situation.
Lower molecular weight is helpful for increasing the solubility of
resin and solid content of solution for DAGD resin.
DAGD copolymer 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.
Packaging and Storage:
DAGD resin is usually packaged into the craft paper-plastic
composite bag lined with plastic film according to 25Kgs per bag.
DAGD resin should be stored in dry place away from sunlight.
Any queries on technology or quality assurance can be inquired to
Should DAGD 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 DAGD resin and its finished product before using it
