DAGH can be used for a wide range of coatings
applications,including marine anti-corrosion paint gravure printing
inks,chassis paints, maintenance, PU and wood finishes, paper
coatings, PET inks, interbedded adhesive, adhesive for magnetic
tape and carbon ribbon.
DAGH is white or slight yellow powder,ketone soluble with
colorless,transparent solution and has excellent adhesion on
PET,resin primer,paper,PVC,ABS pre-treatment of PE and OPP.It is
often used with other film-forming material to improve the coating
performance,and enhance paint
adhesion,flexibility,tenacity,hardness and chemical resistance.The
hydroxyl functional group permits crosslinking reactions for
thermoset,obtaining excellent chemical/water resistance.
Solubility & Compatibility:
For DAGH resin, ketone solvents are specially suited, such as
acetone, MEK, nadone and isophorone. Compared with ketone solvents,
ester solvents have lower solubility for DAGH type of 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 DAGH type of resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as
dichloroethane and diethylene oxide, also can dissolve DAGH type of
terpolymer resin, but these kinds of solvent are toxic, they are
only used in special situation。
For DAGH resin, lower molecular weight is helpful for increasing
the solubility of resin and solid content of solution.
DAGH type of terpolymer 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:
DAGH resin is usually packaged into the craft paper-plastic
composite bag lined with plastic film according to 25Kgs per bag.
DAGH resin should be stored in dry place away from sunlight.
Any queries on technology or quality assurance can be inquired to
Should DAGH 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 DAGH resin and its finished product before using it
