Applied in marine overprinting varnish, common metal overprinting
varnish, corrosion resistant coating for vessel and marine, lacquer
for machinery shell, industrial maintenance paint, plastic lacquer,
can coating, leather coating, interlamination adhesive, magnetic
tape adhesive, gravure printing ink for recombination, high grade
PU wood paint, metal paint etc.
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.
The excellent carrier of pigment used in the inks and coatings,
excellent adhesion, used with other film-forming materials to
improve the properties of coating, and strengthen adhesion,
flexibility, toughness, hardness, chemical resistance etc.
DAGH type of 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
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.
More appropriate price under the same quality as the one out of
Timely and effective service based on quality and technic.
Shorter lead time based on requirements from clients.
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
