Applications:
DAGD resin is extensively 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.
Property:
DAGD resin is the excellent carrier of pigment used in the inks and
coatings because the resin contains VC and VAC, meanwhile, 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:
For DAGD resin, ketone solvents are specially suited, such as
ace-tone, 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
solvents.
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.
For DAGD resin, lower molecular weight is helpful for increasing
the solubility of resin and solid content of solution.
DAGD terpolymer 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 our
company. 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 in bulk.
Competitive Advantage:
More appropriate price under the same quality as the one out of
China.
Timely and effective service based on quality and technic.
Shorter lead time based on requirements from clients.
