DROH resin is extensively applied in many fields, such as inks,
coatings and adhesive, the details are as below:
Coatings and paints: marine overprinting varnish, common metal
overprinting varnish, corrosion resistant coating for vessel and
marine, shell lacquer for machinery, industrial maintenance paint,
plastic lacquer, can coating, leather coating, high grade PU wood
paint, metal paint etc.
Adhesive: interlamination adhesive, magnetic tape adhesive;
Inks: gravure printing ink for lamination.
DROH 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.
DROH 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,
DROH 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 DROH resin, ketone solvents are specially suited, such as
acetone, MEK, nadone and isophorone. Compared with ketone solvents,
ester solvents have lower solubility for DROH 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
DROH resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as
dichloroethane and diethylene oxide, also can dissolve DROH resin,
but these kinds of solvent are toxic, they are only used in special
For DROH resin, lower molecular weight is helpful for increasing
the solubility of resin and solid content of solution.
DROH type of terpolymer 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.
Packaging and Storage:
DROH resin is usually packaged into the craft paper-plastic
composite bag lined with plastic film according to 25Kgs per bag.
DROH resin should be stored in dry place away from sunlight.
Should DROH 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 DROH resin and its finished product before using it
