Applications:
The application scope of DAGD resin mainly reflects in the following fields:
A. Coatings: 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, high grade PU wood paint, metal paint etc;
B. Adhesive: interlamination adhesive, magnetic tape adhesive;
C. Inks: gravure printing ink for recombination.
Property:
A. DAGD resin is the excellent carrier of pigment used in the inks and coatings because the resin contains VC and VAC;
B. 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.
C. 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.
D. DAGD resin can implement cross linking reaction with thermosetting resins (e.g. Isocyanate) because of hydroxyl functional group in the structure of resin, the formed film has the following excellences, such as bright, hard and tough, wear resistant, scratch resistant, water resistant and chemical resistant etc.
Solubility:
A. Ketone solvents are especially suitable for DAGD resin, such as ace-tone, MEK, nadone and isophorone.
B. Compared with ketone solvents, ester solvents have lower solubility for DAGD resin, such as methyl acetate, ethyl acetate and butyl acetate etc., so we need to heat the solution or add a little ketone solvent into the solution while DAGD resin is dissolved in ester solvents.
C. 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.
D. For DAGD resin, lower molecular weight is helpful for increasing the solubility of resin and solid content of solution.
Compatibility:
DAGD terpolymer resin is easily mixed 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:
Usually packaged in craft paper-plastic composite bag lined with plastic film as per 25Kgs/bag.
Storage:
Stored in dry place away from sunlight.
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.
