Applications:
DAGD resin 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.
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 acetone, 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.
