Applications:
DAGH resin is extensively applied in many industries, such as coatings and paints, adhesives and glue, inks, the details are as below:
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.
interlamination adhesive, magnetic tape adhesive;
gravure printing ink for lamination;
Solubility:
For DAGH resin, ketone solvents are specially suited, such as ace-tone, 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 have to heat the solution or add ketone solvents into the solution while DAGH is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve DAGH 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.
Property:
DAGH 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.
DAGH type of resin is often used with other film-forming materials to improve the properties of coating, and strengthen adhesion, flexibility, toughness, hardness, chemical resistance etc.
DAGH 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.
Compatibility:
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.
Advantage:
More competitive price based on the same quality;
Rapid and effective service according to requirements from customers;
Shorter lead time based on requirements from clients.
Any queries on technology or quality assurance can be inquired to our company.
Packaging:
DAGH resin is usually packaged into the craft paper-plastic composite bag lined with plastic film according to 25Kgs per bag.
Storage:
DAGH resin should be stored in dry place away from sunlight.
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 in bulk.
