The scope of use of DAGH mainly reveals the following aspects:
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,
Glue: interlamination adhesive, magnetic tape adhesive, high grade PU wood paint, metal paint etc.
Inks: gravure printing ink for lamination,
DAGH 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.
The excellent carrier of pigment used in the inks and coatings, excellent adhesion, used with other film-forming materials to improve the properties of coating, and strengthen adhesion, flexibility, toughness, hardness, chemical resistance etc.
Ketone solvents are specially suitable for DAGH resin, such as acetone, MEK, nadone and isophorone. Because ester solvents have lower solubility for DAGH type of resin than ketone solvents, such as methyl acetate, ethyl acetate and butyl acetate etc., we have to heat the solution or add ketone solvents into the solution while DAGH type of resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve DAGH type of terpolymer 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.
DAGH 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.
DAGH resin is usually packaged into the craft paper-plastic composite bag lined with plastic film according to 25Kgs per bag.
DAGH resin should be stored in dry place away from sunlight.
If DAGH resin has 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.
