DAGH resin is extensively applied in 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, interlamination adhesive, magnetic tape adhesive, gravure printing ink for recombination, high grade PU wood paint, metal paint etc.
C) 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. Because of hydroxyl functional group in the structure of resin, DAGH type of 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.
D) Packaging and Storage
Packaged according to 25Kgs/ag, craft paper-plastic composite bag lined with plastic film.
Stored in cool and dry place away from sunlight.
Should the DAGH has been kept over the shelf time, it shouldn’t mean the resin is invalid, but the user has to test the relevant properties before using it in bulk.
