Applications:
Used in a wide range of coatings applications,including marine anti-corrosion paint, gravure printing inks,chassis paints, maintenance paints, PU and wood finishes, paper coatings, PET inks;
interbedded adhesive, adhesive for magnetic tape and carbon ribbon.
Property:
DAGH is white or slight yellow powder,ketone soluble with colorless,transparent solution and has excellent adhesion on PET,resin primer,paper,PVC,ABS pre-treatment of PE and OPP.It is often used with other film-forming material to improve the coating performance,and enhance paint adhesion,flexibility,tenacity,hardness and chemical resistance.The hydroxyl functional group permits crosslinking reactions for thermoset,obtaining excellent chemical/water resistance.
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 need 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.
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.
Packaging and Storage:
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.
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.
