Applications:
DROH resin can be used for a wide range of coatings applications for maintenance, marine and metal finishes,marine anti-corrosion paint, cans paint, wood and plastic finishes, paper and leather coatings, PET inks, adhesive for magnetic tape and carbon ribbon etc.
Property:
DROH 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.
DROH 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, DROH 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 DROH resin, ketone solvents are specially suited, such as ace-tone, MEK, nadone and isophorone. Compared with ketone solvents, ester solvents have lower solubility for DROH resin, such as methyl acetate, ethyl acetate and butyl acetate etc.
DROH type of terpolymer is miscible with other resins during the course of usage, such as other types of vinyl chloride vinyl acetate copolymer, PVC resins, perchloro-ethylene resin, ketone resins, chloroprene rubber, NBR, polyacrylate, epoxy resin, polyester and petroleum resin etc.
Packaging and Storage:
DROH resin is usually packaged into the craft paper-plastic composite bag lined with plastic film according to 25Kgs per bag.
DROH resin should be stored in dry place away from sunlight.
Must be in clean vehicle with awning and keep away from moisture while transporting.
It is NOT hazardous article, and the shelf life is six months from the delivery date.
Should DROH resin have been kept over the shelf time, it doesn’t mean the resin is invalid, but the user has to test the relevant properties of DROH resin and its finished product before using it in bulk.
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.
