B) Application
YMCA type of terpolymer resin can be applied in the coating and adhesive possessing high solid content, plastic and metal overprinting varnish, metal corrosion resistant coating, maintenance lacquer, repair lacquer, vessel and marine lacquer, rolling material coating, spray paint for plastic shell, interlamination coating, can coating, aluminium foil varnish, heat-transfer printing gum, transfer printing ink, electronic-chemical aluminum coating, PTP aluminum foil glue(VC glue), glue for covering steel sheet with film, PVC glue, shoe material glue, EVA treatment agent, UV primer etc.
Compared with ketone solvents, although ester solvents have lower solubility, we don’t need to heat the solution or add ketone solvents into the solution while YMCA resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve YMCA terpolymer resin, but these kinds of solvent are toxic, they are only used in special situation.
YMCA type of 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.
Packaged in the craft paper-plastic composite bag, lined with plastic film, 25Kgs/ bag.
Stored in dry place away from sunlight.
Should the YMCA resin have been kept over the shelf time, it shouldn’t mean the resin is invalid, but the user has to test before using it.
