Applications:
YMCA terpolymer resin can be applied in the inks, coatings and adhesive possessing high solid content, the specific items are included as below:
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, electronic-chemical aluminum coating, EVA treatment agent, UV primer etc.
heat-transfer printing gum, PTP aluminum foil glue(VC glue), glue for covering steel sheet with film, PVC glue, shoe material glue
transfer printing ink
Solubility:
For YMCA type of terpolymer resin, ketone solvents are especially suited, such as ace-tone, MEK, nadone and isophorone.
Compared with ketone solvents, ester solvents have lower solubility for vinyl resins, such as methyl acetate, ethyl acetate and butyl acetate, but they have good solubility for YMCA resin. Therefore, 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.
Compatibility:
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.
Stability:
YMCA resin has excellent light and heat stability, but when it is used outdoors or at higher temperature, the following stabilizers are suggested to use with it, such as organotin stabilizer without sulphur, epoxy compound stabilizers and light resistant ultraviolet stabilizer.
Packaging:
YMCA resin is usually packaged into the craft paper-plastic composite bag lined with plastic film according to 25Kgs per bag.
Storage:
YMCA resin should be stored in dry place away from sunlight.
Should YMCA resin have been kept over the shelf time, it shouldn’t mean the resin is invalid, but the user has to test the relevant properties of YMCA resin and its finished product before using it in bulk.
Advantage:
More suitable price under the same quality as the one out of China.
Rapid and effective service based on quality and technic.
Shorter lead time based on requirements from clients
