1. Applications:
YMCH copolymer resin with carboxyl group is currently used in lots of industries:
Coating industry: plastic and metal overprinting varnish, metal corrosion resistant coating, maintenance paint, repair paint, vessel and marine lacquer, rolling material coating, spray paint for plastic shell, interlamination coating, can coating, aluminium foil varnish, electronic-chemical aluminum coating, UV surface treatment agent, UV primer,
Adhesive industry: heat-transfer printing gum, PTP aluminum foil glue(VC glue), glue for covering steel sheet with film, PVC glue, glue for row nails, glue for shoe materials,
Ink industry: silk-screen printing ink and transfer printing ink etc.
2. Solubility & Compatibility:
For YMCH resin, ketone solvents are specially suitable, such as ace-tone, MEK, nadone and isophorone.
Compared with ketone solvents, ester solvents have lower solubility for YMCH resin, such as methyl acetate, ethyl acetate and butyl acetate etc. Thus, we have to heat the solution or add ketone solvent into the solution while YMCH resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve YMCH terpolymer resin, but these kinds of solvent are toxic, they are only used in special situation.
YMCH resin is miscible with other resins during the course of using, 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.
3.Stability:
YMCH 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.
4. Packaging & Storage:
A. YMCH resin is usually packaged in the craft paper-plastic composite bag lined with plastic film according to 25Kgs per bag.
B. YMCH resin should be stored in dry place away from sunlight.
C. If YMCH resin has been kept over the shelf time, it shouldn’t mean the resin is invalid, but the user has to test the relevant properties of YMCH resin and its finished product before using it in bulk.
5. Others:
Any queries on technology or quality assurance can be inquired to our company.
6. Competitive Advantage:
Stable quality; More Competitive price; Timely and effective service; Shorter delivery time
