YMCH is used primarily for air-dry finishes, such as maintenance,
marine and metal coatings, aluminum foil varnish,cans sealed
paint,shoe adhesive,floor paint,cement paint,silk screen printing
and transfer ink. And it often is used in the production of heat
sealing packaging coatings, can effectively reduce the heat sealing
temperature, raise the heat sealing strength. It also can be used
to produce the VC sealing plastic package, Electro-chemical
aluminum paint, thermal transfer adhesive.
For YMCH resin, ketone solvents are specially suitable, such as
acetone, 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
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.
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
