Applications:
DY-4 is mainly applied in the following many fields:
PVC ink, paper ink, PVC adhesive, additive for PVC modification, strippable coating, leather treatment agent, electric cable material, pigment paste and flake for PU, thermal insulating foaming material, calcium-plastic floor, etc.
Solubility And Compatibility:
Ketone solvents are especially suitable for DY-4 type of bipolymer, such as acetone, MEK, nadone and isophorone.
Ester solvents have lower solubility for DY-4 resin, such as methyl acetate, ethyl acetate and butyl acetate etc, so we need to heat the solution or add ketone solvents into the solution while DY-4 resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve DY-4 bipolymer, but these kinds of solvent are toxic, they are only used in special situation.
DY-4 bipolymer is miscible with following resins during the course of using:
Many 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:
DY-4 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 stabilizer, light resistant ultraviolet stabilizer.
Packaging and Storage:
1. DY-4 resin is usually packaged into the craft paper-plastic composite bag lined with plastic film according to 25Kgs / bag.
2. Stored in dry place away from sunlight.
Others:
If DY-4 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 DY-4 resin and its finished product before using it in bulk.Any queries on technology or quality assurance can be inquired to our company.
Advantage:
1. Better quality in the industry
2. More competitive price in the world market
3. Timely and effective service
4. Shorter lead time
