Packaging and Storage:
1. Packaged into the craft paper-plastic composite bag lined with plastic film
2. 25Kgs per bag.
3. Stored in dry place away from sunlight.
Applications:
DY-3 is principally used for:
A. PVC ink, silk-screen printing ink, paper ink,
B. strippable coating, leather treatment agent, transfer printing coating,
C. PVC adhesive,
D. electric cable material, pigment paste and flake for PU,basic material of magnetic card, thermal insulating foaming material, additive for PVC modification, calcium-plastic floor, coating etc.
Solubility:
For DY-3 resin, ketone solvents are specially suited, such as ace-tone, MEK, nadone and isophorone.
Ester solvents have lower solubility for DY-3 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-3 resin is dissolved in ester solvents.
Chlorohydrocarbons, Nitro compound and alicyclic solvents, such as dichloroethane and diethylene oxide, also can dissolve DY-3 type of bipolymer, but these kinds of solvent are toxic, they are only used in special situation.
Stability:
DY-3 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.
Compatibility:
DY-3 polymer resin is miscible with other resins during the course of using, such as other types of vinyl chloride vinyl acetate copolymer, PVC resins, perchloro-ethylene resin, ketone resins, chloroprene rubber, NBR, polyacrylate, epoxy resin, polyester and petroleum resin etc.
Competitive Advantage:
More appropriate price under the same quality as the one out of China.
Timely and effective service based on quality and technic.
Shorter lead time based on requirements from clients
Others:
A. Any queries on technology or quality assurance can be inquired to our company.
B. Should DY-3 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 DY-3 resin and its finished product before using it in bulk.
