Features:
1, produced by solvent polymerization process, completely dissolved in organic solvents such as ketones and esters, with excellent solubility.
2. It has the high toughness and corrosion resistance of vinyl chloride and the strong viscosity and plasticity of vinyl acetate.
3. Soluble in pure ethyl ester.
3, high chemical stability, not affected by acid and alkali.
4. It is not easy and does not support combustion.
5. The thermoplasticity of resin makes the coating easy to heat seal. Hydroxyl modified resin can make it dry quickly.
7, strong compatibility, can be compatible with urea-formaldehyde resin, polyurethane, melamine resin and other coating resins.
8. Excellent dispersibility for organic pigments and inorganic pigments (such as azo dyes), enhancing the arrangement of silver powder.
9. If the resin contains hydroxyl and carboxyl groups, its characteristics can be improved by reacting with a bridging agent such as isocyanate. The functional group of hydroxyl group enables the resin to be crosslinked with thermosetting resin to obtain excellent chemical resistance (alcohol resistance) and water resistance.

Preparation method of chlorovinegar resin
1, bulk polymerization
Bulk polymerization is the polymerization process of monomer under the action of initiator or heat, light and radiation without adding other media. Its characteristics are pure products, no need for complicated separation and purification, simple operation and high production equipment utilization. It can directly produce high-quality products such as pipes and plates, so it is also called block polymerization.
2. Suspension polymerization
Suspension polymerization refers to the polymerization process in which monomers are dispersed into droplets and suspended in water under the action of mechanical stirring or oscillation and dispersant, so it is also called bead polymerization. The characteristics are: more water in the reactor, low viscosity of materials, easy heat transfer and control; After polymerization, resin products can be obtained by simple separation, washing, drying and other procedures, which can be directly used for molding; The product is pure and uniform.
3. Emulsion polymerization
Emulsion polymerization refers to the polymerization reaction in which monomers form emulsion in water with the aid of emulsifier under mechanical stirring or oscillation. The product of emulsion polymerization is latex, which can be used directly or washed and dried after destruction to obtain powder or needle-like polymer.
