1. What is the Emulsion
An emulsion is a mixture of two immiscible substances. One substance (the dispersed phase) is stably dispersed in the other (the continuous phase) by a dispersed effect of the surfactant.
2. Comparison of particle size
3. Characteristic of polymer emulsion
4. Characteristic of polymer emulsion
5. Physical and General properties of emulsion
Physical properties of emulsion
Solid content, Viscosity, pH,
Free monomer, Grits, Particle size,
Particle size distribution, Sedimentation,
Toluene insoluble parts, Tg, MFT
General properties of emulsion
- Safety (because the medium is water)
- Thixotropy fluid.
Share -> Low Viscosity
No share -> High Viscosity - Film formation
6. Purpose to use ethylene as monomer for copolymerization
- Internal plasticity effect
- Various polymer design
- Excellent water proof & alkaline resistance
- Excellent weather resistance
- Affinity with non-polarity material
(ex. plastic and synthetic material, etc.)
