点击图片查看原图(1) emulsion polymer is dispersed in water, VOC is low, non-toxic, safe, and free from fire hazards.
2. The molecular weight of emulsion polymer is higher than 105, but the molecular weight is not related to viscosity. The film has a higher strength.
3.The viscosity of the system is low, so it can be pumped by pipeline in production, which can improve the efficiency of the preparation of latex coating.
(4) there is a special film forming mechanism. Emulsion is a water dispersive system. Its film formation is different from the homogeneous organic polymer solution system. It is a process of fusion with the evaporation of water through the compression deformation of particles, so it has certain permeability.
Emulsion polymers consist of small molecules, such as emulsifiers, initiators, buffers and so on, which are easily soluble in water and affect the water resistance and alkali resistance of the coatings prepared by the coating. This should not be ignored in the selection of polymers.
