Water based polymer varnish - Characteristics (1) Emulsion polymers are dispersed in water, volatile organic compounds are low, non-toxic, safe and free from fire hazards. (2) The molecular weight of emulsion polymer is relatively high, and the relative molecular mass can reach more than 105. However, the molecular weight is not related to viscosity. It has high film strength after film formation. (3) The viscosity of the system is low, which can be pumped by pipeline in production, so as to improve the efficiency of latex coating processing and preparation. (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. (5) The composition of emulsion polymer contains emulsifier, initiator, buffer and other small molecule compounds. It is easy to dissolve in water, and has an effect on the water resistance and alkali resistance of the film prepared by coating. This cannot be ignored in the selection of polymers. Water based white varnish takes water as the dispersion medium. It can be diluted with water during the printing process. The equipment can be cleaned with water. It will not produce harmful gases containing aromatic hydrocarbons. It is not easy to burn and explode. It is very safe in production and storage. Solvent based varnish can be divided into aromatics and alcohols. Aromatic varnish contains a lot of benzene harmful substances, which will seriously damage the health of operators and pollute the environment in the printing process, and it is flammable and explosive; Alcohol varnish has relatively low toxicity, but it also has the problem of flammability and explosion, and the safety problem in the production process is more prominent.Water Based Polymer price website:http://www.kageminks.com/water-based-polymer/
