With the deterioration of the living environment of human beings, reducing environmental pollution and protecting the ecological environment have become a global concern. Laws and regulations on environmental protection in various countries are becoming more and more strict. In coating industry, whether in production or application, there are pollution problems. Promote the use of water-based coating is one of the better ways to solve this problem, water-based resin as the main raw materials of coating and its process for preparation of waterborne is to determine the speed the development of water-based paint.

    What are the properties of waterproof coatings?

    1. Solid content: solid content refers to the proportion of solid contained in waterproof coatings. The solid content of the coating is closely related to the film thickness and the quality of the coating due to the solid composition of the coating. Heat resistance refers to that the waterproof film after the waterproof coating film in high temperature does not soften deformation. Non-flowing performance, i.e. high temperature resistance.

    2. Flexibility: flexibility refers to the flexible performance of the film layer after the waterproof coating is made into film at low temperature. It reflects the construction and performance of waterproof coating at low temperature. Watertight watertight watertight watertight paint refers to the property of certain water pressure (static or dynamic water pressure) and no leakage within a certain period of time. It is the main quality index that waterproof coating meets waterproof function requirement.

    3. Elongation: the ability of stretch waterproof coating to adapt to deformation of base layer. Waterproof coating must have certain extensibility after film forming, in order to adapt to the deformation of base layer caused by temperature difference, dry and wet, and ensure waterproof effect.

    4. Thixotropy: in addition to strong surface tension and higher evaporation temperature, waterborne coatings also have certain thixotropy. The thixotropy of water-based materials refers to the change in the viscosity of water-based coatings due to external forces. For example, when mixing water-based materials, the viscosity of water-based coatings decreases.

    Water-based paint classification sometimes does not only on the strength of the nose to smell, when the choice, in order to ensure that can buy the real thing, a good approach is to offline store to buy, of course, must choose brand coating, especially find professional water paint, they produce more reassuring products, and more perfect after-sales service.
