At this stage, many buildings and public places have begun to use Lixin concrete sealing and curing agent to strengthen the performance of the floor. However, after the construction, some people react that the performance of the floor after construction is fundamentally different from what they said before, and the hardness, anti-seepage and gloss are not all good.

The film-forming material of anti-corrosion coating has chemical stability in corrosive medium, and its standard is related to the composition and chemical structure of film-forming material. It mainly depends on whether it is easy to react with corrosive medium or decompose into small molecules in the medium under dry film conditions.

The anti-corrosion coating is a coating formed after drying and curing on the surface of the substrate to be coated. Its protective effects mainly include the following three types: shielding effect. According to the principle of electrochemical corrosion, the corrosion of steel must have the existence of oxygen, water and ions, as well as the way of ion flow and conduction. The paint film prevents the existence of corrosive medium and material surface, Blocking the path of the corrosive battery increases the resistance. The penetration rate of water, oxygen and ions to the paint film is different. The penetration rate of water is much higher than that of ions and oxygen. There is less direct penetration of the paint film, so their direct effect on the substrate metal can be ignored.

At present, there are three kinds of synthetic resin paints with excellent properties - polyurethane varnish, polyester varnish and acrylic varnish. Polyurethane varnish is a new type of interior coating with excellent performance. Due to the thick film and high solid content, the paint film looks like glass after drying. Some people call it "glass paint", also known as "resin paint".
