Leveling agent is a common coating additive that can promote the production of a flat, smooth, and even polyurethane coating during the entire drying and gluing process of architectural coatings. A chemical substance that can reasonably reduce the interfacial tension of inorganic coating liquids and improve their leveling and uniformity. It can improve the hydrophilicity of inorganic coating liquid, reduce the probability of forming circular spots and scars during painting, enhance coverage, and make the adhesive uniform and natural.
Based on the different organic chemical structures, there are currently three key categories of leveling agents:
1、 Acrylic esters
2、 Organic silicon materials
3、 Fluorocarbon chemical substances
The key role of architectural coatings is decorative design and safety protection. If there are abnormal flow and leveling phenomena, it not only endangers the appearance, but also hinders the safety protection function.
If shrinkage occurs, resulting in insufficient thickness of the paint layer, and needle holes form discontinuities in the paint layer, these are all ways to reduce the protective effect of the paint layer.
During the construction and bonding process of building coatings, certain physical and chemical reactions will occur, which, along with the characteristics of the building coatings themselves, will significantly harm the flow and leveling of the building coatings.
