Eye paint is used to improve the adhesion of the topcoat, enhance its fullness, provide alkali resistance, and offer anti-corrosion properties; it also ensures even absorption of the topcoat, allowing the painting system to perform at its best. Improve the adhesion, corrosion resistance, alkali resistance, etc. of glasses frames. Do you know any other functions of paint for glasses? Below, the technical staff from Karl Technology will explain them to you! 1. Sealing: Some wall surfaces have a high alkalinity, and when exposed to moisture and water, alkali spots appear – scientifically known as \"efflorescence\". This condition causes crater-like protrusions on the surface of the paint coat; in severe cases, a layer of alkaline frost forms on the surface, ultimately leading to damage to the paint coat. Latex paint primer can provide a sealing effect to alleviate this situation. However, if the walls of your house are relatively dry and it’s on a higher floor, there might be no problem even without using it, but it’s recommended that you use it as a precaution. 2. Adhesion: The primer contains a high amount of emulsion, resulting in strong adhesion. It can improve the adhesion between the latex paint film and the wall surface. 3. Smoothing: If your wall surface is not highly alkaline and is relatively smooth, you can skip the primer; however, using one is still better. Applying a sealing primer before painting the glasses can not only save on renovation costs, but from a long-term and aesthetic perspective, using a primer also yields better results with less effort. At the same time, the good adhesion of the primer makes the wall surface smoother, facilitating the application of the topcoat and reducing the amount of topcoat needed. In this way, the wall is protected from paint defects and is better able to maintain its painted appearance for a longer period of time. The above is an overview of the other functions of glasses paint. Visit the website for more information: http://www.szkaer.com.
