Varnishes are a large group of coating materials for various surfaces. The purpose of the film-forming agent in natural solvents or water is to protect against moisture, pests and climate change. The clear coat improves the appearance of the surface, making it shiny and smooth.
Main types of varnish
The variety of paints and varnishes can be roughly divided into three categories:
- bituminous;
- oil;
- alkyd.
Oil varnishes are made from natural resins and artificial solvents. The basis is often rosin, amber and shellac. In India, there is a huge list of resins, on the basis of which they create paints for painting. These varnishes are very expensive, so they are of limited use. Used for interior decoration, furniture manufacturing and restoration.
Alkyd varnishes are the most common household varnishes. All of them are transparent and are solutions of alkyds in natural solvents. The material protects well from water, is relatively cheap, is well applied to any surface and, in general, surpasses oil varnishes in its properties.
