SKP type quick-drying silica sol is a new type of quick-drying silica sol developed from silica sol gel and drying mechanism, it breaks the traditional theoretical binding of quick-drying silica sol, which is composed of many kinds of organic polymers and polymers. Scope of application: for precision casting surface layer, compared with ordinary silica sol, has the following advantages:

1. At the same temperature and humidity, compared with ordinary silica sol, the drying time can be reduced by more than 30% , greatly shortening the shell-making cycle.

2. No any organic polymer additives, so that paint stability is better, more environmentally friendly products, more friendly working environment.

3. Low residual strength of shell, easy to shell, improve the yield.
