Fire retardant paint

Latex paints, clear oils or thinners appear cloudy and opaque due to the precipitation of insoluble matter, also known as turbidity, Mixed, mushy.

How does this happen?

Precipitates or precipitates when stored at low temperatures, or stored for too long.

The paint contains moisture. If the solvent contains moisture, or the moisture pours into the barrel during storage and transportation in the open air. The presence of moisture will promote the precipitation of the drier and cause turbidity.

Improper choice or excess of thinner. Since varnish is a colloidal substance, its storage stability mainly depends on the solubility of various film-forming substances in solvents. If the type of solvent is not selected properly, some paints are not easy to dissolve and will be cloudy. For example, the medium oil alkyd resin varnish is only diluted with 200# solvent gasoline, and it will become cloudy soon.

Improper selection of driers, especially lead driers, will varnish when there is a little moisture or low temperature become cloudy.

Inappropriate mixing of two components with different properties. If excessive lead drier is added to slow-drying varnish, the nitrogen content of nitrocellulose used in nitro varnish is too high, and the waxy content of shellac paint is too high, all of which are easy to cause turbidity.
