Refractory coatings generally refer to cast coatings. The so-called cast paint (refractory paint) refers to the paint specially developed for the casting industry. The difference between the cast paint and the general paint is that the cast paint can withstand the molten metal or plastic at high temperature, and acts as a barrier between the casting and the mold to prevent adhesion. Generally speaking, mold coatings are made by suspending high melting point minerals or refractory substances in a liquid carrier. After coating the mold coating on the mold surface, the suspended cloud carrier disappears through evaporation or combustion, leaving a layer of refractory material on the mold sand surface. This refractory can prevent penetration, sand adhesion and sand washing or restrain it within limits, thereby improving the quality of the casting surface.

The coating is applied to sand or metal mold of cast iron and non-ferrous castings. After many tests, the coating not only has good performance and coating performance. There are also the following features:

(1) The coating has good suspension, no caking, not easy to mold, easy to stir;

(2) The coating has good thixotropy and rheology, strong adaptability;

(3) The coating strength of the coating is high, no cracking, no peeling, no moisture absorption tendency after curing, no deliquination deformation and strength reduction phenomenon;

(4) The paint has low gas generation and slow gas generation speed, which can reduce defects such as porosity in castings;

(5) The coating has strong sand resistance, high adhesion strength, easy peeling of the coating after pouring, high sand cleaning efficiency, and smooth casting surface

The above is a general introduction to refractory coatings, if you need to know more about Hubei Anaijie lining materials can tell you.
