Inorganic mineral coatings have obvious advantages in raw material composition, film formation mechanism and engineering application, making them a new type of interior and exterior wall coatings with market competitiveness.
According to reports, inorganic mineral coatings have five major advantages:
First, they are natural and non-toxic; the main components of inorganic mineral coatings are potassium silicate, inorganic pigments, mineral fillers, etc., and they are non-toxic. Toxic, odorless, non-irritating, and no harm to the environment and human health.
The second is: the coating film and the matrix are integrated; the main film-forming material of inorganic mineral coatings is alkali metal silicate, commonly known as water glass. Water glass is a silicic acid sol formed by the reaction between water-soluble inorganic compounds and carbon dioxide in the air. It can automatically penetrate into the wall matrix surface, causing the pigments, fillers and matrix to undergo silicification under the action of the curing agent and firmly combine into one, forming silicon. The oxygen chain structure is very similar to natural crystals, and its thermal conductivity is equivalent to that of the wall matrix. It is still heat-resistant and will not crack at temperatures exceeding 1000°C.
The third is: super durability; the use of inorganic mineral coatings has proven that in any climate, it does not need to be painted frequently and is durable for more than 15 years. Judging from engineering examples in Europe, it has been 20 years The above usage experience. Inorganic mineral coatings themselves are also fire-resistant, flame-retardant, light-reflective, non-fading, acid- and alkali-resistant, and do not breed fungi or algae.
The fourth is: it has excellent properties of breathability and water resistance; the inorganic mineral coating has excellent self-cleaning function and water resistance. The coating film, like human skin, neither permeates water nor can wick away "sweat", and can prevent water from penetrating. At the same time, it can evaporate and discharge the water in the matrix, keeping the matrix dry, and the coating film will not blister, turn yellow, or peel off.
Fifth: simple construction and easy operation. During construction, only the wall substrate is required to be flat, and there is no need to apply a primer layer. The coating is simple, convenient, easy to master, efficient and convenient, and can be applied by brushing, rolling or spraying.
