99.5% UNID Potassium Carbonate for Paintings, CAS 584-08-7 K2CO3 for Carbonate of Potash in Coatings
1. Potassium Carbonate K2CO3 Introduction
Potassium carbonate is a inorganic compound substance with chemical formula K2CO3 and molecular weight of 138.206. It is a white crystalline powder with a density of 2.428g/cm3 and a melting point of 891 ℃. It is easily soluble in water, and the aqueous solution is alkaline. It is insoluble in ethanol. Potassium carbonate has strong hygroscopicity. When exposed to the air, it can absorb carbon dioxide and water, which can be converted into potassium bicarbonate. We have exported potassium carbonate to mainly countries such as Mexico, Kazakhstan, Egypt, etc.

3. Potassium Carbonate K2CO3 Applications
4. Potassium Carbonate K2CO3 Functions in Paintings /Coatings
The role of potassium carbonate in paintings mainly includes adjusting pH value and increasing coating hardness and durability. Potassium carbonate, as a neutralizing agent, can neutralize acidic substances in coatings, keeping the pH value within an ideal range, thereby improving the stability, adhesion, and durability of coatings. In addition, potassium carbonate can react with calcium ions in coatings to generate stable calcium carbonate precipitates, thereby increasing the hardness and durability of coatings.
The specific application of potassium carbonate K2CO3 in paintings/coatings.
Adjusting pH value: The pH value of a coating has a significant impact on its performance and quality. Potassium carbonate can be used as a neutralizing agent to neutralize acidic substances in coatings, keeping the pH value within an ideal range, thereby improving the stability and adhesion of coatings.
Increasing coating hardness and durability: Potassium carbonate K2CO3 reacts with calcium ions in the coating to generate stable calcium carbonate precipitates, thereby increasing the hardness and durability of the coating. In addition, potassium carbonate can also reduce the sodium content in the coating, avoiding discoloration and corrosion of the coatings.
