Common Chemicals Found in Paints and Their Functions
The chemical structure of MHEC mirrors that of HPMC. It encompasses hydroxyethyl groups linked to the hydroxyl groups within cellulose. The degree of substitution (DS) governs the quantity of hydroxyethyl groups incorporated, influencing MHEC's solubility, viscosity, and other intrinsic traits. MHEC remains stable under standard conditions and exhibits resistance to microbial degradation.
Factors such as air temperature, temperature and wind pressure will affect the volatilization rate of moisture in cement mortar and gypsum-based products. Therefore, in different seasons, the water retention effect of the same amount of HPMC is different.
