  • In the world of coating applications, the choice of thickener can significantly impact both the performance and cost-effectiveness of the final product. Hydroxyethyl cellulose (HEC) has long been a popular choice, but its high price can pose challenges for manufacturers. On the other hand, Methyl hydroxyethyl cellulose (MHEC) emerges as a compelling alternative, offering superior thickening efficiency and cost-effectiveness. This article compares MHEC and HEC options, providing insights for optimizing formulations of water-based emulsion paints.
  • Cellulose is a polysaccharide, which means it is made up of multiple sugar molecules. In the case of cellulose, the sugar molecule is glucose. The linear arrangement of the glucose molecules in cellulose gives it its unique properties. Unlike other carbohydrates, cellulose is not easily broken down by enzymes in the human digestive system. This is why it is often referred to as dietary fiber and is important for maintaining healthy digestion.

  • The factors that affect the water retention of mortar also include cellulose ether viscosity, addition amount, particle fineness and use temperature.
    It is well known that the higher the viscosity, the better the water retention effect. However, the increase of viscosity means the increase of the added amount, but the higher the viscosity, the higher the molecular weight of HPMC, and the corresponding decrease in its solubility, which has a negative impact on the strength and construction performance of mortar. The higher the viscosity, the more obvious the thickening effect of mortar, but it is not proportional. The higher the viscosity, the stickier the wet mortar will be. During construction, the stickiness of the scraper and the substrate is high. But it is not helpful to increase the structural strength of the wet mortar itself. Therefore, it is not recommended to use this water retention method, which increases the cost and does not have a good effect.
    The larger the amount of cellulose ether added to the mortar, the better the water retention performance, the higher the viscosity, and the better the water retention performance.

  • The water retention capacity of HPMC is also beneficial in environments where moisture needs to be carefully managedhpmc for gypsum. In dry conditions, the additive helps to keep the plaster moist for longer, preventing it from drying out too quickly and ensuring that the chemical reactions required for proper curing can occur fully. This results in a stronger, more durable finish that can better withstand wear and tear over time.
