Anti-Cracking Agents HPMC acts as an anti-cracking agent in coatings, reducing the risk of cracking and peeling due to temperature changes and other environmental factors. In the food industry, HPMC is used as a thickener, emulsifier, and stabilizer in various food products. It is commonly found in ice creams, sauces, dressings, and bakery products. HPMC helps improve the texture, mouthfeel, and shelf life of these products. It can also be used to create low-fat or low-calorie food formulations by replacing fats or sugars. When HEC is added to a liquid, the hydroxyethyl groups on the polymer chain interact with water molecules through hydrogen bonding. This interaction causes the polymer chains to swell and expand, forming a three-dimensional network that traps and immobilizes water molecules. As more HEC is added to the liquid, this network becomes denser, resulting in an increase in viscosity. Lastly, in paint manufacturing, MHE C-MHEC acts as a protective colloid that improves the flow and leveling properties of paints. It helps to create a uniform finish by reducing brush marks and improving spray atomization. Additionally, it increases the adhesion strength between the paint layer and the surface being coated, resulting in longer-lasting durability.
