One of the main benefits of using HPMC in wall putty is its ability to improve the tensile strength of the material. This helps to enhance the bonding of the putty to the wall surface, resulting in a smoother and more even finish. Additionally, the water retention properties of HPMC help to prevent the wall putty from drying out too quickly, allowing for a longer working time and reducing the likelihood of cracks or shrinkage.
The viscosity of a solution containing HEC is dependent on several factors, including the concentration of HEC, the molecular weight of the polymer chains, and the temperature of the solution. Higher concentrations of HEC and longer polymer chains typically result in a thicker solution

hydroxyethyl cellulose thickening mechanism. Additionally, HEC solutions are temperature-dependent, with higher temperatures leading to a decrease in viscosity due to the weakening of hydrogen bonds between the polymer chains.
