High-Performance White Powder HPMC for Enhanced Wall Putty Formulations
Tile adhesive:
Improves uniformity, makes mortar easier to spread, and improves resistance to sagging. Enhanced flow, thus improving efficiency.
High water retention, extending the working time of the mortar, improving efficiency, and facilitating the development of high mechanical strength during the setting period.
Air penetration is influenced by controlling the consistency of the mortar, thus eliminating micro-cracks in the coating and creating a high-quality surface finish.
The general chemical structure of MHEC is presented in Fig. 2. According to supplier information, the sample employed in the study exhibited a degree of substitution relative to methylation (DS value) of 1.81, and a molar degree of substitution relative to hydroxyethylation (MS) of 0.15. Gel permeation chromatography (GPC) analysis produced molar masses of 2.48·105 g/mol (Mw) and of 1.74·105 g/mol (Mn), respectively (Table 2). Using the GPC method, a hydrodynamic radius Rh(z) of 31.0 nm and a
