The advanges of HPMC & MHEC in dry mix mortar products
November 22nd 2024
Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether widely used as an additive in gypsum plaster. It offers several benefits to the overall performance of the plaster, including:
Improved Water Retention: HPMC acts as a thickener and water retention agent, prolonging the setting time of the plaster. This allows for better workability and prevents the plaster from drying too quickly, which can lead to cracking.
Enhanced Workability: HPMC increases the plasticity of the plaster, making it easier to apply and spread evenly. This reduces the amount of effort required for troweling and finishing, saving time and labor costs.
Increased Bond Strength: HPMC improves the adhesion of the plaster to the substrate, resulting in stronger and more durable bonds. This is especially important for applications where the plaster will be subjected to heavy wear and tear.
Reduced Cracking: By preventing the plaster from drying out too quickly, HPMC helps to minimize cracking. This is crucial for achieving a smooth and aesthetically pleasing finish.
