The advanges of HPMC & MHEC in dry mix mortar products
November 22nd 2024
Hydroxypropyl methyl cellulose (HPMC) is a water-soluble cellulose ether that is commonly used as a thickener, water retention agent, and stabilizer in a variety of construction applications, including tile adhesive mortar and plaster gypsum. It is a versatile and effective additive that can improve the performance of these materials in several ways.
Benefits of HPMC in Tile Adhesive Mortar and Plaster Gypsum
Water Retention: HPMC can significantly increase the water retention capacity of tile adhesive mortar and plaster gypsum, which helps to prevent premature drying and cracking. This is especially important in hot and dry climates or when working with porous substrates.
Workability: HPMC improves the workability of tile adhesive mortar and plaster gypsum, making them easier to mix, apply, and spread. This can lead to a smoother finish and better adhesion to the substrate.
Adhesion: HPMC enhances the adhesion of tile adhesive mortar and plaster gypsum to the substrate, resulting in a stronger bond and reduced risk of delamination or failure.
Open Time: HPMC extends the open time of tile adhesive mortar and plaster gypsum, giving installers more time to adjust the position of tiles or make other adjustments before the material sets.
Slip Resistance: HPMC imparts slip resistance to tile adhesive mortar and plaster gypsum, reducing the risk of tiles sliding out of place or plaster slumping.
Recommended Dosage of HPMC
The recommended dosage of HPMC for tile adhesive mortar and plaster gypsum typically ranges from 0.1% to 1% by weight of the dry powder. The specific dosage will depend on the desired properties of the material and the application conditions.
