Unleashing the Potential of HPMC in Gypsum Plaster and Beyond
October 22nd 2024
In the construction industry, MHEC powder is commonly used in products like tile adhesives, cement-based plasters, and mortars. Here’s how you can use it:
1. Tile Adhesives:
– Mixing: Add the required amount of MHEC powder to the dry mix of cement and sand. The typical dosage ranges from 0.1% to 0.5% by weight of the dry mix.
– Water Addition: Gradually add water while stirring continuously to avoid lump formation.
– Application: Apply the mixed adhesive to the substrate using a trowel. The MHEC enhances the open time, water retention, and workability of the adhesive.
2. Cement Plasters and Mortars:
– Mixing: Incorporate MHEC powder into the dry cement and sand mixture. The recommended dosage is usually between 0.1% and 0.4% by weight of the dry materials.
– Water Addition: Slowly add water and mix thoroughly to achieve a homogenous mixture.
– Application: Apply the plaster or mortar as usual. The MHEC improves the workability, adhesion, and water retention, resulting in better performance.
