What is the main role of HPMC in the application of putty powder?
November 6th 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.
