HPMC for Cement

Product Description

In cement-based products, cellulose ethers mainly play the role of water retention, adhesion and smoothing. To prevent cracks and dehydration caused by excessive water loss, they together enhance the adhesion of cement-based products, reduce sagging during construction, and make construction smoother.

Our medium viscosity products are used in cement-based products to improve water retention, hydrophobicity, processability, sag resistance, final consistency and productivity. Reduce primary and secondary weathering. Improves adhesion to various substrates.
