Brief introductins-Construction grade HPMC for skim coat and gypsum plaster
The main function of hydroxypropyl methyl cellulose in dry building powder additives is to thicken and retain water. Although the cellulose added in dry building powder is not a lot, it only accounts for about four thousandths, but its role is comparative Importantly, the thickening and water-retaining effects of hydroxypropyl methylcellulose can enable workers to construct well during construction, and at the same time can appropriately increase the tensile strength and shear strength, greatly improve the construction effect, and enhance improve work efficiency.
HPMC chemical is a high viscosity product, for gypsum and cement based applications, such as gypsum plaster, tile adhesives etc,. It enhances water-retention, besides providing well-balanced properties including open time, slip resistance, adhesion, good impact resistance and shear strength.
