In the use of construction materials, hydroxypropyl methylcellulose is one of the more commonly used building material additives. Hydroxypropyl methyl cellulose is used in a wide range of industrial applications and comes in different types. Hydroxypropyl methyl cellulose can be divided into cold-water instant and hot-soluble types.
Cold-water instant HPMC can be used in putty powders, mortars, liquid glues, liquid coatings and daily chemical products. Hot-soluble HPMC is commonly used in dry powder products, where it is mixed directly with dry powder, such as putty powder and mortar.
Hydroxypropyl methylcellulose is widely used to improve the performance of hydrated building materials such as cement and gypsum. In cement-based mortars, it improves water retention, extends correction time and open time and reduces flow suspension.
Hydroxypropyl methyl cellulose can be used in the mixing of building materials in construction to enable dry mix formulations to be quickly mixed with water, agilely obtaining the required consistency for itself, and cellulose ethers to dissolve more quickly and without agglomerates.
Hydroxypropyl methyl cellulose can be mixed with dry powders in the construction of building materials and has the property of cold water dispersion, which allows the solid particles to be well suspended, making the mixture more delicate and homogeneous. It also enhances lubricity and plasticity and increases workability. It can make the construction of the product more convenient and easy. Enhanced water retention properties, more extended timeliness in working time and helps to block the draping of mortar, plaster and tiles. Extended cooling time promotes efficiency.
Hydroxypropyl methylcellulose improves the adhesive strength of tile adhesives and increases the crack shortening and crack strength of mortars and sheet caulks. Not only does it improve the air content of the mortar, significantly reducing its potential for cracking, but it also improves the appearance of the product and enhances the tile adhesive’s resistance to sagging.
