Product Description
Hydroxypropyl methylcellulose (HPMC)
Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose made from natural polymer materials through a series of chemical processes.Containing almost all the properties of methylcellulose (MC), it is your first choice for producing high-quality building materials additives
Features of HPMC
In order to meet the needs of environmental protection, our products have the characteristics of high water retention, good dispersion, good fineness, good workability, and easy dissolution.It is suitable for building dry mortar, interior and exterior wall putty powder (paste), adhesives, caulking agents, interface agents, coatings, and new building material self-leveling agents.

applicatio
HPMC can be used as building additives such as dry mortar, tile adhesive, wall putty, putty, self-leveling, tile caulking agent, etc. It has excellent properties such as high water retention and long opening time, which can improve the performance of building construction.work capacity and cost savings.
Tile glue
1.With HPMC, tile adhesive mixes easily with water, won't clump, and saves time.Because operations are faster and more efficient, we can increase operability and reduce costs.
2.The water-retaining properties of HPMC extend the drying time of the mortar, thereby improving the fixing efficiency.
3.HPMC provides good bonding effect and high slip resistance.
Cement based plastering mortar
1.HPMC can improve the uniformity of plastering mortar, making it easier to apply, while improving its resistance to sagging.It can also improve the fluidity and pumpability of mortar and improve work efficiency
2.HPMC has high water retention, which can extend the working time of mortar, improve work efficiency, and help the mortar obtain high mechanical strength during solidification.
3.HPMC can control air penetration and eliminate micro-cracks in the coating to create an ideal smooth surface.
masonry mortar
1.HPMC can improve the bonding force between mortar and masonry.The water retention performance of HPMC is beneficial to improving the strength of mortar.
2.HPMC improves the lubricity and plasticity of mortar, thereby making construction easier, saving time and reducing costs.
crack filler
1.The excellent water retention of HPMC can extend the drying time of the caulking agent, which is beneficial to improving work efficiency.In addition, high lubricity makes construction easier and smoother.
2.HPMC can improve the shrinkage and crack resistance of filling materials, making the surface quality more perfect.
3.HPMC makes the construction surface delicate and smooth.At the same time, adhesion is also improved.
Gypsum-based plasters and gypsum products
1.HPMC can improve the uniformity of plastering mortar, making it easier to apply, while improving its resistance to sagging.It can also improve the fluidity and pumpability of mortar and improve work efficiency.
2.HPMC has high water retention, which can extend the working time of mortar, improve work efficiency, and help the mortar obtain high mechanical strength during solidification.
3.HPMC can maintain a uniform consistency and form a good surface.
Self-leveling floor materials
1.The viscosity of HPMC has an anti-settling effec
2.HPMC can enhance the flow and pumpability of the product, thereby improving the efficiency of floor usage.
3.The water retention of HPMC prevents excess air from infiltrating.As a result, cracks and shrinkage are greatly reduced.
Water-based paints and paint strippers
1.The suspending properties of HPMC can extend shelf life by preventing solids from settling.It also has good compatibility and biological stability with other ingredients.
2.HPMC helps products dissolve quickly without clumping.
3.HPMC gives the paint good flowability and low spatter, resulting in a fine, smooth surface.
4.HPM can increase the viscosity of paint stripper to keep it within the working range.
