In the world of construction, the use of additives is crucial to enhance the performance and quality of various materials. One such additive that has gained significant popularity in recent years is Hydroxypropyl Methylcellulose, commonly known as HPMC. This versatile compound offers a wide range of benefits and finds numerous applications in construction projects. One […]

Hydroxypropyl Methyl Cellulose (HPMC) is commonly used in the formulation of wall putty due to its various beneficial properties. Wall putty is a cementitious material used for filling cracks, leveling uneven surfaces, and providing a smooth finish to interior and exterior walls before painting. Here’s how HPMC is typically used in industrial wall putty formulations: […]

HPMC can effectively prevent the putty powder from falling off and cracking during use, because HPMC can enhance the internal bonding force of the putty powder, improve the adhesion and stability of the putty powder, thereby reducing the cracking problem caused by too fast evaporation of water. HPMC can increase the viscosity of the putty […]

HPMC has three functions of thickening, water retention and construction in the application of putty powder. Thickening: cellulose can thicken, play a role in suspension, keep the solution uniform up and down, and resist sagging. Water retention: make putty powder dry slowly, and assist lime calcium to react under the action of water. Construction: cellulose […]

1.Water-Holding Capacity Hydroxy Propyl Methyl Cellulose (HPMC) helps to significantly improve the water-holding capacity of mortar. Just a low level of hydroxypropyl methyl cellulose addition can lead to a significant improvement in the water retention rate of the mortar. When the addition level is 0.002%, the water retention rate increases from 83% to 88%; while […]

Improved Workability HPMC improves the consistency and ease of application of construction materials, making them easier to spread and apply. Enhanced Water Retention It significantly increases the water retention capacity of cement and gypsum-based products, preventing premature drying and improving the curing process. This leads to better strength development and reduced risk of cracks. Increased […]

HPMC solubility in water has two types: surface-treated HPMC and non-surfaced treated HPMC. 1 Solubility of Surface-Treated HPMC in Cold Water When surface-treated HPMC is added to cold water, it disperses into the water without exhibiting any viscosity. After stirring and waiting for approximately 2 minutes, the solution thickens and becomes viscous. This is attributed to […]

1. Mortar and cement-based products A. Improve workability HPMC is often added to mortars and cement-based products to improve workability. It acts as a water retaining agent, preventing rapid loss of water during the setting process. This results in better maneuverability and easier application. b. Increase adhesion Adding HPMC to mortar improves adhesion to a […]

● Water Retention Water retention is an important property of HPMC. The viscosity, dosage, environmental temperature and molecular structure of HPMC have a greater impact on its water retention performance. Under the same conditions, the higher the viscosity of HPMC, the better the water retention; The higher content, the better the water retention. Generally, a small […]
