Dry mix mortar plays a crucial role in the construction industry, providing strength and durability to various structures. One key ingredient that enhances the properties of dry mix mortar is HPMC (Hydroxypropyl Methylcellulose). HPMC is a versatile additive that offers several benefits, including improved workability, increased adhesion, enhanced water retention, and better sag resistance. In this article, […]

1. Preparation-Mixed Concrete: HPMC is widely used in the production of ready-mix concrete to enhance workability and pumpability. It enables the transportation and placement of concrete over long distances without segregation or slump loss. Moreover, HPMC improves the workability of concrete surfaces, resulting in smoother and aesthetically pleasing finishes. 2. Mortar and Grouting: In mortar and […]

hot water solution method: because HPMC is not dissolved in hot water, so the initial HPMC can be evenly dispersed in hot water, then quickly dissolved when cooling, two typical methods are described as follows: 1) Put the required amount of hot water in the container and heat it to about 70℃. Under the slow […]

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 […]
