The redispersible latex powder product is a water-soluble redispersible powder, divided into copolymers such as ethylene/vinyl acetate, vinyl acetate/tertiary carbonate ethylene, and acrylic copolymers. It is a powder adhesive produced by spray drying, with polyvinyl alcohol serving as a protective colloid. This powder can quickly redisperse into an emulsion upon contact with water. Due to its high […]

In the dynamic world of construction materials, the quest for solutions that balance workability and durability is ever-present. One remarkable innovation that has garnered attention in recent years is the integration of HPMC for Gypsum. This powerful combination has a profound impact on both the workability during application and the overall durability of gypsum-based products. In […]

Redispersible polymer powder is a versatile and crucial component in the construction industry, especially in the formulation of mortar and cement products. Its use contributes to the enhancement of various properties, leading to high-quality and durable construction materials. Here are some key aspects of how redispersible polymer powder serves as a vital ingredient in mortar and […]

Choosing the right Hydroxypropyl Methylcellulose (HPMC) for cement-based putty applications is crucial, as different HPMC grades can have varying properties that directly impact the performance of the putty. Here are key considerations highlighting the importance of selecting the appropriate HPMC: Viscosity and Rheology: Different HPMC grades exhibit varying viscosity levels and rheological behaviors. The viscosity of HPMC influences the workability […]

Hydroxypropyl methylcellulose (HPMC) is a versatile and valuable additive in the construction industry with a wide range of advantages in a variety of applications. As a chemical engineer, it is critical to understand the specific advantages HPMC brings to construction materials and how its unique properties can help improve the performance, processability and durability of […]

Hydroxypropyl Methylcellulose (HPMC) is a versatile additive commonly used in the construction industry, including in dry mix mortar formulations. HPMC enhances the performance of dry mix mortar in several ways: Water Retention: HPMC acts as a water-retaining agent, helping to prevent the rapid evaporation of water from the mortar mix. This is particularly crucial during the […]

Hydroxypropyl methyl cellulose is widely used in daily chemical washing industry, construction industry, textile industry, etc. This article provides a brief introduction to the purpose of HPMC. Hydroxypropyl methyl cellulose is used 1, water product thickener. Used for laundry detergent, hand sanitizer, shampoo, dishwashing liquid, detergent, etc. HPMC mainly increases the viscosity, transparency and bubble […]

The relationship between water retention and viscosity of hydroxypropyl methylcellulose is not a proportional relationship within a certain viscosity range, but also depends on the practical application of the product. Relatively speaking, when hydroxypropyl methyl cellulose has a viscosity of more than 100,000, the difference in water retention between 100,000 viscosity and 200,000 viscosity is not large. Analysis of […]

A: Hot water dissolution method: Since HPMC does not dissolve in hot water, HPMC can be evenly dispersed in hot water at the initial stage, and then quickly dissolved when cooled. Two typical methods are described as follows： 1），Add 1/3 or 2/3 of the required amount of water into the container and heat it to […]
