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 […]

Method of use for hydroxypropyl methyl cellulose 1. Add the product to 1/3-1/5 of the required amount of hot water (80-90 ℃), stir and disperse until fully swollen, then add the remaining cold water and stir to cool down until fully dissolved. 2. The surface treated product can be directly dissolved in cold water with […]

1. Winter construction conditions and requirements For putty powder construction, the qualified base has five basic characteristics: firm, flat, dry, neutral and clean. For the construction conditions of putty powder, the construction ambient temperature must be controlled above 5 ℃ and the ambient humidity must be controlled within 85%, otherwise the construction is not allowed. […]

1. Redispersible emulsion powder can form a film after dispersion and play a reinforcing role as the second adhesive; The protective colloid is absorbed by the mortar system (it will not be destroyed by water after film formation, or “secondary dispersion”); The film-forming polymer resin is distributed in the whole mortar system as a reinforcing […]

Putty powder, commonly used in construction and renovation projects, is a versatile material known for its ability to fill gaps, smooth surfaces, and provide a base for painting or finishing. Hydroxypropyl Methyl Cellulose (HPMC) is a key ingredient in putty powder formulations, contributing to its adhesive and binding properties. Understanding the role and amount of HPMC in […]
