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 […]

Hydroxypropyl Methylcellulose (HPMC) is a crucial ingredient in various industries, and ensuring its quality is paramount for achieving optimal results in applications ranging from pharmaceuticals to construction. In this article, we will explore how to judge the quality of HPMC simply and intuitively. Visual Inspection Color and Clarity One of the simplest ways to assess […]

In the ready-mixed mortar, the amount of cellulose ether added is very low, but it can significantly improve the performance of the wet mortar, which is a major additive that affects the performance of the mortar. Reasonable selection of different varieties, different viscosities, different particle sizes, different degrees of viscosity and the amount of added […]

1 water retention Hydroxypropyl methylcellulose HPMC for construction avoids moisture infiltration into the wall. The proper amount of water stays in the mortar, so that the cement has a longer time for hydration. The water retention is proportional to the viscosity of the cellulose ether solution in the mortar. The higher the viscosity, the better […]

The use of adhesives and sealants is widespread in various industries, from construction to automotive. These materials play a crucial role in bonding and sealing different surfaces, ensuring durability and reliability. One key ingredient that enhances the performance of adhesives and sealants is Methyl Hydroxyethyl Cellulose (MHPC). MHPC is a versatile additive that offers numerous […]

HEC (Hydroxyethyl Cellulose) and HPMC (Hydroxypropyl Methylcellulose) are both widely used in the paint industry as thickeners and rheology modifiers. While they share some similarities, there are also key differences in their properties and applications. One of the main differences between HEC and HPMC lies in their chemical structure. HEC is derived from cellulose through […]
