  • Answer: 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 stirring gradually add hydroxypropyl methyl cellulose, HPMC began to float on the surface of the water, and then gradually form a slurry, the slurry cooling under the stirring.
    2) Add 1/3 or 2/3 of the required amount of water into the container, and heat to 70℃, according to the method of 1), disperse HPMC, prepare hot water slurry; Then add the remaining amount of cold water to the hot slurry, stirring and cooling the mixture.
    Powder mixing method: HPMC powder and a large number of other powdery material ingredients, mixing fully with a blender, then add water to dissolve, HPMC at this time can dissolve, and do not stick together, because each small corner, only a little bit of HPMC powder, water will dissolve immediately. - Putty powder and mortar production enterprises are using this method. [Hydroxypropyl methyl cellulose (HPMC) is used as thickening agent and water retaining agent in putty mortar.]

  • Hydroxypropyl Methylcellulose (HPMC) is a vital ingredient in the construction industry, particularly in the formulation of building coating adhesives. It's a non-ionic, water-soluble polymer derived from cellulose, a natural polymer found in plant cell walls. The building coating adhesive sector has significantly benefitted from HPMC's unique properties, making it an indispensable component in modern construction materials.
  • The first step in preparing an HPMC solution is to accurately measure the amount of polymer needed. This can be done using a precision balance to ensure the correct amount is added. The polymer is then slowly added to the water, while stirring continuously to prevent clumping or uneven dispersion.

  • HPMC can be used in the manufacture of several baked products, fillings, foams and coatings. It is a great alternative for gluten substitution in gluten-free baked products in combination with CMC. 

  • The solubility of HPMC in cold water also depends on the degree of substitution. HPMC with a higher degree of substitution tends to have a lower solubility in cold water because the hydrophobic substituents (methyl groups) hinder the penetration of water molecules into the polymer network. On the other hand, HPMC with a lower degree of substitution has a higher solubility in cold water because the hydrophilic substituents (hydroxypropyl groups) facilitate the interaction between the polymer and water molecules.
  • The construction industry benefits from HPMC's water-retention capabilities. In concrete and mortar mixes, HPMC acts as a viscosity-enhancing agent, which helps maintain workability and reduces cracking during curing.
