Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether made from refined cotton, a natural macromolecular material, through a series of chemical processing. It is widely utilized across industries including building materials, coatings, synthetic resins, ceramics, textiles, agriculture, and cosmetics.
In the construction industry, it serves as a critical additive for water-resistant putty powder, putty paste, tempered putty, paint glue, and thermal insulation mortar. It offers excellent water retention, improves construction ease, and provides good brightness. Viscosity and gel time parameters can be customized based on specific requirements.

While HPMC is generally recognized as safe, it is essential to handle it with care to maintain workplace safety:
Contains hydrophobic methoxy, allowing dissolution in organic solvents or water-organic mixtures.
As a non-ionic polymer, it remains stable in aqueous solutions of metal salts or organic electrolytes.
Provides emulsifying effects and protects colloids, ensuring relative stability in various formulations.
Effectively refined through hot water washing during preparation, resulting in extremely low ash levels.
High hydrophilicity maintains moisture in mortar, gypsum, and paint, preventing premature drying.
