HPMC is used in all types of aqueous paints and surface coatings.
The main application is in the production of water-based paints and the construction industry (production of dry building mixtures).
It can also be used in household chemicals, cosmetics, agricultural products, in the textile, chemical, tobacco and other industries.
Function:
1. HPMC is used as a thickening and water-retaining additive in the production of building and finishing materials (paints, putties, dry building mixes), including in the manufacture of adhesives for tiles, self-leveling floors and concrete products.
2. HPMC is the main modifying additive in almost all types of water-dispersion paints, putties. It is actively used in dry construction mixtures, due to its ability to retain water in the bulk of the solution, in particular, to slow the rapid transition of water to an absorbent base.
Advantages:
HPMC allows you to control the properties of water-dispersion paints, mortars based on cement, gypsum, latex and other binders.
Provides optimum stable viscosity during storage.
Improves consistency, stability and water retention in latex paints and other ready-to-use products.
Increases the manufacturability of mixtures, the adhesion of mortars.
Reduces shrinkage and cracking.
Method to use HPMC:
HPMC can be used both in dry form and in the form of an aqueous solution (2-3%).
HPMC mixes well with water, mixing for 15-20 minutes is enough for uniform swelling.
In the form of a dry powder, it is advisable to enter immediately after water, before the rest of the dry raw materials.
