HPMC -MS Series
for Gypsum Mortar
HPMC (Hydroxypropyl Methylcellulose) is a water-soluble polymer used as a binder in gypsum based mortars. It is used to improve the workability, adhesion, and water retention of the mortar. HPMC is also used to reduce shrinkage and cracking, and to increase the strength of the mortar. It is also used to reduce the setting time of the mortar, allowing for faster application and drying time.
HPMC produced by ONLY® is used as an admixture in gypsum-based mortar.

Operability
The viscosity of MS Series is 50000mPa·S
After adding MS Series to the gypsum-based mortar, the mortar system does not sag and has a feeling of stretching.
Gypsum hand plaster (GHP) is used to render the interior of a building. MS Series provides good workability while securing strong adhesion between the plaster and the wall.
MS Series is specially designed for different kinds of Gypsum Based products, including Gypsum Adhesive, Gypsum Filler/Joint Filler, Gypsum Plasters, etc, to improve the required properties like Water Retention, Slip-resistance, Better Workability, Longer Open Time, Anti-crack property, Sag-resistance, Good Consistency etc.
Gypsum Special Grade HPMC
Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether obtained by cellulose alkalization, etherification, neutralization and washing.
HPMC has good thickening, dispersing, emulsifying, film-forming properties, etc. It is the first choice for production of high quality building materials additives.
Properties of Gypsum Putty HPMC
To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics. It is widely used in building base materials.It has good water retention and improve the workability. It can also prolong the open time and improve sag resistence.
Plaster plaster, bonding plaster, caulking plaster
Plaster materials are divided into whitewashed plaster, bonding plaster, and caulking plaster. Gypsum products have various different features. In addition to gypsum and related fillers, the key issue is that the added cellulose ether additives play a leading role. Since gypsum is divided into hydrated gypsum, anhydrous gypsum and semi-hydrated gypsum, different gypsum has different effects on the performance of the product, so thickening, water retention, and retardation determine the quality of gypsum building materials. The common problem of these materials is hollowing and cracking, and the initial strength cannot be reached. To solve this problem, it is to choose the type of cellulose and the compound utilization method of retarder. In this regard, hydroxypropyl methyl 30000-60000cps is generally selected, and the addition amount is between 1.5%-2%. It is water retention, retardation and lubrication. Notice to choose HPMC with high water retention.
HPMC water retention mechanism
HPMC is a polymer material with a three-dimensional network structure. There are many hydroxyl groups on the cross-linked network structure. The hydroxyl groups are hydrophilic groups. When it comes into contact with water, the hydrophilic groups will interact with water molecules. Combines into hydrogen bonds and absorbs large amounts of water through chemical adsorption.
