HPMC is een in water oplosbare, niet-ionische cellulose-ether die wordt geproduceerd door chemische modificatie van natuurlijke cellulose uit houtpulp of katoenlinters. Het biedt meerdere functionele voordelen — waterretentie, verdikking, filmvorming, binding en verbetering van de verwerkbaarheid — in één veelzijdig ingrediënt.
HPMC wordt geproduceerd door gezuiverde cellulose onder gecontroleerde alkalische omstandigheden te laten reageren met methylchloride en propyleenoxide. Dit proces introduceert twee soorten substituentgroepen op de cellulose-ruggengraat, die elk op verschillende manieren het prestatieprofiel van het eindproduct beïnvloeden.
Beheers de oplosbaarheid, thermisch gelatiegedrag en oppervlakteactiviteit van de cellulose-ether.
Beïnvloeden het waterretentievermogen, de viscositeitsontwikkeling en de compatibiliteit met andere ingrediënten.
De combinatie en verhouding van deze twee substituenten — uitgedrukt als de mate van methylsubstitutie (DS) en molaire substitutie van hydroxypropyl (MS) — bepalen het prestatieprofiel van de kwaliteit. Viscositeit, gemeten in een 2% waterige oplossing met behulp van Brookfield- of Ubbelohde-methoden, is de meest gebruikte parameter voor kwaliteitsselectie, variërend van minder dan 100 mPa·s tot meer dan 200.000 mPa·s, afhankelijk van de kwaliteit.
HPMC is niet-ionisch — compatibel met een breed scala aan additieven, oppervlakteactieve stoffen, zouten en pH-omstandigheden. Het is ook biologisch afbreekbaar, geurloos, smaakloos en vrij van dierlijke grondstoffen, waardoor het geschikt is voor gereguleerde en gevoelige toepassingen, van droogmengmortel tot farmaceutische hulpstoffen en voedselsystemen.

LANDERCOLL HPMC is available in multiple grade directions based on viscosity level, surface treatment, dissolution behavior, and target application. The information below is designed as a product selection reference. Final grade selection should always be confirmed through formulation testing and direct technical discussion with our team.
Delayed hydration — easier dispersion, reduced lumping, controlled dissolution. Preferred for drymix systems.
Faster viscosity development — quick hydration, suitable for fast-dissolving and direct-hydration formulations.
Note: Viscosity ranges listed above are approximate references. Actual LANDERCOLL HPMC grades should be selected according to your formulation, testing method, application environment, and required documentation. Contact our team for specific grade recommendations.
HPMC is a multifunctional cellulose ether. In most applications, it contributes more than one functional benefit simultaneously. Below is a structured overview of its primary functions across different system types.
In cement-based and gypsum-based systems, HPMC forms a polymer network that physically restricts water migration. Higher viscosity grades and higher dosage levels provide stronger water retention — preventing rapid water loss, incomplete hydration, and surface cracking.
HPMC dissolves in cold water to form a viscous, pseudoplastic (shear-thinning) solution. Viscosity decreases under shear during mixing and recovers at rest — supporting both processability and in-place stability across drymix mortar, detergents, personal care, and coatings.
In drymix construction materials, HPMC makes mortar smoother, more cohesive, and easier to spread, trowel, scrape, and finish. It is a combined result of water retention, viscosity building, and lubrication effects — particularly valued in tile adhesive, wall putty, and gypsum plaster.
Supports flow control, sag resistance, leveling behavior, and application stability. Prevents mortar from sliding on vertical surfaces, contributes to controlled flow in self-leveling compounds, and maintains stable viscosity in coatings and detergents.
HPMC forms a continuous, flexible film after water evaporation — used in pharmaceutical tablet coating, edible film systems, construction surface integrity, and selected water-based coatings as a binder component.
Supports structural integrity in tablet manufacturing, green strength in ceramics, and cohesion in drymix mortar. Also helps maintain uniform suspension of pigments, fillers, mineral powders, and active ingredients in coatings, detergents, and pharmaceutical systems.
HPMC grade selection should always start from the application. A grade optimized for tile adhesive will not necessarily perform well in a detergent, personal care, or pharmaceutical system. The table below provides a structured reference for common application-to-grade matching.

HPMC dosage depends on formulation design, raw material quality, target performance, ambient temperature, water quality, substrate type, and production process. The following ranges are general starting points for laboratory evaluation — not fixed usage standards.
For tile adhesive: 0.2%–0.5% is a widely referenced industry starting range. However, final dosage must be confirmed through laboratory testing and on-site performance evaluation, as substrate porosity, tile size, ambient temperature, and cement type all affect the optimal dosage.
| Toepassing | Typical Reference Dosage (% by weight) |
|---|---|
| Tegellijm | 0.2% – 0.5% |
| Muurplamuur / Skim Coat | 0.2% – 0.5% |
| Cementpleister | 0.15% – 0.4% |
| Gips | 0.1% – 0.3% |
| Metselmortel | 0.1% – 0.3% |

| Persoonlijke Verzorging | 0.1% – 1.0% |
| Watergedragen coatings | 0.1% – 0.8% |
| Food / Pharma / Specialty | Depends on grade, regulation, and formulation design |
These dosage ranges are general starting points. Adjust based on testing results under your specific formulation, raw materials, and application conditions.
Construction is the largest and most established application area for HPMC globally — a critical additive for water retention, workability, open time, and anti-sag performance.
In drymix mortar systems, HPMC functions simultaneously as a water-retaining agent, rheology modifier, and workability enhancer. Without HPMC, cement-based and gypsum-based mortars tend to lose water too quickly to the substrate, resulting in poor hydration, weak bond strength, surface cracking, and difficult application.
Water retention, open time extension, anti-slip behavior, and troweling feel. High to extra-high viscosity grades, 0.2%–0.5% dosage. Surface-treated grades commonly preferred.
Scraping smoothness, water retention, surface finish quality. Medium to high viscosity, 0.2%–0.5% dosage.
Controlled water retention without over-retarding set time. Smooth spreading, consistent texture, reduced surface defects. Medium to high viscosity grades.
Cement render, masonry mortar, self-leveling compounds, EIFS/ETICS, waterproof mortar, repair mortar, insulation mortar, joint fillers.
Home Care & Detergents
As a non-ionic polymer, HPMC is compatible with anionic and non-ionic surfactant systems commonly used in cleaning products. It builds smooth, stable viscosity that improves product appearance, pourability, and consumer perception — while helping maintain uniform suspension of insoluble components.

HPMC (CAS 9004-65-3) is used as a multifunctional cellulose ether additive across many industries. Its primary functions include water retention, thickening, workability improvement, film formation, binding, and formulation stabilization. Most widely used in drymix construction materials, and also in detergents, personal care, pharmaceutical excipients, food systems (E464), coatings, ceramics, and specialty industrial applications.
In tile adhesive, HPMC improves water retention to support cement hydration, extends open time to give installers more working time, provides anti-slip behavior to prevent tiles from sliding on vertical surfaces, and improves troweling feel and application consistency. High to extra-high viscosity grades are typically used, at dosages of 0.2%–0.5% of the dry mix weight.
Tile adhesive commonly uses high to extra-high viscosity HPMC, typically in the range of 50,000–200,000 mPa·s (measured at 2% aqueous solution). The exact viscosity grade depends on the formulation type, tile size and weight, required open time, anti-slip performance target, and application conditions. Final grade selection should be confirmed through formulation testing.
The typical reference dosage for HPMC in tile adhesive is 0.2%–0.5% by weight of the dry mix. This range is widely referenced in the drymix mortar industry as a starting point. However, the optimal dosage depends on the specific formulation, cement type, filler quality, target open time, water retention requirement, and application conditions. Final dosage must be confirmed through laboratory and field testing.
In wall putty and skim coat, HPMC improves water retention to prevent rapid drying, enhances scraping smoothness and surface finish quality, improves spreading behavior and workability, and helps maintain consistent product texture during application. Medium to high viscosity grades are typically used at dosages of 0.2%–0.5%.
HPMC uses hydroxypropyl groups while HEMC uses hydroxyethyl groups on the cellulose backbone, affecting water retention profile, dissolution behavior, and performance in specific applications. Both are used in tile adhesive, wall putty, and plaster. HPMC is more widely used across multiple industries including pharma, food, and personal care, while HEMC/MHEC is particularly established in European drymix construction markets.
