Tselluloos eetri tipptase — usaldatud enam kui 1000 ettevõtte poolt üle maailma Hangi tasuta proovi
LANDERCOLL tselluloos eeter aitab EIFS / ETICS mördi tootjatel parandada veepeetust, avatud aega, vajumiskindlust, töödeldavust ja pealekandmise stabiilsust välissoojustus- ja viimistlussüsteemides.
Usaldatud kuivsegumördi tootjate poolt üle Euroopa, Aasia ja Lähis-Ida välistermokrohvisüsteemide jaoks, mis nõuavad ühtlast värske mördi käitumist vertikaalsetel fassaadipindadel.
EIFS ja ETICS on välisseina soojustussüsteemid, mis on loodud parandama hoone energiatõhusust, fassaadi vastupidavust ja viimistluse kvaliteeti. Need süsteemid tuginevad mitmele mördi kihile, millest igaühel on spetsiifilised värske mördi jõudlusnõuded.
Mört peab soojustusplaadid kindlalt siduma, hoidma armeerimisvõrku paigal, jääma fassaadi paigaldamise ajal töödeldavaks ning vastu pidama vajumisele vertikaalpindadel.
LANDERCOLL tarnkab HPMC ja HEMC / MHEC tselluloos eetrit kuivsegumördi tootjatele, kes vajavad veepidavust, avatud aega, vajumisvastast jõudlust, siledat töödeldavust ja ühtlast pealekandmiskäitumist EIFS / ETICS kihtides.
Õige tsellulooseetri klass toetab värske mördi jõudlust ja aitab tagada sujuvama ning usaldusväärsema töökohal kasutamise isolatsiooniplaatide kinnitamisel, võrgu sissepaigaldamisel ja pinnaviimistlusel.
EIFS tähistab välist soojustus- ja viimistlussüsteemi. ETICS tähistab välist soojustuse komposiitsüsteemi. Mõlemad terminid kirjeldavad mitmekihilisi välisseina soojustussüsteeme, mis ühendavad soojustusplaadid, liimmördi, tugevduskihid, aluskihi, sissepõimitud klaaskiudvõrgu ning dekoratiiv- või kaitseviimistluskihid.
Neid süsteeme kasutatakse laialdaselt elamu-, äri- ja tööstusehituses soojuskadude vähendamiseks, fassaadi jõudluse parandamiseks ja kaasaegsete hoone energianõuete täitmiseks.
EIFS / ETICS konstruktsioonides kasutatakse tsemendipõhiseid kuivsegumörte isolatsiooniplaatide kinnitamiseks aluspindadele, klaaskiudvõrgu paigaldamiseks aluskihi kihtidesse, pindade tasandamiseks ja stabiilse aluse loomiseks viimistluskihtidele.
Tselluloos eeter mängib keskset rolli veepeetuse, avatud aja, reoloogia, vajumisvastase käitumise, kellutustunde ja märja mördi stabiilsuse kontrollimisel.
EIFS / ETICS mörte kantakse peale välisseintele ja vertikaalsetele isolatsioonipindadele erinevates kliimatingimustes. Need peavad jääma piisavalt kaua töödeldavaks, et tagada plaatide sidumine ja võrgu sissepressimine, säilitades samal ajal piisava struktuuri, et vältida vajumist pärast pealekandmist.
LANDERCOLL pakub HEMC / MHEC ja HPMC tselluloosi eetrite klasse isolatsiooniplaadi liimmördile, aluskrohvimördile, võrgu kinnitamise mördile, tugevdusmördile ja viimistluskrohvi süsteemidele.
HEMC / MHEC is particularly well-suited for EIFS / ETICS systems where extended open time, anti-sag performance, smooth troweling, strong water retention, and consistent workability are critical requirements.
In insulation board adhesive mortar, base coat mortar, and mesh embedding mortar, HEMC / MHEC helps maintain workable consistency over a longer application window and improves stability on vertical facade surfaces.
HPMC is one of the most widely used cellulose ethers in drymix construction materials and is suitable for a broad range of EIFS / ETICS mortar systems.
In adhesive and base coat systems, HPMC helps reduce rapid water loss to the substrate, supports smooth spreading during board bonding, and improves application comfort during facade installation.
EIFS / ETICS mortar formulations vary depending on insulation board type, system design, climate zone, target performance, and locally available raw materials.

The appropriate dosage depends on the specific mortar layer, target open time, anti-sag requirement, viscosity grade, polymer system, local climate, and job-site conditions.
Cellulose ether supports the key fresh mortar properties required for board bonding, mesh embedding, vertical stability, surface leveling, and durable facade layer formation.
Prevents mortar from losing moisture too quickly to substrate, insulation board surface, or surrounding environment. Adequate water retention supports cement hydration, open time, workable consistency, and stable layer formation.
Applicators need sufficient working time to position insulation boards, embed mesh, and adjust mortar layers before workability is lost.
Suitable HPMC and HEMC / MHEC grades improve wet mortar structure and yield stress on vertical exterior surfaces.
Improves rheology and spreading comfort, reducing applicator fatigue during facade installation.
Helps maintain open time and consistency for easier mesh placement, full coverage, and smooth finishing.
Improves wet mortar cohesion and reduces separation, uneven layer thickness, and inconsistent surface quality.
Supports smoother and more even base coat and finishing coat formation by improving consistency and water retention.
Many fresh mortar problems in EIFS / ETICS systems are related to water retention, rheology, and workability.
Rapid water loss, absorbent substrate, hot or windy conditions.

Understanding the variables that influence cellulose ether behavior helps formulators make better product and dosage decisions.
EPS, XPS, mineral wool, and other board types have different surface textures, absorption rates, and bonding requirements.
Cement type, filler quality, particle size distribution, and sand grading affect water demand and application feel.
Polymer powder influences adhesion, flexibility, durability, and compatibility with cellulose ether.
Adhesive, base coat, reinforcement, and finishing coat systems each have different rheology and open time requirements.
Viscosity affects water retention strength, workability profile, anti-sag behavior, and consistency.
Insufficient dosage leads to short open time; excessive dosage may cause stickiness or difficult spreading.
Temperature, humidity, wind speed, and sunlight exposure affect evaporation and open time.
Highly absorbent substrates draw water rapidly from fresh mortar and reduce workability.
Trowel application, board bonding, mesh embedding, spray application, and layer thickness affect flow and sag behavior.
Selecting the right cellulose ether requires balancing water retention, open time, anti-sag behavior, troweling comfort, mesh embedding workability, mortar consistency, and surface finish quality.

HPMC and HEMC / MHEC are the most commonly used cellulose ethers in EIFS / ETICS mortar systems. Both improve water retention, open time, anti-sag behavior, troweling performance, mortar consistency, and surface finish quality.
HEMC / MHEC improves water retention, extends open time, enhances anti-sag behavior on vertical surfaces, supports smooth mesh embedding, and maintains stable mortar consistency during application.
HPMC improves water retention, workability, mortar consistency, troweling comfort, and surface finishing quality in ETICS mortar systems.
Open time allows applicators to bond insulation boards, press them into position, embed reinforcing mesh, adjust layer thickness, and finish the surface before the mortar loses workability.
Yes. Suitable HPMC and HEMC / MHEC grades improve wet mortar yield stress and structural integrity, helping mortar resist sagging and slumping after application.
A common reference dosage range is 0.20%–0.50% by dry weight of the total mortar formulation, depending on mortar layer, polymer powder system, target open time, anti-sag requirement, and climate conditions.
Both are effective. HEMC / MHEC is often preferred for extended open time and strong anti-sag behavior. HPMC provides versatile water retention, workability, and surface finish support across multiple layers.
Start by identifying the mortar layer, insulation board type, polymer powder system, target open time, anti-sag requirement, application thickness, and local climate conditions.
Yes. Hot, dry, or windy conditions accelerate water evaporation, shorten open time, and reduce workability, so higher water retention grades or adjusted dosage may be needed.
Yes. LANDERCOLL can arrange HPMC and HEMC / MHEC samples for EIFS / ETICS formulation testing based on your mortar type, current formulation direction, and performance requirements.
Whether you produce insulation board adhesive mortar, base coat mortar, reinforcement mortar, mesh embedding mortar, finishing coat mortar, or polymer-modified EIFS / ETICS systems, LANDERCOLL can help you identify the right HPMC or HEMC / MHEC grade for better water retention, extended open time, improved anti-sag behavior, and reliable application stability.
