The Russian construction industry has experienced a significant paradigm shift over the past decade, moving rapidly from traditional cement-sand site-mixes to advanced pre-packed dry-mix mortars. Among these, gypsum-based renders (known locally as "гипсовая штукатурка") have emerged as the absolute gold standard for interior wall finishing. This dominance is driven by Russia’s massive residential construction sector, particularly in key economic hubs such as Moscow, Saint Petersburg, Novosibirsk, and Yekaterinburg.
Gypsum renders are highly favored in the Russian market due to their excellent ecological profile, thermal insulation properties, and ability to regulate indoor microclimates by absorbing and releasing moisture. However, the performance of these gypsum-based systems is entirely dependent on the quality of chemical additives. This is where Hydroxypropyl Methyl Cellulose (HPMC) becomes indispensable. Without high-quality HPMC, gypsum mortars cannot retain the necessary water required for complete hydration, leading to premature drying, cracking, and structural failure on highly porous substrates like aerated concrete blocks, which are extensively used in Russian residential projects.
Furthermore, the Russian market places strict demands on the workability of plastering materials. Mechanized plastering, using advanced spraying machinery (such as PFT G4 or Kaleta systems), has become the standard practice for commercial developers in Russia. This technology requires gypsum renders to exhibit exceptional pumpability, prolonged open time, and high sag resistance. JINJI Chemical’s HPMC is specifically engineered to meet these requirements, ensuring that the dry-mix plaster flows smoothly through hoses without segregation and adheres perfectly to vertical walls and ceilings without slipping.
Since its establishment in 2002, our company has embarked on a 23-year journey of relentless growth and innovation within the global arena of specialty chemical additives. As a specialised manufacturer and supplier, we focus on producing advanced specialty chemical additives that are critical components in diverse industries, including cellulose ethers (HPMC, MHEC, HEC), redispersible polymer powder (RDP), HPS, PCE, CMC, PP fibre, etc.
Looking to the future, we are committed to leveraging our 23 years of technical and market insight to redefine industry benchmarks and ensure that our products meet our customers' expectations better.

JINJI CHEMICAL provides bespoke cellulose ether formulations tailored to specific client requirements. Whether adjusting viscosity, solubility, or thermal stability, our customization capabilities empower industries to achieve optimal results in their unique applications.
In the booming residential suburbs of Moscow and the surrounding Moscow Oblast, speed and surface quality are paramount. High-rise residential complexes utilize machine-applied gypsum plaster (механизированная штукатурка) to achieve level walls in record time. JINJI HPMC acts as a key rheology modifier, providing the plaster mix with the necessary lubricating properties to reduce friction inside the delivery hoses. This prevents machine blockages, reduces equipment wear, and ensures a uniform spray pattern. The sag-resistance properties provided by our HPMC allow workers to apply thick layers (up to 30mm) in a single pass without the plaster sliding down the wall.
In regions like Novosibirsk, Krasnoyarsk, and Yekaterinburg, extreme winter temperatures require interior walls to be highly insulated. Gypsum plaster is often applied over insulation boards or lightweight concrete blocks. During winter, interior heating systems are turned on high, creating dry indoor air that accelerates water evaporation from the wet plaster. JINJI's HPMC offers superior water retention (exceeding 98% even in warm or dry indoor drafts), ensuring that the gypsum plaster retains its moisture long enough to complete the chemical hydration process, preventing cracking and chalking at the edges.
Saint Petersburg is famous for its historical architecture, which requires delicate restoration. Historic brick substrates are highly porous and uneven. When restoring these buildings, the gypsum render must have long open times to allow craftsmen to replicate decorative moldings and achieve perfectly smooth finishes. JINJI HPMC extends the workability window of gypsum plaster, allowing plasterers to adjust and smooth the surface over a longer period without losing adhesion. This ensures a seamless bond between the old structural brickwork and the new decorative gypsum layer.
With the rising popularity of green building initiatives in Russia, developers are seeking low-VOC and non-toxic materials. Gypsum is inherently natural, and our HPMC, derived from natural plant cellulose, is an environmentally friendly additive. It does not release harmful volatile organic compounds during or after application, making it the ideal choice for premium, eco-friendly interior plasters destined for schools, hospitals, and modern green residential complexes.
The Russian dry-mix mortar market is moving towards specialization and digitalization. To stay competitive, local manufacturers are developing lightweight gypsum plasters (облегченная гипсовая штукатурка) containing perlite or vermiculite. These lightweight aggregates require HPMC with specific viscosity profiles to prevent segregation and maintain a stable air-void structure. JINJI Chemical is at the forefront of this trend, developing customized HPMC grades that optimize the distribution of lightweight aggregates, resulting in lighter plaster coats that are easier to apply and offer superior acoustic and thermal properties.
Our HPMC grades for gypsum renders are meticulously controlled for viscosity, particle size, and dissolution rate. We offer viscosity ranges from 30,000 to 75,000 mPa·s (Brookfield RV, 2% solution) to match different climatic conditions and application methods. The delayed-solubility treatment of our HPMC ensures that when the dry mix is added to water, the polymer dissolves uniformly without forming lumps, leading to a homogeneous plaster paste with optimal workability.
