Engineered for wall putty, skim coat, tile adhesive and beyond — JINJI CHEMICAL's cellulose ether portfolio delivers measurable performance improvements across every application.
As a leader in high-performance specialty chemicals, JINJI CHEMICAL develops and manufactures advanced additives critical to modern construction. Our core products range features cellulose ethers (HPMC, MHEC, HEC), which are essential for optimizing water retention, workability and adhesion, as well as for increasing viscosity and thickness in dry-mix mortars — including tile adhesive, wall putty, cement render and self-leveling mortar — as well as in detergents and water-based paints.
Complementing these, our Redispersible Polymer Powder (RDP) enhances flexibility and bond strength in cementitious systems. From HPMC for tile adhesive to RDP for mortar, JINJI provides tailored solutions that elevate durability, efficiency, and sustainability across global construction projects — where science meets application mastery.

Strict quality control processes ensuring every batch meets international performance benchmarks for wall putty and skim coat applications.
Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic, water-soluble cellulose ether produced through the chemical modification of natural cellulose with methyl and hydroxypropyl groups. It forms a clear, viscous solution in cold water and exhibits unique thermal gelation properties — making it an indispensable additive in construction dry-mix formulations, especially wall putty and skim coat.
In wall putty and skim coat applications, HPMC functions as a multi-performance additive: it simultaneously controls water retention, modifies rheology, extends open time, and enhances adhesion to substrates including concrete, brick, gypsum board, and AAC blocks. Without HPMC, putty formulations would dry too quickly, crack, delaminate, or lose workability in hot or dry conditions.
Unlike starch ethers or polyvinyl alcohol alone, HPMC delivers superior consistency across a broad temperature range (5°C–40°C), making it the global standard for interior and exterior wall finishing systems. Its biopolymer backbone provides inherent stability against microbial degradation while meeting increasingly stringent green-building certifications such as LEED and BREEAM.
JINJI CHEMICAL's advanced HPMC products optimize water retention, enhance adhesion, and ensure consistent workability for vertical and horizontal substrates. Our products deliver precision flow control for seamless leveling, superior crack resistance in finishing layers, and stabilized rheology in liquid systems.
HPMC grades specifically engineered for interior and exterior wall putty deliver exceptional water retention (≥98%), extended open time up to 40 minutes, and excellent smoothability — achieving a mirror-like finish surface ready for painting or wallpaper.
In tile adhesive, HPMC provides the critical balance of slip resistance, open time, and tensile bond strength. Prevents tile slippage on vertical surfaces — essential for high-rise façade installations in extreme climates.
Precise rheology modification enables pumpable, self-leveling floor screeds that achieve flatness tolerances of ±2mm over 2 meters — meeting the demands of industrial flooring, clean rooms, and luxury residential projects.
MHEC and HPMC in render systems control spray consistency and sag resistance in machine-applied and hand-applied plasters. Proven performance in tropical humidity and desert heat conditions.
HEC and HPMC provide viscosity stabilization and anti-redeposition properties in liquid and powder detergents. Maintains consistent performance in hard water conditions and high ambient temperatures.
As a rheology modifier in architectural and industrial coatings, HPMC and HEC control sag, leveling, and brush drag — enabling VOC-compliant, high-build decorative finishes over wall putty base layers.
The global HPMC market for construction applications is projected to surpass USD 2.8 billion by 2030, driven by rapid urbanization in Asia-Pacific, the Middle East, and Africa. Here are the key trends reshaping the wall putty and skim coat segment.
India, Southeast Asia, and Sub-Saharan Africa are witnessing unprecedented construction activity. Government housing programs like India's PM Awas Yojana are driving demand for high-performance, cost-effective wall putty formulations that require premium-grade HPMC to meet quality standards at scale.
As LEED, BREEAM, and China's Green Building Standard gain traction, formulators are replacing synthetic polymers with bio-based cellulose ethers. HPMC's plant-derived origin and biodegradability position it as the preferred choice for eco-certified construction projects globally.
The shift toward mechanized spray plaster systems (Knauf, BNBM, local OEMs) demands HPMC grades with precisely controlled viscosity, dissolution speed, and sprayability. JINJI's engineered grades are optimized for pump-applied wall putty systems operating at 60–120 bar pressure.
With climate zones becoming more extreme, demand for HPMC grades that maintain performance at temperatures from -5°C to +50°C is growing. Our thermal-stable formulations prevent summer blistering and winter cracking — critical for Middle East and North Africa markets.
The global shift from site-mixed to factory-produced dry-mix mortars is accelerating. This industrial transition multiplies HPMC consumption volumes, with top dry-mix mortar manufacturers consuming thousands of metric tons of cellulose ether annually in wall putty formulations.
One-size-fits-all HPMC is obsolete. Market leaders now demand application-specific grades optimized for gypsum vs. cement systems, interior vs. exterior applications, and machine vs. hand application — driving JINJI's continued investment in R&D and grade diversification.
The most common application globally, interior white cement putty incorporates HPMC at dosages of 0.2–0.4% by weight. At this concentration, HPMC provides:
Exterior skim coats demand higher performance: UV resistance, rain wash-out resistance, and adhesion to EPS foam insulation boards. HPMC (typically combined with RDP at 2–5%) provides the rheological backbone while RDP contributes flexibility and waterproofing. JINJI's exterior-grade HPMC is specifically designed with delayed dissolution to prevent surface skins in warm conditions.
In markets where fast-track construction timelines are critical — such as government housing projects, hospitality chains, and commercial fit-outs — gypsum-based skim coats with MHEC or HPMC additives offer 2–4 hour set times while maintaining a workable consistency for up to 90 minutes. This "long open time, fast set" performance is uniquely enabled by cellulose ether technology.
Autoclaved Aerated Concrete (AAC) blocks — widely used across India, China, and the Middle East — are highly porous and water-absorbent. Standard putty without HPMC would lose water too rapidly, failing to achieve proper adhesion. High water-retention HPMC grades (≥200,000 mPa·s) are the solution, ensuring the putty maintains moisture content long enough for complete cement hydration and bond development.
