JINJI CHEMICAL's core cellulose ether portfolio is engineered for water-based paints, coatings, and construction applications — delivering consistent performance globally.
As a leader in high-performance specialty chemicals, JINJI CHEMICAL develops and manufactures advanced additives critical to modern construction and industrial applications. Our core product range features cellulose ethers — HPMC, MHEC, and HEC — which are essential for optimizing water retention, workability, and adhesion, as well as for increasing viscosity and thickness in dry-mix mortars, 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.
Sustainability First: HPMC is derived from natural plant cellulose, making it an eco-friendly thickener that aligns with global green building standards and low-VOC coating regulations.
Hydroxypropyl Methyl Cellulose (HPMC) functions as a multifunctional additive in water-based coatings — simultaneously acting as a thickener, film-forming agent, water-retention agent, and rheology modifier. Here's a deep look at its key performance contributions:
HPMC delivers precise pseudoplastic (shear-thinning) rheology in aqueous paint systems. At rest, high viscosity prevents sagging and settling of pigments. Under shear (brushing/rolling), viscosity drops sharply for smooth application — then recovers instantly, eliminating drips and runs on vertical surfaces.
On porous substrates like concrete, masonry, and gypsum boards, HPMC retards moisture loss from the wet coating film. This extended open time ensures complete coalescence of latex binders, preventing premature drying, cracking, and poor adhesion — especially critical in hot, arid climates.
The combination of HPMC's thixotropic behavior and its interaction with latex particles results in coatings that self-level during application while simultaneously resisting sagging. This delivers a smooth, professional finish even on overhead or vertical surfaces without additional anti-sag additives.
As the water phase evaporates, HPMC molecules orient at the coating-air interface, assisting in the formation of a cohesive, uniform film. This results in improved scrub resistance, better barrier properties against water and contaminants, and a visibly higher sheen and uniformity in the final coating surface.
HPMC acts as a steric stabilizer for TiO₂, calcium carbonate, and other particulate fillers in paint systems. This prevents flocculation, settling, and hard-cake formation during storage — extending shelf life to 12–24 months while maintaining uniform color distribution and hiding power throughout the paint's life.
HPMC exhibits a unique thermal gelation behavior — forming a gel above its cloud point temperature. In exterior coatings applied in intense sunlight, this thermoreversible behavior provides temporary structure that prevents drainage during hot application conditions, then reverts to liquid upon cooling for perfect film formation.
The global cellulose ether market for paints and coatings is undergoing rapid transformation driven by regulatory shifts, green construction, and performance innovation. Key trends shaping the HPMC landscape include:
The global water-based coatings market is projected to surpass USD 130 billion by 2030, with cellulose ether additives like HPMC playing a pivotal role in formulation optimization. Asia-Pacific leads growth, driven by China, India, and Southeast Asia's booming construction and real estate sectors.
Increasingly stringent VOC regulations in the EU (Directive 2004/42/EC), the US (EPA standards), and China's "GB 18582-2020" national standard are accelerating the shift from solvent-based to water-based coatings — directly driving demand for HPMC as the preferred thickener in low-VOC formulations.
LEED, BREEAM, and China's "Green Building Star" certifications increasingly specify low-emission interior coatings. HPMC-based formulations naturally meet these requirements due to HPMC's non-toxic, biodegradable nature — making it the thickener of choice for architects and specifiers targeting green certification.
Next-generation "smart coatings" incorporating photocatalytic, antimicrobial, and self-cleaning particles require exceptional dispersibility and suspension stability. HPMC's ability to uniformly suspend nano-TiO₂, silver nanoparticles, and specialty pigments makes it essential for advanced functional coating formulations.
From premium interior emulsion paints to high-performance exterior façade coatings and industrial protective systems, HPMC serves as a critical performance additive across the full coating application spectrum.
HPMC at 0.1–0.3% loading provides optimal viscosity (60,000–100,000 mPa·s at rest) for brush, roller, and spray application on interior walls. Its superior anti-drip and leveling properties ensure a uniform finish, while excellent water retention allows application over slightly damp plaster and concrete — a common requirement in new construction projects.
Exterior coatings face UV radiation, thermal cycling, rain, and freeze-thaw stress. HPMC grades with controlled thermal gelation provide sag resistance in high temperatures while maintaining application ease. JINJI's specially modified HPMC for exterior coatings demonstrates exceptional compatibility with elastomeric acrylic polymers, creating waterproof systems resistant to driving rain and carbonation.
High-build texture coatings (sand texture, stone effect, Venetian plaster) require high-viscosity HPMC grades (150,000–200,000 mPa·s) that maintain applied textures during drying without slumping. HPMC enables the incorporation of coarse aggregates, mica flakes, and glass beads at high loadings while maintaining sprayability through airless and hopper gun systems.
Water-based epoxy, polyurethane, and acrylic industrial coatings for steel structures, concrete floors, and marine environments demand precise rheology control. HPMC's compatibility with a wide pH range (3–11) and its stability in the presence of electrolytes (zinc, calcium salts) makes it indispensable in corrosion-inhibiting primer systems and anti-graffiti topcoat formulations.
Reflective roof coatings and liquid-applied waterproofing systems require both high elasticity and excellent film integrity. HPMC acts synergistically with styrene-acrylic and silicone-acrylic latex polymers, improving crack-bridging ability and elongation at break. JINJI's HPMC for waterproofing coatings maintains performance from -20°C to +80°C — suitable for demanding climatic zones from Scandinavia to the Middle East.
Deep-penetrating primers and bonding agents benefit from HPMC's ability to reduce surface tension while maintaining film continuity. Low-viscosity HPMC grades (5,000–15,000 mPa·s) enable deep penetration into porous concrete and masonry, enhancing adhesion for subsequent coating layers and reducing total system dry film thickness while maintaining performance.
