With the arrival of the Chinese New Year, JINJI CHEMICAL would like to send our heartfelt thanks to all customers, distributors, and partners for your support throughout the past year. JINJI CHEMICAL will be closed for the Chinese New Year holiday from February 13 to February 23, 2026, and normal business operations will resume on February 24, 2026. [...]

Hydroxypropyl Methylcellulose (HPMC) plays a critical role in modern dry mix mortar formulations. Although it is typically used at low dosages, HPMC in dry mix mortar directly affects water retention, workability, open time, sag resistance, and overall application performance. When used correctly, it enhances both on-site efficiency [...]

In global construction and coating markets, climate is often one of the most underestimated factors influencing the real performance of cellulose ethers. In practice, many manufacturers discover that a cellulose grade performing perfectly in one country may lead to fast drying, sagging, reduced workability, or surface defects after being exported to another [...]

Choosing the right HPMC cellulose supplier is one of the most critical decisions for manufacturers of tile adhesive, wall putty, coatings, detergents, and other construction or chemical products. Hydroxypropyl Methylcellulose (HPMC) may represent only a small percentage of your formulation, but its performance directly affects water retention, workability, surface appearance, and long-term customer [...]

In the global coatings industry, surface quality is a decisive factor that directly affects product performance, customer satisfaction, and brand reputation. Across international markets such as South America, the Middle East, Russia, Southeast Asia, and Africa, coating manufacturers face constant challenges related to climate, application methods, and raw material [...]

In the building materials industry, tile adhesives play a critical role in ensuring durable and aesthetically pleasing surfaces. One of the key challenges in tile installation is managing the "open time"—the period during which the adhesive remains workable after application to a substrate before tiles are placed. A short open time can lead to poor bonding, wasted materials, and increased labor costs. To address this, additives are incorporated into adhesive formulations to extend open [...]

In the competitive world of architectural and industrial coatings, achieving a flawless, mirror-like high-gloss finish with water-based technology represents one of the industry's most sought-after goals. This quest is driven by stringent environmental regulations, growing consumer demand for sustainable products, and an unwavering expectation of premium performance historically associated with solvent-based systems. The formulation of high-gloss water-based paints is a complex balancing [...]

The construction industry's shift towards energy-efficient building solutions has propelled lightweight Expanded Polystyrene (EPS) panel systems to the forefront for cladding, insulation, and partition walls. The efficacy of these systems is intrinsically linked to the performance of the specialized mortars used for bonding and coating. These mortars must adhere to a low-density, hydrophobic substrate while remaining flexible, crack-resistant, and workable. The critical component enabling this suite of properties is Redispersible Polymer Powder (RDP).

In the construction and building materials industry, exterior wall putty plays a critical role in providing a smooth, durable, and aesthetically pleasing finish to building façades. However, its performance is heavily influenced by environmental conditions, particularly in regions characterized by high humidity and frequent rainfall. In humid climates, traditional putty formulations often face challenges [...]
