Empowering the Upgrade of the Coatings Industry! Zhejiang Haishen's HPMC Unlocks a New Level of Coating Performance

As a participant in formulating China's national standards for the Cellulose Ether industry and a high-tech enterprise, GinShiCel® Hydroxypropyl Methyl Cellulose (HPMC) is produced via etherification from natural polymeric cellulose. It appears as an odorless, tasteless and non-toxic white powder that swells in cold water to form a clear colloidal solution. Boasting multiple outstanding properties including thickening, dispersing, emulsifying, water retention and film-forming, it is widely applied in eight major fields such as decorative coatings, serving more than 80 countries and regions worldwide.

In coating formulations, hydroxypropyl Methyl Cellulose (HPMC) acts as a key functional additive and plays a core role as a "performance regulator". Its multi-faceted effects run through the entire life cycle of coatings from production and construction to application, thoroughly addressing the industry pain points of traditional coatings such as easy sagging, sedimentation, cracking and poor adhesion, and driving the upgrading of coating products towards high efficiency, high quality and environmental protection.

Rheological modification and thickening lay a solid foundation for construction ease. Through the entanglement and hydration of molecular chains, HPMC forms a three-dimensional network structure, which can precisely regulate coating viscosity and effectively improve the anti-sagging performance of coatings, ensuring no dripping or running during vertical surface construction. Meanwhile, it endows coatings with excellent thixotropy—viscosity decreases under shear force during construction for easy brushing, rolling or spraying, and quickly recovers after construction to avoid brush and roller marks, greatly enhancing construction efficiency and finish quality.

Water Retention & Moisture Locking + Extended Open Time, Eliminating Construction Risks. During coating application, excessive rapid water evaporation tends to cause cracking and sanding of the coating film, a problem that is particularly pronounced in high-temperature and dry environments. GinShiCel® HPMC boasts superior water retention performance with a water retention rate of over 85% in cement-based coatings. It effectively slows down water evaporation, extends the open time of coatings, provides sufficient time for film formation, and prevents coating defects caused by rapid water loss.

Dispersing Stability & Anti-Sedimentation, Ensuring Stable Storage and Application of Coatings. Solid particles such as pigments and fillers in coatings tend to aggregate and settle during storage, causing coating delamination and uneven color, which impairs application effects. Relying on its excellent steric hindrance effect, HPMC can effectively prevent the aggregation of pigment particles and disperse pigments and fillers uniformly in the coating system.

Film-Forming Enhancement & Adhesion Boost, Prolonging the Service Life of Coating Films. GinShiCel® HPMC features excellent film-forming properties. During the coating drying process, its molecular chains interweave with each other to form a dense and flexible film, which not only tightly bonds components such as pigments and fillers in the coating to improve the integrity and mechanical strength of the coating film, but also enhances the adhesion between the coating and substrates (e.g., cement, wood, wall surfaces). It effectively reduces coating film problems such as peeling, flaking and cracking, and at the same time endows the coating film with good water resistance, weather resistance and chemical corrosion resistance, making the coating suitable for both interior decoration and application requirements in complex outdoor environments.

Notably, GinShiCel® HPMC offers a comprehensive range of functions alongside outstanding environmental benefits and high compatibility. Non-toxic and odorless, this product is eco-friendly and aligns with the current "low-carbon and environmental protection" development trend of the coatings industry. It is widely compatible with various coating systems including water-based latex paints, waterproof coatings, tile adhesives and dry powder ceramic coatings. With a pH value ranging from 5 to 9, it boasts excellent compatibility with all types of emulsions, solvents and additives. Its addition level can be flexibly adjusted according to the specific requirements of coating products without the need for major formula modifications, providing convenience for coating enterprises to reduce their R&D and production costs.
