With the popularization of prefabricated decoration and floor heating projects, the market has continuously raised requirements for the construction stability and finished product durability of gypsum-based and cement-based self-leveling mortars. To address common industry pain points such as bleeding and segregation, drying cracking, short open time, surface dusting and hollowing, Zhejiang Haishen New Materials Co., Ltd. has developed GinShiCel® Hydroxypropyl Methyl Cellulose Ether (HPMC) based on years of experience in cellulose ether R&D and production. As a core functional additive that improves the quality and construction efficiency of self-leveling mortars, it is widely applicable to residential, commercial and industrial floor construction scenarios.
As a national high-tech enterprise, GinShiCel® has long focused on the field of building material additives. Its self-developed and self-produced HPMC specially formulated for self-leveling mortars delivers outstanding water retention performance. Featuring a unique hydrophilic colloidal structure, the product forms a stable moisture-retaining network inside mortar to effectively trap free water. It prevents premature setting, surface dusting and uneven strength caused by rapid water absorption of substrates and air drying. It ensures complete hydration of gypsum and cement systems, greatly improving the compactness and bonding strength of floor layers, and eliminating potential quality

In terms of optimizing construction performance, Haishen HPMC features excellent thixotropic rheological properties tailored for self-leveling systems, perfectly balancing high fluidity and slurry stability. During paving construction, it enables the mortar to achieve superior self-leveling performance, which levels automatically by gravity and greatly boosts construction efficiency. After placement and shaping, it stabilizes the slurry rapidly, restrains aggregate settlement and water floating, eliminates defects such as bleeding, segregation, soft underlayer and hard crust, and effectively extends the open time to meet the requirements of large-area continuous floor construction.

Meanwhile, this product can effectively buffer the shrinkage stress generated during mortar hardening and reduce the cracking risk of thin-layer construction. It remarkably improves the wear resistance, impermeability and durability of floor screeds, and is precisely applicable to multiple scenarios including fast-set gypsum-based levelling layers and high-strength heavy-load cement-based floors. With the advantages of low dosage, high performance and environmental friendliness, HPMC from Zhejiang Haishen consistently drives the standardized, high-quality and eco-friendly upgrading of the floor building materials industry.
