Breaking Through Tile Adhesive Construction Challenges: Haichen New Materials Builds a Solid Foundation for Building Material Quality with HPMC Technology

With the upgrading and iteration of the architectural decoration industry, ceramic tiles have become the preferred decorative material for both residential and commercial spaces due to their advantages of aesthetic appeal, durability and easy maintenance. However, problems such as hollowing, peeling and cracking frequently occur during tile installation, which not only affect the aesthetics and safety of the space, but also hinder the high-quality development of the industry. As a leading enterprise in the domestic cellulose ether sector, Zhejiang Haichen New Materials Co., Ltd. has been deeply engaged in the industry for more than 30 years. With its core product Hydroxypropyl MEthyl Cellulose (HPMC) as the solution, the company fundamentally addresses the pain points in tile adhesive construction and injects strong impetus into the quality upgrading of the building materials industry.

The occurrence of tile adhesive construction problems often stems from multiple factors such as mismatches between material performance and construction scenarios, as well as non-standard operations. According to industry surveys, the three most common issues are hollowing and peeling, abnormal drying speed, and poor anti-sagging performance in vertical tiling. In extreme environments such as high temperature, low temperature and high humidity, ordinary tile adhesives are prone to excessive moisture loss or curing delay, resulting in insufficient bonding strength. When traditional tiling techniques are adopted, problems such as insufficient bonding area and improper base treatment further increase the risk of hollowing and peeling. Moreover, the popularity of large-format tiles has imposed more stringent requirements on the anti-sagging performance of tile adhesives.

As the core modifying component of cement-based tile adhesives, hydroxypropyl methyl cellulose ether (HPMC) directly determines the construction usability and bonding effect of tile adhesives. Made from natural cellulose via precise etherification reaction, it has become the key to addressing tile adhesive construction challenges by virtue of its excellent water retention, thickening and anti-sagging properties.

The water retention function of hydroxypropyl methyl cellulose ether (HPMC) forms a protective film in the tile adhesive system, effectively locking in moisture and preventing rapid moisture absorption by tiles or the substrate, which significantly enhances the bonding strength and durability of the tile adhesive. In high-temperature and dry environments, its water retention property can extend the open time of the tile adhesive, reserving ample space for construction workers to adjust tile positions and greatly reducing paving errors caused by tight operation time.

To address the anti-sagging challenge in vertical tiling, Haichen HPMC significantly enhances the viscosity and cohesion of tile adhesives by optimizing its molecular structure, forming a stable three-dimensional gel network structure. Even for large-format and high-density tiles, it can effectively prevent sliding and displacement after tiling, ensuring the flatness and stability of vertical construction. Meanwhile, it improves the troweling performance of tile adhesives, making the construction process smoother and more efficient.

In addressing the issue of abnormal drying speed, Haichen HPMC can meet the construction requirements of different temperature and humidity environments through precise regulation of product performance. In high-temperature conditions, it slows down the rate of moisture evaporation and prevents tile adhesives from drying and setting too quickly; in low-temperature conditions, it avoids cement curing delays that could impact construction schedules. Its excellent dispersibility ensures that tile adhesives are mixed uniformly without clumping, reducing performance fluctuations caused by improper material mixing.

As a participating drafting unit of the industry standards for cellulose ethers, Zhejiang Haichen New Materials Co., Ltd. has been focusing on the R&D, production and sales of non-ionic cellulose ethers since its establishment in 1990. Boasting advanced production processes and rigorous quality control, the company’s products have been exported to more than 80 countries and regions worldwide, including Germany, Russia and Japan, serving eight major sectors such as building materials and decorative coatings.
