The JS waterproof coating industry is moving towards a new stage of high-quality development.

With the in-depth advancement of the national "dual carbon" strategy and the continuous improvement of building quality requirements, the polymer cement (JS) waterproof coating industry, which is a core material in the building waterproofing field, is undergoing an industrial upgrade dominated by "high toughness", "environmental friendliness" and "system solutions". Industry experts point out that the market potential of JS coatings with outstanding comprehensive performance is being further stimulated, but at the same time, it also puts forward higher requirements for the technological research and development and comprehensive service capabilities of enterprises.

Technological iteration: From "Flexibility" to "high toughness", addressing the challenge of building structure deformation

The traditional JS waterproof coating mainly meets the basic requirements of flexibility and impermeability. However, with the large-scale construction of modern projects such as prefabricated buildings and underground pipe galleries, the shrinkage, vibration and slight displacement of base concrete have become more common, which puts forward almost strict requirements for the elastic recovery rate, elongation at break and dynamic adhesion to the base surface of waterproof coatings.

"The core competitiveness of the new generation of JS coatings lies in 'toughness' rather than merely 'flexibility'," Zhang Wei, the secretary-general of the China Building Waterproofing Association, stated at a recent industry technical seminar that "High-toughness JS coatings can better absorb and disperse stress. Even when cracks of 2-3 millimeters occur in the structure, the coating film remains intact, effectively avoiding the failure of the waterproof layer caused by the cracking of the base layer. This significantly enhances the reliability and durability of building waterproofing projects." "

Green and environmental protection: From "Limit of Hazardous Substances" to "Environmentally friendly throughout the entire life cycle"

The tightening of environmental protection regulations and the awakening of consumers' health awareness are driving JS waterproof coatings to develop in a cleaner and safer direction. Industry standards have expanded from merely restricting VOCs (volatile organic compounds) to a complete ban on harmful additives such as nonylphenol polyoxyethylene ethers (APEO). Meanwhile, the adoption of water-based emulsions with low environmental load and the development of powder components with low dust and easy recyclability have also become the research and development priorities of Enterprise benchmark.

"Greening is no longer an option but the bottom line for survival and development," pointed out Wang Lifeng, the technical director of a well-known building materials group. "We are committed to building a complete chain from green raw materials, green production to green construction." For instance, our new product adopts bio-based modified emulsion, which significantly reduces the carbon footprint of the product while ensuring its performance.

Application Deepening: From "Single Material" to "Integrated System Solution

The market is gradually discarding the notion of treating JS coating as a single waterproof material and instead emphasizing its core value as a "system solution". This includes compatibility with different base layers (such as concrete, masonry, and metal plates), composite application schemes with other waterproofing materials (such as rolls and sealants), as well as reinforcement treatment methods for special parts (such as pipe roots and corners).

"Future competition will be a competition of system solutions," said Li Jing, a senior industry analyst. "Leading enterprises not only offer high-quality coatings but also provide 'one-stop' services including base treatment solutions, standardized construction tools, professional construction training and long-term quality assurance." This can ensure the waterproofing effect to the greatest extent and reduce the engineering risks.

Future Outlook: Standardized construction and intelligent supervision

Despite the continuous improvement of material performance, the uncontrollability of the construction process remains a pain point in the industry. In the future, promoting standardized construction techniques, training professional industrial workers, and using Internet of Things (iot) technology to digitally supervise key processes such as paint mixing and coating thickness will become the key to enhancing the overall level of the industry. Meanwhile, the intelligent JS coating with self-healing function has also entered the laboratory stage, indicating the unlimited possibilities of the industry's future.

The JS waterproof coating industry is building a more solid defense line for building safety under the multi-dimensional drive of quality, environmental protection and service.
