In the field of building waterproofing, "rigidity" and "flexibility" have never been opposing choices but rather complementary solutions. High-performance waterproofing coatings represented by polyurethane (MPU), with their exceptional elasticity, seamless formation, and perfect integration with substrates, are becoming indispensable "flexible defenses" in modern waterproofing engineering. When they work in synergy with "rigid waterproofing" systems such as cementitious capillary crystalline materials, they form a perfect "rigid-flexible, complementary" waterproofing barrier. This article focuses on the unique advantages of polyurethane waterproofing coatings, exploring their irreplaceable role in complex details, bathrooms, basements, and other scenarios, and analyzes the development trends of new solvent-free and spray-applied coatings.
During the Lesser Fullness of Grain solar term, all things are abundant. On May 22, the senior and middle management team of Jiangxi Ganfeng Lithium Group Co., Ltd. (hereinafter referred to as Ganfeng Lithium) visited the Canlon Polymer Industrial Park to carry out a seminar and learning activity themed "Benchmarking against the best to promote development and intelligently leading change to start a new journey". The study tour was led by He Xingyao, Vice President of Ganfeng Lithium, with more than 40 participants including heads of various departments and centers. Vice Presidents Wang Pingping, Chen Hongjin, and Long Zhihong of Canlon, along with Zhao Dongliang, Director of the Human Resources Center, and other senior and middle-level leaders, warmly received the visitors.
Bengbu City in Anhui Province is a national comprehensive transportation hub, an industrial transfer and agglomeration area in northern Anhui, and a green agricultural product production, processing and supply base in the Yangtze River Delta. The famous Bengbu Port is the largest port on the Huai River. In recent years, driven by the "dual carbon" strategy, Bengbu Economic Development Zone is striving to build a new cluster area that undertakes industrial transfers from Shanghai, Jiangsu and Zhejiang, focusing on leading industries such as equipment manufacturing, new energy and new materials and modern logistics. This brings us to our protagonist today - Bengbu Lingang Assembly and Manufacturing Industrial Park.
Rock Protection System is a three-layer composite long-lasting waterproof protection system specially designed by Canlon for concrete roofs. Based on the design concept of layered material selection and gradient protection, it takes into account the adhesion of the base layer, the crack resistance of the structure and the weather resistance of the outdoors, and is perfectly adapted to the complex use environment of traditional concrete roofs such as sun exposure, rain, temperature difference and easy cracking of the base layer.
With the development of the drone industry and the low-altitude economy, more and more rooftops have become the simplest "landing pads," and even food delivery services can land here. Short video bloggers shoot viral aerial footage from high points in the city, and company employees can play tennis and have afternoon tea on the rooftop. Even the brand image of the entire company, and even the appearance of the city's landmark buildings, are repeatedly posted on short video platforms through aerial footage of rooftops. The roof is no longer just a "lid" for a building, but its brand-new "face". Let's talk about why high-quality buildings in the future will increasingly need a roof that is "sky-high and photogenic".
Against the backdrop of global climate change and increasing resource scarcity, "sustainable development" and "circular economy" have evolved from marginal concepts into core action frameworks across all industries. The construction industry, as a major carbon emitter, faces an urgent need for green transformation. Within this wave of transition, waterproofing materials are undergoing a profound green revolution—shifting from single-function products to full-lifecycle environmental value. Polymer waterproofing membranes represented by TPO and PVC, with their green attributes of recyclability, energy savings, and low VOC emissions, are becoming the technical foundation for low-carbon buildings and green certifications.
Recently, Canlon's SBS elastomeric modified bitumen waterproof membrane (root-barrier type) and MBBAC self-adhesive polymer modified bitumen waterproof membrane (root-barrier type) both passed the root penetration resistance test conducted by China Building Materials Testing & Certification Group Suzhou Co., Ltd. (CTC Suzhou), and obtained the "Root Penetration Resistance Performance Certificate" (CTCSZ2026019, CTCSZ2026020), continuously adding reliable new options to the field of green roof waterproofing.
Recently, the Ministry of Housing and Urban-Rural Development released the "Guidelines for the Construction of 'Good Houses' (Trial)," which sets out four core standards for high-quality housing construction in the new era: "safety and durability, health and comfort, green and low-carbon, and smart and convenient." Among them, waterproofing, moisture-proofing, leakage prevention, and damp-proofing are key bottom lines related to residential safety and quality. As a leading enterprise deeply rooted in the field of polymer waterproofing, Canlon closely aligns with the comprehensive requirements for "good housing" construction. It actively participates in the compilation of numerous national standards, national standard atlases, authoritative local standard atlases, and national reference atlases.
Commercial and industrial roofing system solutions have evolved from simple to sophisticated, and from single-function to all-encompassing. The core requirements they can meet are no longer limited to waterproofing, corrosion protection, fireproofing, moisture protection, and thermal insulation. Mature roofing systems can also meet high-level requirements for photovoltaic installation, wind uplift resistance, extreme cold resistance, and even acid rain and salt and alkali resistance. But have you ever considered that a good roofing system can offer more than just its performance in terms of intangible value? In this era that values "emotional value," can we homeowners expect more? Sure, my friend! Canlon will now share with you how a high-quality roofing system solution can enhance the overall value of a building!
