Polyurethane coating is called “liquid rubber”
, is internationally recognized as one of the materials with the best waterproofing effect. Since its birth, it has been supported by national industrial policies and favored by the market. Among them, anti-sag polyurethane achieves better waterproofing effects due to its excellent adhesion in facade construction scenarios.
“Anti-sag polyurethane waterproof coating” will come into effect on September 1st
In order to better promote the technological progress of anti-sag polyurethane waterproof coatings, effectively solve the problem of building waterproofing, reduce the leakage rate of buildings, and promote the development of my country’s building waterproofing industry, Karen Co., Ltd. and China National Building Materials Suzhou Waterproofing Research Institute Co., Ltd. The CECS standard for “Anti-sag Polyurethane Waterproof Coating” co-drafted and edited by the editor-in-chief was reviewed by the Association’s Professional Committee on Waterproof Protection and Restoration. It is now approved for release and will be officially implemented from September 1, 2023.
1. Technical background
In recent years, with the continuous development and improvement of polyurethane waterproof coating technology, its proportion in waterproof coatings is increasing, and its usage is also increasing. Currently, architectural waterproof coatings maintain a steady growth momentum every year, with an annual growth rate of About 10%, of which polyurethane waterproof coatings account for 30.8% of the entire waterproof coating market, and are mainly used in first-level waterproof design projects.
Since the formulation of “Anti-sag Polyurethane Waterproof Coating” was approved as a project, Karen Co., Ltd. has actively leveraged its pioneering advantages in the research and development and application practice of anti-sag polyurethane technology and invited the preparation team to Karen Polymer Industrial Park many times. Conduct working meetings, fully discuss the discussion draft, and conduct in-depth exchanges on product verification work.
