● The degree of localization of R&D and production continues to increase
● Covers four major fields: rail transit, infrastructure, printing and packaging, and industrial painting.
● Cooperated with professors from Tongji University and Global Food Information Network to release a white paper on sustainable packaging for food and beverages
From November 14th to 17th, Covestro’s “Creating and Sustaining the Future” series of activities were held concurrently with the China International Coatings Exhibition. As the opening of the series of events, Covestro released five major low-carbon polyurethane coating solutions, covering the fields of rail transit, infrastructure, printing and packaging, and industrial coating. Among them, four solutions were developed by Covestro Asia Pacific Innovation Center in Shanghai and will also be produced in China in the future. From the breadth of industry coverage to the speed of market response, this release demonstrates Covestro’s determination to fully empower the development of China’s coatings and adhesives market.
“China is one of the largest markets in the world for Covestro and one of the largest polyurethane markets in the world. Covestro will continue to deeply explore the Chinese market and empower the development of industry customers. For example, the recently completed Shanghai water-based polyurethane dispersion (PUD) new The factory will protect the growing demand for environmentally friendly coatings in the Asia-Pacific, especially the Chinese market.”
Anand Khot, Senior Vice President of Covestro’s Coatings and Adhesives Division Asia Pacific, shared at the new product launch conference held at the Asia Pacific Innovation Center.
Continuing Covestro’s idea of low-carbon exhibitions, this series of “Creating and Sustaining the Future” activities also includes online seminars, online exhibition halls and other forms, aiming to provide a flexible, convenient and efficient communication platform for industry colleagues.
Start with innovation and expand product portfolio horizontally
Covestro focuses on customer needs and continuously expands its product portfolio to meet the industry’s high-quality development demands such as reducing carbon emissions and improving quality and efficiency. New products released this time include:
● In order to meet the needs of low-carbon, environmentally friendly and efficient coating in the rail transit industry, Covestro has locally developed an innovative curing agent, Desmodur® N, which can be used for coating metal parts in rail transit.
31500. This product is suitable for a two-component no-bake high-solids system, which can realize rapid curing coating on the bottom surface. It is expected to save about 25% of energy consumption for the terminal production workshop every year, and reduce the comprehensive annual carbon dioxide emissions by about 24,000 tons[1 ]. It can also be used in automatic painting and polishing processes, which can effectively improve the working environment while improving construction efficiency.
● Desmodur® ultra E
30800 is an environmentally friendly solvent-free isocyanate curing agent based on HDI. It is especially suitable for polyaspartate coating systems and can be widely used in flooring, caulking agents, anti-corrosion coatings and other fields. This product has ultra-low free monomer content, effectively ensuring industrial hygiene and safety; its low viscosity does not require the use of solvents for dilution, and can balance a longer operating period with faster drying speed; it also has excellent water resistance and durability Sex, hardness and softness.
● In order to cope with the impact of severe weather or environmental conditions on industrial painting, Covestro has locally developed an upgraded water-based acrylic emulsion, NeoCryl® XK
824. This product has excellent early water resistance, which can effectively prevent damage to the undried paint film caused by humid environments and ensure that the surface of the workpiece is intact during the painting and drying process. The rapid hardness establishment can meet the process needs of rapid stacking of workpieces off the production line and improve production efficiency. In addition, its excellent performance in salt spray resistance will further enhance the performance of industrial light anti-corrosion coatings and can be applied to primers, topcoats and bottom-in-one paints for metal substrates.
●
Driven by the trend of sustainable development in the packaging field, the application scenarios of paper-based packaging materials continue to expand. Covestro has developed a new water-based acrylic emulsion, NeoCryl® A, specifically for barrier coatings on food-contact paper packaging.
2085. This product has excellent water resistance and grease resistance, which can effectively protect the taste and quality of food. Because it does not contain fluoride, it is an environmentally friendly alternative to additives such as PFAS (perfluoroalkyl and polyfluoroalkyl substances), ensuring consumer health and safety. Using NeoCryl®
The barrier coating solution of A 2085 can replace traditional polyethylene (PE) plastic coating for paper packaging, helping to realize paper recycling and reuse. After testing, the pulp recyclability rate is greater than 90% [2].
● Alternative raw materials are an important part of realizing a circular economy. Discovery® CQ, a partially bio-based water-based acrylic emulsion launched by Covestro
The bio-based content of 6010 is about 37%. When used in barrier coatings, it can achieve the same barrier performance as traditional fossil-based products (based on the waterproof performance COBB test and anti-grease performance Kit test). This product has extremely low water vapor transmission rate (MVTR), which can effectively protect food freshness and extend shelf life. Discovery®
CQ 6010 can also replace multi-layer paper food packaging materials such as polyethylene (PE) lamination technology. After testing, the pulp recyclability rate is greater than 90% [3], helping to realize the recycling and reuse of food paper packaging.
Persistently develop service capabilities vertically
Horizontally expand product portfolio to cater to the innovation and development needs of multiple industries. Vertically develop service capabilities to meet the multi-dimensional needs of a single industry. To this end, Covestro also teamed up with the United Nations Environment Program-Tongji University School of Environment and Sustainable Development Professor Du Huanzheng and the National�Food Information Network jointly released the white paper “Sustainable Packaging Innovation Trends – How Food and Beverage Companies Achieve “Comprehensive Cycle”” to discuss how to promote the development of packaging technology in a recyclable and sustainable direction, focusing on recyclable paper-based materials and single-material flexible packaging. , bio-based inks and adhesives and other fields.
