Key Features
- Outstanding weather resistance and non-yellowing performance: The aliphatic molecular structure endows the product with strong resistance to outdoor environmental factors such as ultraviolet radiation and temperature changes, and it is not prone to yellowing after long-term use, effectively maintaining the original appearance of the coated substrates.
- Excellent mechanical properties: It has an ideal balance of high hardness and good toughness, making the formed coating film able to resist external scratches and impacts, and at the same time adapt to a certain degree of deformation of the substrate without cracking, ensuring the integrity of the coating film.
- Superior chemical and water resistance: The coating film formed by this product has strong resistance to water erosion and various chemical substances, and is not easy to be damaged by water immersion or chemical contact, thus extending the service life of the coated substrates.
- Excellent application process performance: It has very good fluidity, which can form a uniform and smooth coating film on the surface of substrates during construction, and it is not easy to produce foam, reducing the occurrence of coating defects such as pinholes and bubbles, and improving the construction efficiency and finished product quality.
- Solvent-free environmental protection feature: The solvent-free formulation design reduces the emission of volatile organic compounds (VOCs) during production and construction, in line with the environmental protection standards of the coating industry and reducing the impact on the environment and human health.

Applications
- Package film OPV coatings: The product’s outstanding non-yellowing performance ensures that the package film maintains a clear, bright and attractive appearance for a long time, avoiding discoloration that affects the visual presentation of packaged products. Its excellent water and chemical resistance can effectively protect the package film from erosion by the packaged contents and external environmental factors, ensuring the barrier performance of the film. In addition, the good toughness of the product matches the flexible characteristics of package films, making the coating film not easy to crack or peel during the processing, transportation and use of the film, and maintaining the complete protective effect of the coating.
- Wood coatings: It is widely applicable to the coating of various wood products including solid wood furniture, wood doors and windows, wood decorative panels and outdoor wood materials. Its non-yellowing performance and weather resistance can prevent the wood surface coating from discoloring, fading and aging when exposed to light or used in outdoor environments for a long time, effectively retaining the natural texture and beautiful appearance of wood. The excellent hardness and scratch resistance of the product can protect the wood surface from daily wear and tear, while its good water and chemical resistance can prevent wood from being eroded by water, cleaning agents and other daily chemicals, thus greatly extending the service life of wood products.
- Plastic substrate coatings: It is suitable for the surface coating of various plastic products with different properties and application scenarios, such as plastic daily necessities, plastic hardware accessories and industrial plastic parts. Plastic substrates usually have the characteristic of low surface energy, and the good fluidity of this product ensures excellent wetting and leveling performance on the plastic surface, forming a uniform and compact coating film. Its balanced hardness and toughness can adapt to the certain flexibility of plastic substrates, avoiding coating film cracking caused by plastic deformation during use. Meanwhile, the excellent water and chemical resistance also makes plastic products more resistant to external environmental erosion, improving the durability and added value of plastic products.
Benefits
- For manufacturers: The product has stable technical parameters and excellent process performance, with good fluidity and anti-foaming property during construction, which can reduce the occurrence of coating defects, improve the qualified rate of finished coating products and production efficiency. Its solvent-free formulation conforms to environmental protection policies, helping manufacturers reduce environmental treatment costs and meet the green production requirements of the industry. At the same time, the product has a clear and standardized storage condition, which is convenient for manufacturers to manage inventory and reduce the loss caused by product deterioration.
- For application constructors: The good fluidity of the product makes the construction operation more convenient, and it is not easy to foam during the coating process, reducing the time and labor cost of post-processing of coating defects, and improving the construction speed and construction quality. The waterborne and solvent-free characteristics also reduce the stimulation of organic solvents to the human body during construction, improving the construction environment and protecting the health of constructors.
- For end users: The coatings prepared from this product can provide long-term protection and decoration for wood and plastic products as well as package films. The non-yellowing and weather resistance keep the appearance of the products bright and new for a long time, and the excellent water, chemical and wear resistance extends the service life of the products, reducing the cost of replacement and maintenance. For package film users, the high-performance coating film can better protect the packaged contents, ensuring the safety and integrity of the products during transportation and storage.
- For the environment: The solvent-free waterborne formulation greatly reduces the VOCs emission in the whole process of coating production, construction and use, reducing air pollution, and conforming to the sustainable development concept of the coating industry, which is conducive to the ecological environmental protection.
