Application areas
Chemical structure: PUA is a copolymer composed of polyurethane and acrylate groups. Polyurethane groups typically come from the reaction of isocyanates with polyols, while acrylate groups are typically used in the light-curing process.
Light-curing properties: PUA is typically used in light-curing applications, meaning it can be quickly cured by exposure to ultraviolet (UV) or visible light. This property makes it very useful in areas such as printing, coating and 3D printing, as it allows rapid production and precise curing.
Customizability: PUA can be customized to achieve a wide range of physical and chemical properties by adjusting the raw materials and reaction conditions in the formulation. This makes it suitable for a variety of applications, including varying adhesion, hardness, flexibility and optical property requirements.
Application fields: PUA is used in the printing industry to make light-curing inks, which can be used for labels, packaging and printed circuit boards. It is also widely used in coatings, adhesives and 3D printing materials. PUA also has important applications in medical devices, electronic equipment, aerospace and automotive industries.
Environmental considerations: In some cases, PUA can be designed as a low-volatile organic compound (VOC) material to reduce environmental impact. This is especially important in coating and printing applications.
