UV coating, UV Spray painting, or ultraviolet coating, is a very glossy, shiny liquid coating applied to a printed paper or plastic surface and cured on a printing press or special machine using ultraviolet light. The coating hardens, or cures when it is exposed to the ultra-violet radiation.
Plastic is used in almost every industry, from aerospace innovation and 3D printing to electronics, medical equipment’s and product packaging. Many applications benefit from the advantages that coatings provide such as wear resistance, insulation, chemical resistance and improved performance – but plastic presents unique challenges such as,
- Heat Sensitive Plastics
- Low Energy Substrate
- Sensitivity to Solvents
Advantages of UV Coating for Plastics:
There are several reasons opting for custom UV coating service is the best decision for manufacturing:
- Scratch Resistance
- Dependable Chemical resistance
- Less Curing Time, which eventually results in better production efficiency
- Versatility in Colour and Finish Options
- Better Product performance in Harsh Environments
- Environment Friendly Solution
Electronics manufacturers use UV coatings to ensure durability and functionality of smaller plastic parts, while the automobile industry relies on UV Coatings on plastic components to have ideal appearance, scratch resistance and better functionality over the years.
All these major performance benefits of UV Coating typically also result in lower production costs compared to other coating options, making UV coating for plastic a cost-effective solution. When it comes to packaging, the excellent adhesion to plastics, visibility of product information on thermoplastic bags and other storage containers is vital for tracking purposes, quality assurance and customer satisfaction makes UV coating an ideal solution for it.
In addition to plastic polymers, UV coatings can be done on wooden surfaces and an endless amount of other industrial surfaces as stated below:
Plastics are of different types and each have their own unique characteristics and the proposed application plays a huge role in deciding the plastic material and coating requirement for to suit the application.
