1、The basic performance and advantages of water-based UV coatings

1.1 The basic performance of water-based UV coatings
Waterborne UV coatings mainly include waterborne UV resins, photoinitiators, additives and colouring coatings. In all components, the water-based UV coating performance is the most influential water-based UV resin, water-based UV resin performance affects the strength of the coating surface curing film, corrosion resistance and curing sensitivity. Waterborne resins are also influenced by photoinitiators, which allow them to cure under the influence of light. Therefore, photoinitiators are also an important part of waterborne UV coatings, and the future development needs for photoinitiators are polymerisable and large molecules.

1.2 Advantages of waterborne UV coatings
1.2.1 Self-adjusting paint viscosity can be achieved without diluting monomers, eliminating toxicity and irritation in traditional coatings.
1.2.2 Rheological additives can be added appropriately to reduce the viscosity of the coating system, facilitating the coating process.
1.2.3 When coating materials such as clinker, water can be used as a thinner to improve the adhesion of the coating to the coating.
1.2.4 Improves the dust and scratch resistance of the coating before curing and improves the finish of the coating.
1.2.5 Cured film is ultra-thin.
1.2.6 Painting equipment is easy to clean.
1.2.7 Water-based UV coatings have good flame retardant properties.
1.2.8 Since low-molecular reactive diluents are not applicable, flexibility and hardness can be taken into account.

2、Water-based UV coatings in different areas of application

2.1 Wood in the wood surface application of water-based UV coatings in the varnish makes the surface wood grain of wood more expressive, thus increasing the beauty of the wood. This makes waterborne UV coatings more suitable for wood than traditional coatings due to their low toxicity, low irritation and fast curing properties, and the soft application of waterborne UV coatings is less likely to cause damage to the wood surface. Traditional coatings are usually affected by oxygen when used on wood surfaces, thus extending the curing time, but water-based UV coatings effectively solve this problem.

2.2 Paper water-based UV coatings can also be used as paper varnish, varnish is a liquid that covers the surface of printed materials, playing a waterproof role, but also to increase the wear resistance and gloss of the paper. At present, China's most commonly used paper varnish is water-based UV coating, the coating not only has a very high environmental performance, and in diluting the coating when using water instead of dilution solvent, effectively reducing the VOC content, as far as possible to reduce the harm caused by the coating to the human body, to facilitate the recycling of paper, therefore, the development prospects of water-based UV coating is extremely broad.

2.3 Other in the water-based UV coatings to add the right amount of functional alkenes, these functional alkenes will react with the active polymer, so that the curing film surface molecular rearrangement, so that the surface of the coating curing film will appear in certain patterns. The structure of the polymer varies, making the patterns appear differently, however, by controlling the structure of the polymer the type of pattern can be controlled, providing new ideas for the development of coatings, which can be applied in the direction of decoration and anti-counterfeiting. In addition, the technology can be applied to electronic materials and molecular design. In addition, the addition of a suitable amount of thermal insulation additive to the waterborne UV coating will produce a thermal insulation coating that is colourless and transparent, with good thermal insulation, good abrasion resistance, hardness, water resistance and corrosion resistance.
