Advantages and classification of photosensitive resins

UV curing resin, also known as photosensitive resin, is an oligomer that can undergo rapid physical and chemical changes in a short time after being irradiated by light, and then crosslink and cure. UV resin is a photosensitive resin with low relative molecular weight. It has reactive groups that can carry out UV, such as unsaturated double bond or epoxy group.

Photosensitive resin has the following advantages: when the resin is irradiated by light, the solidification speed of the resin will become very fast, and the resin will solidify rapidly, so the production efficiency of this resin will become very high. Due to the high energy utilization rate of resin, it can effectively save natural energy. The organic volatile matter in photosensitive resin is relatively small and will not cause great pollution to the environment. It is conducive to building an environment-friendly society and promoting the harmonious development of society, which is also the development direction of the country. This photosensitive resin material can also be applied to various substrates, such as paper and so on.

Classification of photosensitive resins: according to different types of solvents, photosensitive resins can be divided into solvent-based and water-based resins.

Solvent based photosensitive resin: solvent based resin is not hydrophilic, and can only be dissolved by organic solvents, not water. Commonly used solvent based photosensitive resins include UV polyether propylene ester and other materials.

Waterborne photosensitive resin: waterborne resin is hydrophilic and can be decomposed or dispersed in water. The water-based photosensitive resin can be dissolved in water, and the molecule contains a certain number of hydrophilic groups and a certain number of unsaturated groups. These two groups promote the hydrophilicity of the water-based photosensitive resin, mainly including water-based polyurethane acrylate and other materials.
