What is nurate skeleton urethane acrylate resin?
Nurate skeleton urethane acrylate resin is a material that combines high toughness and flexibility. In addition, it is characterized by excellent scratch resistance and resilience recovery, and is less likely to be scratched. It also features a yellowing-free type and excellent tensile strength.
By adding this nurate skeleton urethane acrylate resin to a coating agent having no elongation such as a high hardness hard coat agent, it is possible to impart flexibility corresponding to a flexible film.
Well, how does the characteristic properties of the nurate skeleton urethane acrylate resin develop?
The nurate skeleton consists of a trimerization reaction of isocyanates to form a six-membered ring called an isocyanurate ring. This framework has a significant impact on toughness and flexibility.
The toughness is developed by bridging the six-membered ring of the above nurate skeleton with the carbonate diol. At the same time, it is made to contain a large amount of urethane skeleton (polymerized) and tough carbonate material is used.
Similarly, the urethane skeleton is a nurate skeleton, and the urethane acrylate having this skeleton is the largest factor in flexibility.
Elastic recovery is realized by both cross-linking components (urethane backbone) and cross-linking between unsaturated groups (UV-curing components-polymerizing). Cross-linking of urethane components is developed from low-molecular-weight diols and isocyanates.
By adjusting these elements, you can change the balance between toughness, flexibility, and other properties and customize them for various applications. In addition, it is also possible to impart antistatic and antifouling properties to your requirements.
