1. Description
NBOA is a mono-functional cycloaliphatic acrylate monomer containing a bridged-ring structure.
2. Applications
- Reduces viscosity in acrylic resin synthesis
- Serves as a low-odour reactive diluent in UV-curable coatings, improving the application environment
- Gives coatings good distinctness of image, gloss and weather resistance
