UV/EB Curable Coatings
Utilised in formulations for protective and decorative coatings that cure rapidly under ultraviolet (UV) or electron beam (EB) radiation. It contributes to scratch resistance and gloss in wood, plastic, and metal coatings.
Printing Inks
Serves as a reactive diluent and crosslinker in UV/EB curable printing inks, offering good adhesion and pigment wetting. It aids in achieving fast cure speeds essential for high-throughput printing processes.
Adhesives
Incorporated into UV/EB curable adhesive formulations to provide strong bonding capabilities and excellent chemical resistance. It is suitable for applications requiring rapid setting and high performance.
Materials Science Research
Employed in research and development for novel polymer synthesis and material modification due to its crosslinking potential and acrylate functionality.
