Advantages of Polycarbonate Acrylate Oligomers in UV Systems
1. Low Viscosity, High-Solids Friendly
Lower viscosity than polyurethane or polyester acrylates
Enables high-solid or solvent-free formulations
Reduces the need for reactive diluents
👉 improves film properties and lowers shrinkage and odor
2. Fast UV Curing and High Conversion
Acrylate double bonds provide high reactivity
Flexible carbonate backbone enhances radical mobility
👉 fast surface and through-cure, even in thick films or LED-UV systems
3. Low Shrinkage and Excellent Adhesion
Carbonate linkages have high cohesive energy
Lower polymerization stress compared with multifunctional monomers
👉 excellent adhesion to glass, metals, PC, PET, PMMA
👉 reduced cracking, curling, and delamination
4. Excellent Balance of Hardness and Flexibility
Harder than polyether acrylates
More flexible than conventional polyester acrylates
This makes PC acrylates ideal for “hard-but-not-brittle” UV coatings.
5. Superior Weathering and Non-Yellowing
Carbonate groups are more stable than ester groups
Can be designed as fully aliphatic systems
excellent UV resistance and low yellowing, suitable for clear and white coatings
6. High Transparency and Optical Performance
Low haze and good refractive index stability
Minimal crystallization
👉 widely used in optical coatings, display films, and electronic protection layers
7. Excellent Compatibility and Formulation Flexibility
Good compatibility with common acrylate monomers and oligomers
Can function as:
main resin
toughness modifier
reactive diluent
8. Particularly Suitable for LED-UV Systems
Efficient curing under low-energy light sources
Allows reduced photoinitiator levels
lower yellowing and improved optical clarity
Typical UV Applications
UV-curable clear coats for plastics (PC, PET, PMMA)
Optical and display coatings
UV adhesives with low shrinkage
Electronic and 3C product protection coatings
Automotive interior and exterior UV coatings
