| Résumé : |
This paper confirms that exceptional reactivity of dendritic polymers in UV-curable coatings can be obtained. The dendritic polyester acrylate fully cures without any photo initiator and at low lamp intensity. Obtained film further had extraordinary chemical resistance and scratch resistance. The high functionality at any given molecular weight of dendritic polymers allows for exceptional cure speed. |
| Note de contenu : |
- Multi-functional core with branched aliphatic polyester structures
- Polyester type brings advan tageous coating properties
- Reactivity of dentitric polyester acrylate in UV-curable coatings is high
- Tertiary amines with abstractable a-hydrogens are known for reducing air inhibition and promoting cure speed
- The particular amine chosen: butyl aminoethanol
- Higher cure speed with 0.1% Benzophenone |
