| Résumé : |
New photosensitive resins based on renewable unsaturated oils have the potential to as least match most benchmark acrylate resins. The resins can be cured under mild conditions with a patented system. Coatings, inks, paints, composites, and 3D printing could well benefit. |
| Note de contenu : |
- A need for for saver alternatives
- Metal-free
- And bio-based
- Experimental
- Fast-curing photosensitive alkyds
- Photochemical beats thermal
- Photoinitiating ability under different conditions
- Faster composites from impregnated fibres
- Dark curing
- 3D polymerisation with a DLP 3D printer
- Better solvent resistance for coatings
- Uses in paints/inks
