Photoinitiator KIP 160
2-Hydroxy-1-[4-[4-(2-hydroxy-2-methylpropanoyl)benzyl]phenyl]-2-methylpropan-1-one
Dimeric α-hydroxy ketone — Type I performance with minimal migration and odor.
Product Description
KIP 160 is a bis-acylphosphine-free, dimeric α-hydroxy ketone: two 1173-type chromophores joined through a methylene bridge. The doubled molecular weight cuts volatility, odor and migration dramatically while preserving the fast cure typical of α-hydroxy ketones.
It is a preferred Type I initiator for food-packaging inks and low-odor coatings, and its two chromophores raise efficiency so that typical loadings drop to 1–3 wt%.
Key Features
- Dimeric structure minimizes migration and odor
- Fast Type I cure at reduced loadings
- Excellent for food-contact compliance programs
- Low volatility — clean high-speed processing
Applications
- UV inks for food packaging
- Low-odor overprint varnishes
- Clear coatings for paper and board
- UV adhesives for sensitive substrates
- Electronics conformal coatings
