2-Hydroxy-4'-(2-hydroxyethoxy)-2-methylpropiophenone CAS NO.106797-53-9

General

Chemacure PI-2959 is a highly efficient Free Radical Type I solid photoinitiator which is used to initiate the UV polymerization of chemically unsaturated prepolymers (e.g., acrylates) and unsaturated polyesters. It is especially recommended to use in low odor and water-borne systems. 

Chemical Structure

2-Hydroxy-1-[4-(2-hydroxyethoxy)phenyl]-2-methyl- 1-propanone

Molecular weight

: 224.25

Physical Properties

CAS No.

: 106797-53-9

Appearance

: White powder

Purity (%)

: ≥98.0

Melting Point (℃)

: 86-90

Absorption (nm)

: 274

Applications

Chemacure PI-2959 may be used in UV curable formulations on substrates paper, wood, metal and plastic materials. Its functional hydroxy group enhances its excellent compatibility in water-borne coating formulations. Chemacure PI-2959 demonstrates low volatility and low odor as a pure substance as well as in cured film, if compared with other commercially available photoinitiators.

The application of Chemacure PI-2959 reacting with functional resin backbone to form polymeric photoinitiators is may be of specific interests.

Chemacure PI-2959 recommended concentration: 2.0-5.0% 

Chemacure PI-2959 recommended applications:

Wood coatings

Coatings on Metals

Offset Inks

Overprint Varnishes

Flexo Inks

Since your specific applications and conditions of use are beyond

KBC’s control, you must determine the suitability of the product and

the suggestions mentioned herein for your specific applications.

UV Absorption Spectrum

Storage Conditions

Chemacure PI-2959 is sensitive to visible light and any exposure to sunlight should be avoided. Kept at low/ambient temperature and dry conditions. Avoid contacting with strong oxidants.

The product is stable for 2 years if stored in original, sealed containers under above-mentioned conditions.

Safety & Handling

Chemacure PI-2959 should be handled in accordance with good industrial practice. Detailed information is provided in the Material Safety Data Sheet (MSDS).

Packaging

20Kg carton

480 kg/ pallets
