Chemial Name: 2-Hydroxy-4′-(2-hydroxyethoxy)-2-methylpropiophenone
Synonym:DAROCUR 2959; IRGACURE 2959;Speedcure 2959;Omnirad 659
Molecular Formula: C12H16O4
SINOCURE® 2959 is a high-efficiency non-yellowing UV photoinitiator, used to initiate UV polymerization of unsaturated prepolymerization systems, especially suitable for low odor, low volatility, low yellowing, water-based acrylate and unsaturated polyester resins.
|Appearance||White crystalline powder|
|Loss On Drying||≤ 0.5%|
SINOCURE® 2959 has been tested for use in UV-curable formulations for wood, metal, plastic and paper surfaces. The hydroxyl functional group in the molecule increases the solubility of SINOCURE® 2959 in waterborne coating formulations.
SINOCURE®2959 has lower volatility and odor compared to SINOCURE® 1173. Importantly, the active hydroxyl groups of SINOCURE® 2959 can be easily grafted onto polymer molecules, making its processing more convenient. Due to its unique properties,SINOCURE® 2959 is especially recommended for UV formulations that require high temperature and air flow to evaporate moisture before curing.
