Esacure ONE by IGM Resins is a difunctional oligomeric alpha hydroxy ketone. It is a type I photoinitiator. Provides through and surface cure. Formula (1) was prepared using both Esacure M (A) and Esacure ONE (B). The results of the tests performed are reported in figures 1 & 2. Curing was. ONE offers very low odor levels and low migration but suffers from low solubility. A liquid version, Esacure ONE 75, is a 75% solution of ONE in 25% ethozylated.

The solution thus cools down and solidifies. LU Free format text: LV Free format text: This solution is not suitable for aqueous systems. Further examples of unsaturated oligomers are unsaturated polyester resins, which are usually prepared from maleic acid, phthalic acid and one or more diols and have molecular weights of from about to Higher concentrations of the photoinitiator are not disclosed. LI Free format text: As additional photoinitiators oligomeric compounds such as for example oligomeric alpha hydroxyl ketones e.

Said blend should be suitable for aqueous based and solvent based radiation curable systems.

ESACURE ONE

This product is a new high reactive difunctional photoinitiator particularly suitable for clear systems. Again the curing results demonstrate that the liquid photoinitiator blends provide useful good curing performance despite the dilution with blend components. Also high energy input is required to prepare the product form dispersing process.

An example for a castor oil ethoxylates is one marked under the trademark Hedipin. The following water-based formulation was prepared WB-Formulation 1: The formulation was placed into a glass bottle and photoinitiator was added during stirring with toothed disk at rpm. For reference, a photoinitiator free sample of esacurs formulations was treated in the same way.

The term also refers to compounds containing one or more acetylenic groups, which can be connected through the residue of a linking group to one or two oligomeric or polymeric chains of alkylene oxide residues. They may be of low monomeric or high oligomeric molecular mass.

Grain enhancement with surfactants in water-based uv-radiation curable polyurethane dispersions. Examples of alkoxylates of alkine-alcohols or alkine-diols are product sold under the Trademarks: The C 1 -C 22 alkyl group in the above mentioned alkoxylates is linear or branched, saturated or unsaturated and preferably C 6 -C It has now been found that mixing a photoinitiator of the radical type with a liquid surface active agent, and optionally with an organic diluent leads to a homogenous liquid blend with a high content of photoinitiator and which is stable at room temperature.

Therefore liquid photoinitiators are preferred for producing of UV-curable paints. After cooling, the pendulum hardness according to Koenig was measured. Examples of alcohols are isodecanol, CC15 oxoalcohols, propylene glycol, dipropylene glycol, tripropylene glycol, oligoethylene glycols like diethylene glycol, triethylene glycol, tetraethylene glycol and glycerin.

It is also used for powder coatings, food packaging, and onf lacquers for wood, plastic, paper, metal, and optical fibers. Interesting also are resins which are modified with silicon or fluor, e.

Solubilizing solid photoinitiators into the coating formulation may require excess or additional diluents that could adversely affect the properties of the coating or may be undesirable from environmental aspects. Lamberti requires water to obtain a heterogeneous product form at room temperature.

The unsaturated compounds may include one or more olefinic double bonds. Applications Products Highlights Technical support. The alkoxylated surface active agent is responsible for the emulsifying properties and for providing compatibility of the resulting photoinitiator additive concentrate towards aqueous and non-aqueous formulations like paint or ink formulations. NO Free format text: At first a homogeneous solution is prepared by adding the photoinitiator at elevated temperatures to the surfactant.

It has now been found that mixing a photoinitiator of the radical type with a liquid surface active agent, and optionally with an organic diluent leads to a homogenous liquid blend with a onee content of photoinitiator and which is stable at room temperature.

A dispersion solid particles of the photoinitiator is obtained.
