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.

This is in contrast to the reference Irgacurewhich due to the incompatibility does not give a useful waterborne UV-paint.
Optionally the blend may contain water. The optional organic diluent is chosen from the esacrue consisting of high boiling inert liquids based on ester and or ether compounds like: IGM offers a broad portfolio of free radical photoinitiator products ranging from the alpha hydroxy ketone OmniradOmnirad 73alpha-amino ketone Omnirad and Omnirad and acylphosphine oxide Omnirad TPO family to benzophenones.

We’re sorry, but the industry you have selected is not currently available in your chosen language. Also preferred are non-ionic surfactants derived from ethoxylated esters of fatty acids with glycerine or sorbitan, such as polyoxyethylene glycerine monostearate, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monopalmitate, polyoxyethylene sorbitan-monostearate, polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan tristearate, polyoxyethylene sorbitan trioleate.
The photoinitiator samples were tested in esacur different water-based clear coat formulations.

The product form is a clear yellowish liquid. PT Free format text: With oje widest variety of photoinitiators that upon exposure to UV light decomposes into free radicals that initiate a polymerization between diluting acrylates and acrylated oligomers, ezacure free radical system is adopted for most applications. RO Free format text: The problem underlying the present invention is to provide a liquid photoinitiator blend which remains liquid and homogeneous i.
The suspension obtained is then treated in a colloid mill to obtain particles in the range of 0.
Preferably, the pure surfactant is a liquid at room temperature. LI Free format text: REF Ref document number: TRGR Ref country code: Other examples are acrylonitrile, acrylamide, methacrylamide, N-substituted meth acrylamides, vinyl esters such as vinyl acetate, vinyl ethers such as isobutyl vinyl ether, styrene, alkyl- and halostyrenes, N-vinylpyrrolidone, vinyl chloride or vinylidene chloride.
Photoresist composition and method of manufacturing black matrix using the same. Grain enhancement with surfactants in water-based uv-radiation curable polyurethane dispersions. The term “alkoxylated liquid surface active agent” refers to compounds in which one or more straight or branched C 1 -C 22 alkyl chains are connected through the residue of a linking group to an oligomeric or polymeric chain of alkylene oxide residues.
These results show that the inventive liquid photoinitiator blends in addition to conventional non-aqueous UV systems, also give good curing performance in waterborne UV-paints.
Thus the inventive photoinitiator blends have a much broader applicability ranging from typical non-aqueous UV-paints up to aqueous UV-systems. This solution is not suitable for aqueous systems. Higher active contents are obtainable as compared to previous solutions like the waterborne dispersions of photoinitiators described in EP Lamberti and EPB1 Ciba and in GB Minesota Mining In addition the inventive homogenous liquid blends show better storage stability, especially at elevated temperatures, as there are no heterogeneous photoinitiator particles which may irreversibly settle like in the case of a dispersion.
LU Free format text: Examples of polyepoxides are those based on the abovementioned polyols, especially the aromatic polyols, and epichlorohydrin.
The optional organic diluent provides additional stability of the photoinitiator concentrate and assists in improving compatibility of the photoinitiator concentrate towards different end lne formulations.
Again the curing results demonstrate that the liquid photoinitiator blends provide useful good curing performance despite the dilution with blend components.
