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 information esacurf here was acquired by UL from the producer of the product or material or original information provider. The formulations were stirred for a total of 15 min. Optionally the esavure may contain water. The term also refers to compounds in which one or more aromatic groups, which can be alkylated, are connected through the residue of a linking group to an oligomeric or polymeric chain of alkylene oxide residues.
Examples of monomers containing a double bond are alkyl or hydroxyalkyl acrylates or methacrylates, for example methyl, ethyl, butyl, 2-ethylhexyl or 2-hydroxyethyl acrylate, isobornyl acrylate, methyl methacrylate or ethyl methacrylate.
The term also refers to compounds in which one or more aromatic groups, which can be alkylated, are connected through the residue of a linking group to an oligomeric or polymeric chain of alkylene oxide residues.
The unsaturated esscure may include one or more olefinic double bonds.
Active-energy-ray-curable composition, active-energy-ray-curable ink, composition stored container, two-dimensional or three-dimensional image forming apparatus, two-dimensional or three-dimensional image forming method, cured material, and structure.
Again the curing results demonstrate that the liquid photoinitiator blends provide useful good curing performance despite the dilution with blend components. This product is a new high reactive difunctional photoinitiator particularly suitable for clear systems. Further examples eacure 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 The homogeneous mixture is cooled slowly to room temperature.

Examples of ether fluids are diethylene glycol dibutyl ether and phenoxyethanol Examples of alcohols are isodecanol, CC15 oxoalcohols, propylene glycol, dipropylene glycol, tripropylene glycol, oligoethylene glycols like diethylene glycol, triethylene glycol, tetraethylene glycol and glycerin.
Preferably, the pure surfactant is a liquid at room temperature. They often require longer times of mixing until a uniform distribution and dissolution has been achieved.
Examples of alkoxylates of alkine-alcohols or alkine-diols are product sold under the Oone HU Free format text: IE Ref legal event code: DK Free format text: Lamberti requires water to obtain a heterogeneous product form at room temperature. Lapsed in esacuge contracting state announced via postgrant inform.
A UV-curable paint is prepared using the following formulation:. As an aqueous dispersion there still remain disadvantages in that the photoinitiator particles may settle on prolonged storage and that the aqueous dispersion is incompatible to many non-aqueous UV-systems. Photoresist composition and method of manufacturing black matrix using the same.

The combination was stirred using a magnetic stirring bar for 5 min at approx. The extend of curing was followed by measurement of acrylate double bond conversion DBC against the resin itself as reference using AT-IR spectroscopy of the coating surface.
The photoinitiator samples were tested in 2 different water-based clear coat formulations. The inventive free flowing liquid is suitable for aqueous and solvent based systems.
Applications Products Highlights Technical support. The liquid blend has at room temperature a viscosity not higher than mPas and therefore can be processed as a liquid with standard technical equipment for pumping and mixing of liquid materials. NL Free format text: These results show that the inventive photoinitiator blends can be easily incorporated into a waterborne UV-formulation without giving defects to the paint film.
A further advantage is shown for the aqueous systems. Compared to the dispersed photoinitiator of EP Lamberti which is a heterogeneous system the present invention is a homogeneous system at room temperature. The acrylate peak at approx.
LU Free format text: The optional organic diluent provides additional esacurs of the photoinitiator concentrate and assists in improving compatibility of the photoinitiator concentrate towards different end use formulations.
The photoinitiator samples were tested in 2 different water-based clear coat formulations. The inventive free flowing liquid is suitable for aqueous and solvent based systems. The surfactant is e. Examples of block copolymers of ethylenoxide and propylene oxide are the products sold under the Pluronics trademark like: Curing agent for three-dimensional molded object, apparatus for manufacturing three-dimensional molded object, and program for manufacturing three-dimensional molded object.
Due to its molecular structure, it is particularly suitable for all systems where low VOC, low migration, and low extraction values are needed. With the widest variety of photoinitiators that upon exposure to UV light decomposes into free radicals that initiate a polymerization between diluting acrylates and acrylated oligomers, the free radical system is adopted for most applications.
TRGR Ref country code: The inventive homogeneous liquid blend is obtainable by a process comprising the steps of. These results show that the inventive photoinitiator blends can be easily incorporated into a waterborne UV-formulation without giving defects to the paint film.
