ESACURE ONE PDF

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 European Patent EP Lamberti discloses an aqueous dispersion comprising a photoinitiator and a surfactant. The content of such third party sites is not within our control, and we cannot and will not take responsibility for the information or content. Further polyols which are suitable are oligoesters having rsacure end groups.

They may be of low monomeric or high oligomeric molecular mass.

Further examples of unsaturated oligomers are unsaturated polyester resins, which are usually esaccure from maleic acid, phthalic acid and one or more diols and have molecular weights of from about to FG2A Ref document number: This is in contrast to the reference Irgacurewhich due to the incompatibility does not give a useful waterborne UV-paint.

Compared to the dispersed photoinitiator of EP Lamberti which is a heterogeneous system the present invention is a homogeneous system at room temperature.

The invention further relates to a photopolymerizable composition comprising. Esacurs were handling, incorporation, curing efficiency and yellowing visual. Examples of suitable alkoxylated liquid surface active agents include also compounds in which a straight or branched C 1 -C 22 alkyl chain is connected through the residue of a linking group as defined above to multifunctional alcohols like trimethylolpropane, sugar derivatives like sorbitan esters, triglycerides like castor oil and the like.

EP EPB1 en However, UL assumes no responsibility or liability for the accuracy of the information contained on this website and strongly encourages that upon final product or material selection information is validated with the manufacturer. Acrylic and methacrylic acid are preferred.

Are esacurre a distributor who is interested in being listed here? A dispersion solid particles of the photoinitiator is obtained. Carbonyl derivatives of 1-phenylindan suitable for use as polymerization photoinitiators, their preparation and use.

CY Free format text: This solution is not suitable for aqueous systems. The product form is a clear yellowish liquid. Oxime ester derivatives of benzocarbazole compounds and their use as photoinitiators in photopolymerizable compositions.

Other options include dissolving the photoinitiators in the reactive diluent, dissolving a solid photoinitiator in esafure liquid one, and dissolving the photoinitiators in nontoxic, nonvolatile solvents that do not adversely affect coating properties. These results show that the inventive photoinitiator blends can be easily incorporated into a waterborne UV-formulation without giving defects to the paint film.

We’re sorry, but the industry you have esadure is not currently available in your chosen language.

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 inventive free flowing liquid is suitable esacire aqueous and solvent based systems. Examples of unsaturated carboxylic acids are acrylic acid, methacrylic acid, crotonic acid, itaconic acid, cinnamic acid, and unsaturated fatty acids such as linolenic acid or oleic acid.

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. Onne UV-curable paint is prepared using the following formulation:. Higher active contents are obtainable as escaure 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 esacuge which may irreversibly settle like in the case of a dispersion.

Table 1 shows that the reactivity of Example 9 is comparable to Esacure KIP in the pure product form. NL Ref legal event code: By contrast, Example 9 had a viscosity similar to honey and could be directly poured into the OPV. Also suitable are high boiling liquid alcohols like C10 to Calcohols or polyols. The problem underlying the present invention is to provide noe liquid photoinitiator blend which remains liquid and homogeneous i. This is in contrast to the reference Irgacurewhich due to the incompatibility does not give a useful waterborne UV-paint.

The surfactant is e.

Benzene, (1-methylethenyl)-, homopolymer, ar-(2-hydroxymethyloxopropyl) derivs. |

The product form is a clear, colorless to yellow liquid. 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. Year of fee payment: The surfactant can be a blend of all classes of alkoxylated surface active substances described previously.
