Photoinitiatoren chemie
WebPhotoinitiatoren sind chemische Verbindungen, die nach Absorption von ( UV-) Licht in einer Photolysereaktion zerfallen und so reaktive Spezies bilden, die eine Reaktion starten (initiieren) können (meist eine Polymerisation ). Bei den reaktiven Spezies handelt es sich um Radikale oder um Kationen . Photoinitiatoren werden meist nach Art der ... WebCationic resins. Lambson™ product line offers a full range of cationic resins, including cycloaliphatic epoxy resins, valued for their high adhesion, low shrinkage and chemical resistance, and oxetanes, used in conjuction with cycloaliphatic epoxy resins, to improve speed of cure, viscosity control, hardness and adhesion to difficult substrates.

WebIrgacure Photoinitiator Irgacure Photoinitiators are products of the CIBA-GEIGY Corporation. The photoinitiator selected for this study was 1-benzoyl cyclohexanol (Irgacure 184 from Ciba Geigy), a compound known for its high initiation efficiency and the weak coloration of its photoproducts.The multifunctional monomer was an epoxy-diacrylate derivative of bis … WebAs bisacylphosphine oxides are highly efficient, cleavable photoinitiators for visible light curing, we were interested in preparing diacylgermane 2. The UV–vis absorption maximum of the n−π* transition was red-shifted up to 50 nm. Photo-DSC results of 2 showed similar reactivity to bisacylphosphine oxides under broadband irradiation experiments. Irradiation …
WebIntroduction. Photoinitiators are compounds added to a formulation to convert absorbed light energy, ultraviolet or visible light, into chemical energy in the form of initiating species, typically free radicals. Traditionally these molecules are engineered for non-polar environments with hydrophobic moieties rendering them water-insoluble.

WebPhotoinitiators for white coatings, usually pigmented with TiO 2, require strong absorption in the relatively narrow spectral region of 360–400 nm, below which TiO 2 absorbs strongly and above which the photoinitiator is colored (owing to selective absorption of visible light). Thioxanthones (TX) satisfy this criterion. Combinations of thioxanthones and PI 1 …
