Uv Curable Materials with Non-Polar Binders - Properties and Limitations
Non-polar polyols with either hydrocarbon or fluorinated hydrocarbon backbones were used in UV curable systems. This was camed out either by direct addition of non-polar polyols (in dual curing systems with additional isocyanate crosslinking) or by the synthesis of urethane acrylates with hydrophobic units. The dual curing formulations showed many
Anm in situ Technique for Monitoring Curing Process of UV-Curable Adhesives Using Relative Conductivity
We investigated the cure kinetics of the cationic UV-curable adhesives containing cycloaliphaticepoxide, oxetane and £-caprolactone poiyol using a specially designed sensor consisted of two ITO (Indium Tin Oxide)-coated glasses and a spacer sandwiched between them. This instrument is based on the determination of a function of electrical cond
Polymerization Kinetics and Characterization of Dual Cured Polyurethane-Acrylate Nanocomposites for Laminates
In last years, many studies have been devoted to develop exfoliated polymer nanocomposite based on fillosilicates exhibiting novel properties, such as a decreased oxygen permeability a good optical transmittance (i.e. low haze) (21 and an enhanced thermal stability and flexural mechanical modulus The clay-polymer composites have been generally divi
UV-curable powder coatings, combining of the attributes of the thermoset coatings and the radiation curing made possible the creation of environmentally friendly coating for heat sensitive materials including thermoplastic and wood 1-7]. Photochemical curing occurs by a free radical mechanism with unsaturated moieties or by a cationic mechanism wit
Investigation of Phenylglycine Derivatives as Coinitiators
Photoinitiators (P1) represent one of the key components in radiation curable for dental applications is camphorquinone (CQ). This initiator belongs to the class of Type II Pls reacting by bimolecular hydrogen abstraction from suitable amines such as ethyl 4-dimethylaminobenzoate (DMAB) acting as coinitiator 34 The first step in this reaction is a
How to Avoid the Back Electron Transfer in Type II Photoinitiators
Benzophenone (BP) and camphorquinone (CQ) are long known Type II photoinitiators (PIs) for the radiation curing of Coatings, printing inks, etc. After excitation, the P1 is able to abstract hydrogens from the resin such as from ether functionalities, thus generating reactive radicals on the backbone of the oligomers. Nowadays, amine-based coinitiat
The photoinitiator (P1) plays a key role in UV-curable systems by generating the reactive species, free radicals, or ions, which initiate the polymerization of the multifunctional monomers and2 This component has a great influence on. the curing rate and curing depth, the double-bond conversion (DBC), and the storage life and surface cure of such f
