Low volatile monofunctional reactive diluents for radiation curable formulations
نویسندگان
چکیده
In the last decades importance of UV curable formulations has increased continuously. Their fast curing speed, solvent-free polymerization conditions, and formation hard highly crosslinked photopolymer networks represent major benefits. Commercial resins generally consist multi-functional vinyl oligomers, photoinitiators, additives, reactive diluents. Mono- diluents serve as thinners to lower overall resin viscosity improve processability. However, many monofunctional like isobornyl (meth)acrylate or benzyl exhibit high volatility, often already at room temperature. This causes adverse effects such unpleasant odor, potential health risks, changing composition during processing. A new group monomers that show for replacing traditional volatile are salicylate (meth)acrylates. this work, salicylate-based synthesized, polymerized, characterized with respect their viscosity, thermal stability, photoreactivity, thermomechanical properties homopolymers. Additionally, a first example diluting effect in viscous difunctional polyester urethane methacrylate is demonstrated 30 wt% cycloaliphatically an aromatically substituted methacrylate. The polymers diluted similarly glass transition temperatures 110 126 °C, which range undiluted resin.

Uv-curable Release Coating and Adhesive Formulations Containing Vinylethers
Vinylether monomers offer unique properties for UV/EB curing due to their efficiency as reactive diluents and their ability to undergo both cationic homopolymerization and free-radical copolymerization. The benefits derived from the inclusion of vinylethers into commercial UVcurable epoxysilicone formulations include viscosity reduction, improved cationic photoinitiator miscibility, and lower c...

OBJECTIVES The aim of this study was to develop a low shrinkage visible light curable nanocomposite dental restorative material without sacrificing the other properties of conventional materials. This nanocomposite was developed by using an epoxy resin 3,4-epoxycyclohexylmethyl-(3,4-epoxy)cyclohexane carboxylate (ERL4221) matrix with 55% wt of 70-100 nm nanosilica fillers through ring-opening p...

Until now, acrylates have been the monomers of choice for use for step and flash imprint lithography ~SFIL! etch barrier formulations, in part because of the commercial availability of silicon-containing acrylates ~necessary for etch resistance!, together with their low viscosities and capability for rapid photopolymerization. However, despite many desirable properties, the polymerization of ac...
متن کاملEffect of Hydrophilic Diluents on the Release Profile of Griseofulvin from Tablet Formulations
Studies have shown that when compressing drugs with low aqueous solubility, the solubility of diluents selected is very crucial as it influences the disintegration, dissolution and bioavailability of such drugs. Based on these reports, the present study was undertaken to investigate the effect of some commonly used hydrophilic tablet diluents (lactose, sucrose, mannitol and dextrose) on the in ...
