Epoxy resins, which are frequently preferred among thermoset plastics in the industry, materials with high viscosity, and good mechanical performance. The biggest disadvantage of epoxy resins is that they encounter difficulties application alone due to their viscosity. For this reason, various diluents added reduce viscosity applications conducted. In study, properties resin, used many fields, ...

BACKGROUND Epoxy resin systems (ERSs), consisting of resins, reactive diluents, and hardeners, are indispensable in many branches of industry. In order to develop less sensitizing ERS formulations, knowledge of the sensitizing properties of single components is mandatory. OBJECTIVES To analyse the frequency of sensitization in the patients concerned, as one integral part of a research project...

Reactive diluents, small monomers with low viscosity, and reactive groups are widely used in UV-curable materials for additive manufacturing (3D-printing) to optimize the processability properties of cured objects. Most these such as acrylic acid esters, derived from fossil resources possess strong irritation allergenic potential. Therefore, more benign bio-based diluents UV-curing high interes...

The disadvantages of materials, which are currently used in orthopaedic surgery have led to the development of new synthetic biocompatible and biodegradable materials. Rapid Prototyping offers the possibility to fabricate cellular structures with nearly arbitrary form and structures out of photocurable liquid acrylate-based formulations by radical polymerization. Such a composition consists of ...

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 o...

The feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (TOMAC) as an extractant, was studied. The diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. The effect of initial acid concentration in t...

Epoxy resins, widely used as adhesives or coatings in construction, boat and aeroplane building, plastic and other industries and trades (1–3), are a frequent cause of occupational allergic contact dermatitis (1–6). Epoxy resin based on diglycidylether of bisphenol A is the main allergen responsible but sensitization can also develop to other components, including the hardeners and reactive dil...

The fertility (positive ultrasound scanning 60-75 days after insemination) of ram spermatozoa frozen in Tris- or zwitterion/glucose/egg yolk/glycerol-based diluents was examined during the natural breeding season (autumn). In Experiment 1 Tris-citrate, high glucose and Hepes-NaOH diluents were used and ewes (n = 266) were inseminated (induced oestrus) with 20 (uterus) or 180 (cervix) million mo...
