Photo-oxidative Stability of a Series of Red Acrylic Paints
Photo-oxidative stability of a series of most common red acrylic paints has been investigated. The paints in question were carmine, quinacridone scarlet, alizarin crimson, brilliant red, vermilion and cadmium red hue. Structural changes, discoloration and weight loss of paints film subjected to UV irradiation in an accelerated ageing chamber were measured using FT-IR spectroscopy, colorimetry a...
متن کاملMechanical properties of a hydrophilic acrylic polymer.
Acrylic polymers with hydrophilic groups (i.e., ethyl hydroxyl) may be prepared that convert to a soft elastic gel by absorbing water. Such a polymer has been applied t o dentistry for use as an elastic lining material for dentures. A commercial product, Hydron, was used in this study. The linear expansion of this material after 520 hr of water immersion was found to be 20.4%. Hardness was foun...
متن کاملConservation of artists' acrylic emulsion paints: XPS, NEXAFS and ATR-FTIR studies of wet cleaning methods†
Works of art prepared with acrylic emulsion paints became commercially available in the 1960s. It is increasingly necessary to undertake and optimise cleaning and preventative conservation treatments to ensure their longevity. Model artists' acrylic paint films covered with artificial soiling were thus prepared on a canvas support and exposed to a variety of wet cleaning treatments based on aqu...
متن کاملCandidacidal effect of fluconazole and chlorhexidine released from acrylic polymer.
OBJECTIVES To investigate the efficacy and rate of killing of a fluconazole- or chlorhexidine-impregnated polymeric delivery system against fluconazole-susceptible and -resistant Candida albicans and fluconazole-resistant Candida glabrata. METHODS Poly(ethyl methacrylate)/tetrahydrofurfuryl methacrylate (PEM/THFM) discs impregnated with chlorhexidine, pure fluconazole (FLCp) or fluconazole fr...
متن کاملAcoustic Performance of Resilient Materials Using Acrylic Polymer Emulsion Resin
There have been frequent cases of civil complaints and disputes in relation to floor impact noises over the years. To solve these issues, a substantial amount of sound resilient material is installed between the concrete slab and the foamed concrete during construction. A new place-type resilient material is made from cement, silica powder, sodium sulfate, expanded-polystyrene, anhydrite, fly a...
