For the preservation of painted cultural heritage on wooden substrates, it is important to understand fracture mechanisms in multilayer system which they are constructed and how environment plays a role composites’ physical properties. Past research has investigated material response each constituent layer but much more needs be done represent heterogeneous composite structure easel paintings. ...

Contemporary muralism is one of the most widespread manifestations urban art in cities nowadays. Loss colour (fading) due to degradation pictorial materials main deterioration this type artwork. However, application protective coatings considered slow down fading. In study, two acrylic-based were applied selected areas a real mural painted with six different alkyd paints and acrylic paint. The ...

The utilisation of rice husk ash (RHA) as an aluminosilicate source in fire-resistant coating could reduce environmental pollution and can turn agricultural waste into industrial wealth. overall objective this research is to develop a rice-husk-ash-based geopolymer binder (GB) fire-retardant additive (FR) for alkyd paint. Response surface methodology (RSM) was used design the experiments work, ...

The influence of polluting gases on the stability polymeric films has not been studied extensively. In fact, chemical interactions such materials in contact with ambient atmosphere depend different factors as environmental conditions, manufacturing process product, presence additives or various pigments. this study, accelerated artificial gas ageing was carried out. experiments were performed a...
