Acrylate polymers are derivatives of acrylic acid, but contain a plethora different functional groups and best discussed by themselves. In this column, we study the spectrum an important polymer, polymethyl methacrylate (PMMA), which is otherwise known as plexiglass, found in windows, car parts, paint. We then spectra PMMA mixtures copolymers detail.

Paints are used to protect and prolong the life of natural synthetic materials as it acts a barrier against environmental conditions. contain extenders, solvents, pigments, binders, some additives.

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...

3D printing using thermoplastics has become very popular in recent years, however, it is challenging to provide a metal coating on 3D objects without using specialized and expensive tools. Herein, a novel acrylic paint containing malachite for coating on 3D printed objects is introduced, which can be transformed to copper via one-step laser treatment. The malachite containing pigment can be use...

Likelihood ratios (LRs) provide a natural way of computing the value of evidence under competing propositions. We propose LR models for classification and comparison that extend the ideas of Aitken, Zadora, and Lucy and Aitken and Lucy to include consideration of zeros. Instead of substituting zeros by a small value, we view the presence of zeros as informative and model it using Bernoulli dist...

Color gamuts of acrylic paints generated by paint mixing and varnishing is introduced. A colorant data including unit k, unit s, and Saunderson coefficients, K1 and K2, are optimized. The simulation result of paint gamut rendering contradicts a belief of color mixing theory that yellow, blue, and red primaries produces any green. In addition, a statistic gloss model shows that varnishing makes ...

UNLABELLED The use of ocular prostheses for ophthalmic patients aims to rebuild facial aesthetics and provide an artificial substitute to the visual organ. Natural intemperate conditions promote discoloration of artificial irides and many studies have attempted to produce irides with greater chromatic paint durability using different paint materials. OBJECTIVES The present study evaluated the...

Paint systems containing color-change or fluorescing compounds were found to be sensitive to underlying corrosion processes by reacting to the pH increase associated with the cathodic reaction that accompanies corrosion. The sensitivity of acrylic-based coating systems for detection of cathodic reactions associated with corrosion was determined by applying constant cathodic current and measurin...
