We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across different sublayers, while it can be neglected within each of the sublayers. Based on this assumption, an efficient recursive procedure of assembling the layers is developed, which...

Isocyanate-free cathodic ED coatings. Most of the resins used in the cathodic electrodeposition (CED) coatings are made from modified epoxy resin and blocked polyisocyanate in which the crosslinking is achieved by polyurethane and polyurea formation. A resin system has been developed that is isocyanate free and avoids not only the toxicity aspect, but also, to a great extent, the weight loss of...

Organic coatings act as a barrier to a corrosive solution and check the transfer of electrical charge from the corrosive solution. High performance organic paint systems were applied on plain carbon steel substrate with two different primers viz., epoxy Zn phosphate and epoxy Zn rich. Identical intermediate and top coats were applied on them having equal dry film thickness. Both uncontrolled lo...

In this study we estimated the number of housing units in the United States with lead-based paint and lead-based paint hazards. We included measurements of lead in intact and deteriorated paint, interior dust, and bare soil. A nationally representative, random sample of 831 housing units was evaluated in a survey between 1998 and 2000; the units and their occupants did not differ significantly ...

A polychlorinated biphenyl (PCB) that was not produced as part of the Aroclor mixtures banned in the 1980s was recently reported in air samples collected in Chicago, Philadelphia, the Arctic, and several sites around the Great Lakes. In Chicago, the congener 3,3'-dichlorobiphenyl or PCB11 was found to be the fifth most concentrated congener and ubiquitous throughout the city. The congener exhib...

Recent advances in paint technology have guided the development of novel “ready-to-use” paint formulations in which microencapsulated insecticides, or active ingredients (AIs), are embedded in the paint matrix and gradually released on the surface of the dried paint [1]. It is argued that the slow-release mechanisms enable uniform AI surface concentrations with prolonged residual effect, as com...

The incorporation of a commercially available coprecipitant into the AMPLICOR enterovirus PCR test specimen preparation enhanced the sensitivity and reproducibility of this assay. Fifty-five previously tested archived cerebrospinal fluids (CSF) specimens were tested in a blind study in duplicate with and without Pellet Paint coprecipitant (Novagen, Inc., Madison, Wis.). Of these specimens, 26 h...

In situ imaging nanoindentation was used to characterize the mechanical properties of pure paint films on eight types of plywood-based flooring with different wear resistance. Correlation between the mechanical properties of paint films and the wear resistance of wood-based floorings was investigated. The average modulus of elasticity (MOE) and hardness of the paint film tested were 3.33–5.77 a...

The outside appearance of cars is mostly defined through only two distinct materials – glass and car paint. While glass can rather easily be simulated by the simple physical laws of reflection and refraction, modeling car paint is more challenging. In this paper we present a framework for the efficient acquisition and realistic rendering of realworld car paint. This is achieved by building an e...

Abstract The paper considers an approach to monitoring the condition of treated surface in real time based on laser-induced breakdown spectroscopy technique. As a result study, aluminum alloy was cleaned from plimer coating, spectral analysis carried out, relationship between processing modes and thickness coating being removed experimentally established, which allows removing paint one pass wi...
