Bubbles in coating color greatly influence the paper quality and coater runnability. It is particularly important technology to remove bubbles for the paper coating industry. Recently, one of the authors has developed a novel device using swirl flow capable of eliminating bubbles and decreasing dissolved gases from fluid. This device is called the “Bubble Eliminator”. Using the bubble eliminato...

In cookware industry, interior spray coating process is an important process to protect the cookware product from the corrosion. In this process, the coating material “TEFLON” is used to spray to cover all the part’s surface. If a pot or pan is not too deep, one spray gun is enough to spray to cover all the interior surface. However, for the high side-wall pot, two spray guns must be used to sp...

Resin coating technique is a unique method that improves the dentin bond strength of resin cements in indirect restorations. However, the weak link of a specimen bonded using the resin coating technique was reported to be the bonded interface between the resin coating material and resin cement. The purpose of this study, therefore, was to enhance the bonding performance between a resin coating ...

Wear of the surface is the major problem of all materials. This wear can be of many types and there can be several methods of reducing wear. Coating on the surface of material is one of them. On M.S substrate, thermal spray coating is done using Detonation spray gun and coating powders used is a mixture of oxides (Al2O3-13TiO2). The thermal-sprayed coatings are characterized by SEM, EDS analyse...

Recently, an esthetic tooth coating material has been developed. The material consisted of a primer solution, a base coat, and a top coat. The purpose of this study, therefore, was to evaluate the color change of this tooth coating material and two resin composites after immersion in food-simulating, staining solutions. To this end, the newly developed coating material with and without its top ...

BACKGROUND Coronary guidewires are indispensable during percutaneous coronary interventions. Nowadays, most guidewires have hydrophilic coatings to improve their trackability, allowing easy lesion passage and facilitating balloon and stent positioning. Recent reports, however, have raised concerns about detachment and subsequent embolization of these hydrophilic coatings. METHODS AND RESULTS ...

A new strategy to seal mesoporous low-k thin films with a pore size of 3 nm has been developed. This is achieved by spin-coating of a self-assembled carbon-bridged organosilica layer followed by a grafting with hexamethyl disilazane.
