Painting types include fine art to decorative and functional objects spanning from acrylics, frescoes, and oil paint on various surfaces, egg tempera on panels and canvas, lacquer painting, water color and more. Knowing the materials of any given painting and its support allows for the proper restoration and conservation practices.
Paint remover is applied to an aircraft's landing gear during an inspection looking for cracks in the aluminum. Paint stripper or paint remover is a chemical product designed to remove paint, finishes, and coatings, while also cleaning the underlying surface. Chemical paint removers are advantageous because they act on any kind of geometry and ...
A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles. Limescale is either white or brown in colour due to the presence of iron compounds. Glass surfaces may also exhibit scaling stains, as can many ceramic ...
In addition to the most obvious component, glass, all windows will typically involve some sort paint or stain as decoration, metal strips, or 'cames' used to join the pieces of glass together, waterproofing materials, and fixing systems or frameworks used for additional support (Brown et al. 2002; Vogel et al. 2007).
The Environmental Protection Agency said Tuesday it has finalized a ban on consumer uses of methylene chloride, a chemical that is widely used as a paint stripper but is known to cause liver ...
Low-VOC paint types include latex (water-based), acrylic, and milk paint, with most relatively easy to recycle. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC.
The recommended handling method for panel paintings is similar to that of canvas and other two-dimensional works. Conservators are the only persons that should touch the front or back of a painting. The panel should be held by the edges using nitrile gloves and carried with two hands or in tandem by two people, depending on size.
Dealkalizing glass containers is accomplished by exposing the glass surface to reactive sulfur- or fluorine-containing compounds during the manufacturing process. A rapid ion-exchange reaction proceeds that depletes the inside surface of alkali, and is performed when the glass is at high temperature, usually on the order of 500–650 °C or ...
