Laurell Technologies WS-400 spin coater used to apply photoresist to the surface of a silicon wafer. Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.
Axalta traces its origins to the German firm Herberts Gmbh, which began in 1866 coating carriages before moving to automotive painting. Through later mergers the company became DuPont Performance Coatings (DPC), part of the American DuPont chemical empire, and was rebranded as Axalta Coating Systems after being purchased by The Carlyle Group in ...
A common issue in spin coating is a "beading" up of solvent at the edge of the silicon wafer. A process known as backside washing is most commonly used to spin this bead off of the wafer. By programming multiple different spin speeds into the spin coating apparatus the thickness of the solvent can be made uniform without the "beading" up at the ...
Spin casting is a favored method for fabricating items in the specified materials – low temperature metals and thermoset plastics. Compared to the two main competing processes, injection molding and (zinc) die-casting, spin casting has significant advantages in terms of startup cost and ease of use.
Fordite, also known as Detroit agate, Motor City agate, [1] paint rock, or paint slag, [2] is a lapidarist term for polished pieces of finely layered paint masses from automobile factories. The masses consist of automotive paint which has hardened sufficiently to be cut and polished.
Modern automobile paint is applied in several layers, with a total thickness of around 100 μm (0.1mm). Paint application requires preparation and primer steps to ensure proper application. A basecoat is applied after the primer paint is applied. Following this, a clearcoat of paint may be applied that forms a glossy and transparent coating.
Electrospinning shares characteristics of both electrospraying and conventional solution dry spinning of fibers. [1] [3] The process does not require the use of coagulation chemistry or high temperatures to produce solid threads from solution. This makes the process particularly suited to the production of fibers using large and complex molecules.
Burnout in the box at Tarlton International Raceway, South Africa Fire burnout, Santa Pod Raceway, UK. The origins of burnouts can be traced to drag racing, where they have a practical purpose: drag racing slicks perform better at higher temperatures, and a burnout is the quickest way to raise tire temperature immediately prior to a race.
