The substrate is then rotated at speeds up to 10,000 rpm to spread the coating material by centrifugal force. A machine used for spin coating is called a spin coater, or simply spinner. [1] Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved.
There are four basic parameters that are involved in spin coating: solution viscosity, solid content (density), angular speed, and spin time. [13] A range of thicknesses can be achieved by spin coating. Most commonly the thicknesses range from 1-200 μm. The main properties that affect the thickness of the film are viscosity and spin speed.
Komatsu Limited and Dresser Industries established Komatsu Dresser to make mining tractors, construction equipment and related equipment. [15] This 50-50 ownership lasted from September 1988 to August 1994, when Komatsu bought out Dresser's share. [15] By 1993, it generated sales of more than US$4 billion, and employed 31,800 people in fifty ...
This allows creating thin films of various molecules such as nanoparticles, polymers and lipids with controlled particle packing density and layer thickness. [6] Spin coating or spin casting, uses a liquid precursor, or sol-gel precursor deposited onto a smooth, flat substrate which is subsequently spun at a high velocity to centrifugally ...
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
1970 — Nedox was invented, a coating that significantly increases metals' corrosion resistance and wear life. [5] 1980 — General Magnaplate opens its Ventura, California facility. [6] 1982 — General Magnaplate's Texas facility upgrades to its new Arlington location, and Candida Covino joins the company. 1985 — Ed Aversenti joins the company
Nordson Corporation is an American multinational corporation that designs and manufactures dispensing equipment for consumer and industrial adhesives, sealants and coatings. The company also manufactures equipment used in the testing and inspection of electronic components, technology-based systems for curing and surface treatment processes as ...
The company was founded in 1949 as Global Equipment Company, a material handler. It first entered direct marketing in 1972 and began marketing computer equipment in 1981. The company changed its name to Global Direct-mail, in 1995 and to Systemax in 1999 and Global Industrial Company in 2021. [4] Former Systemax logo
