This temperature/time configuration is dependent on the coating material and the product manufacturer, as each manufacturer of zinc flake products has its patented formula. Typical curing temperatures are 200 °C, 240 °C and 320 °C. After the curing, a uniform, thin, firmly bonded and dry layer is produced.
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. This fluid bridge is commonly referred to as the coating meniscus or coating bead. The thickness of the resulting wet coated layer is controlled by tuning the ratio between the applied ...
An angle bracket or angle brace or angle cleat is an L-shaped fastener used to join two parts generally at a 90-degree angle. It is typically made of metal but it can also be made of wood or plastic. Angle brackets feature holes in them for screws. A typical example use of is a shelf bracket for mounting a shelf on a wall.
TIME-SERT insert. A threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. [1] They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or ...
This shape allows one to place the test panel on an angle to the anode. As a result, the deposit is plated at a range current densities along its length, which can be measured with a Hull cell ruler. The solution volume allows for a semi-quantitative measurement of additive concentration: 1 gram addition to 267 mL is equivalent to 0.5 oz/gal in ...
Spin coating is widely used in microfabrication of functional oxide layers on glass or single crystal substrates using sol-gel precursors, where it can be used to create uniform thin films with nanoscale thicknesses. [6] It is used intensively in photolithography, to deposit layers of photoresist about 1 micrometre thick. Photoresist is ...
