Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens.n such uses, the curing agent mixed with the resin contains what is loosely referred to as a  catalyst , but which is more technically an initial source of free radicals (such as MEKP) to act as an initiator in a free-radical chemical chain reaction polymerization.
A pack of 5 carrier sheets. These are designed to scan fragile documents, photos and in the case of Fujitsu's associated A4 format scanners folded A3 size documents can be scanned and automatically stitched together on screen.
In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal ) that is modulated (modified) with an input signal for the purpose of conveying information. This carrier wave is usually a much higher frequecy than the input signal.
