Replicating with Microset
Surface replication has been employed in engineering for many years, particularly for in situ high resolution metallography. Microset replicating compounds have a resolution better than 0.1 microns (4 x 10–6 inches) and can be used not only for metallography but also for a multitude of other purposes including 3-D applications.

These specially formulated two-part polymers are supplied in cartridges and dispensed as fully mixed semi-viscous liquids, using simple dispensing guns and mixing nozzles. They cure quickly to produce flexible high resolution replicas which can be peeled from the surface. When viewed microscopically under coaxial illumination, they have a bright metallic appearance, allowing detail such as microstructure, micro-cracking and pitting to be observed at high magnifications. These characteristics make the technique very suitable for the assessment of defects on critical engineering surfaces.
