MicroSet Forming Putty

MicroSet Forming Putty

Two Part, High Viscosity Compound for Macroscopic Molding of Surface Geometry

Overview

Microset Products Ltd manufacture high-resolution replication materials for engineering inspection. We supply to the Aerospace, Nuclear, Oil, Gas and Marine engineering industries. Microset 121 Forming Putty is a two-part, high viscosity, synthetic rubber compound designed for macroscopic molding of surface shape and form. The product is supplied in two versions, fast curing 121F and slow curing 121S to facilitate ease of use over a wide range of temperatures. Typical applications include surface damage and surface finish assessment, quality control of internal surfaces and dimensions, crack detection and metallography. Microset materials are used where conventional NDT methods are impractical.

Replicating with Microset Putty

The two components, Part A (yellow) and Part B (blue), are mixed in equal amounts by hand, until the compound is of a uniform color. The mixed compound is then pressed firmly onto the area of interest and left to cure. Additional amounts of putty can be applied to build up thickness or increase the area of coverage. The mixed compound cures to form a hard but flexible rubber.

Rigid Backing

One important use of Microset 121 putty is for producing a rigid backing for the more flexible Microset 101 replicating compounds. In order to use this putty in this way, first produce a Microset 101 replica of the area of interest. Allow the replica to cure but do not remove it from the surface. Apply mixed 121 putty to the back of the Microset 101 replica to the required thickness and allow to cure. The putty will bond to the Microset 101 replica and act as a dimensional support.

Replica Examination

When viewed microscopically under coaxial illumination, Microset replicas have a bright metallic appearance, allowing detail such as microstructure, micro-cracking and pitting to be observed at high magnifications. These characteristics make Microset replication ideal for the assessment of defects on critical engineering surfaces. Microset replicas can be examined using various techniques including: Microscopy, Stereo Macroscopy, 3D Infinite Focus Microscopy, Scanning Electron Microscopy, Atomic Force Microscopy, White Light Interferometry, Shadowgraph Measurement and 3D Laser Measurement.

8400K Optical Depth Measuring Micrometer

The 8400K is a portable inspection microscope with depth measurement capability. It quickly and accurately measures the depth of surface damage, is easy to operate, portable and durable. The 8400K Optical Micrometer Kit, when used in conjunction with Microset compounds, provide a quick and convenient method of obtaining precise measurements of damage in hard to reach places.
