Microset 121 Forming Putty is a two-part synthetic rubber compound designed for macroscopic moulding 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.
Part A (yellow) and Part B (blue) are mixed in equal amounts by hand, until the compound is of a uniform colour. 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.
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.
The small electronic surface roughness tester KYR100 is designed for quick and accurate measurements. The gauge is suitable for use on the production floor as well as for inspection departments and quality control
KYPR100 uses a piezoelectric stylus and allows
Roughness measurement by Ra and Rz method
Three cut-off length at choice
KYR100 is simply placed on the surface to be measured and micro stylus scans the surface within only a few seconds. Depending on the preset cut-off length, the value is immediately displayed in Ra or Rz
Ra and Rz
Rz= mean surface roughness
The mean surface roughness Rz is the arithmetical mean of the highest single reading of several adjacent single measuring sections.
Ra= arithmetical average high
Ra is the generally acknowledged roughness parameter which is internationally used. This value is the arithmetical mean of the profile deviations from the mean value.
The numerical value is always smaller than the Rz value taken from the roughness profile.
KYR100 confirms to NIST calibration requirement, also DIN 4768 and ISO 4288.
