Hot Mounting Resins - An Introduction

Spectrographic supplies several different hot mount solutions for differing metallurgical applications. 

Below is an overview of each resin that can be supplied, with the Omegapress 2 mounting press or can be used with other mounting press brands.




Carbon Conductive Hot Mount

The ideal compound for hot mounting of samples for observation using a scanning electron microscope.  The carbon content within the media offer a electrical conductive mounted sample.

The cycle time is dependent of the mounting press used but we recommend the same parameters as standard bakelite.


Clear Mounting Compound


Clear mounting compound designed for use in a hot mounting press. This is a thermosetting resin which is heated at 150 to 180 degrees c. The cooling process is extended to prevent clouding of the resin.





Diallyl Phthalate Media


High quality edge mount compound for superior edge retention. This is a blue resin which is used in a hot mounting press for encapsulation of metallurgical samples with special attention to the edge of the sample.

Epoxy Hot Mount

The use of Epoxy hot mount resin gives the best combination of hardness and edge retention. This will offer a best edge retention. It is recommended that samples are de-greased prior to mounting to get the best benefits.

Epoxy hot mount media is used as a face to standard bakelite product to give the improved quality at the sample.

Glass Fibre Filled Compound

Glass fibre filled edge mount offers improved edge retention compared to standard bakelite, phenolic resin.  The mounting operation is just the same, We can use the edge mount as a face and back up with phenolic or make complete mounts.

Good edge retention minimises leak back during preparation and improves the quality and consistency of metallurgical sample preparation.

Phenolic Black/Red Compound.

This is a high quality superior grade bakelite phenolic resin offering black/red mounts to give high contrast when viewing on the microscope. We can offer support for use on all types of mounting press.

The bakelite resin is a cost effective media suitable for most application offering good edge retention and can be used as a base for higher quality edge mount resins.

Still not sure which is the best resin for your application, then please contact our technical team.
