How to cold mount with epoxy resin - QATM

The term cold mounting covers all mounting methods that do not require the use of a hot mounting press. More info www.qatm.com/p...
To create a optimal cold-embedded specimen, consider the following:
🔸 The specimen must not be affected or corroded by the resin selected for cold mounting
🔸 The specimen must be able to withstand the peak temperature of the mounting system.
🔸 To prevent gap formation, the specimen surface must be free of dust and grease before mounting, so that the specimen can be well wetted with the mounting medium.
The Qpox 94 used in this video is a low-viscosity and transparent two-component epoxy-based cold mounting resin, ideal for samples with delicate and complex geometries. It is particularly suitable for sensitive and porous surfaces as well as target preparations. With a curing time of about 9 hours Qpox 94 allows transparent and gap-free mounting and preparation on the same day.
