The hot embedding of metallographic samples can provide protection and support for the surface of the sample, making subsequent grinding and polishing easier. Hot embedding resin is a single component compound used in embedding machines, which unifies the size of the sample under high pressure and high temperature, making it easy to clamp it in the sample fixture seat of the polishing machine for grinding and polishing.



Denmark's Akasel offers a variety of thermal inlay compounds for you to choose from based on specific thermal inlay processes!



Type of hot embedded resin



&Bull; Aka Resin, Phenolic phenolic resin, a thermosetting resin filled with black wood powder, used for conventional sample setting. Phenolic resin is cheaper and more popular than other hot setting resins.



&Bull; Aka Resin, epoxy resin, black mineral powder filled thermosetting resin, with extremely low shrinkage and excellent edge protection. This allows the sample to be inspected at a high magnification and avoids cross contamination as there is no gap between the resin and the sample.



&Bull; Aka Resin, Melamine melamine resin, a thermosetting resin filled with white mineral powder, has comprehensive adaptability and low shrinkage rate. During the hardness testing process, white has good contrast.



&Bull; Aka Resin, Acrylic acrylic resin, thermoplastic resin, transparent, easy to clearly observe the sample.



&Bull; Aka Resin, Phenolic SEM phenolic conductive resin, a thermosetting resin filled with black carbon powder, has conductivity and is used for SEM testing.

  The difference between thermosetting and thermoplastic properties
  
  
  
  Thermosetting resin cures at a certain temperature, and this process is irreversible. Thermoplastic resins soften at high temperatures and harden or solidify again during the cooling process, which is reversible. If the inlay effect is not satisfactory, you can put it back into the inlay prototype and repeat the inlay process.
  
  
  
  3、 Backfilling
  
  
  
  Backfilling is the combination of two different resins.
  
  
  
  For example, using high-quality epoxy resin at the bottom of the sample to achieve ideal edge protection, and backfilling with cheaper phenolic resin to reduce the cost of sample setting.
  
  
  
  Another example is filling melamine resin to normal height?, Insert a piece of paper with sample identification, then backfill with acrylic resin to complete the sample setting
  
  
  With a transparent top, samples can be identified at any time.
