Mounting

 

  • Mounting serves several different purposes:
  • Protection/support of the sample surface
  • Easier handling
  • Having several small samples in one mount
  • Having uniform sizes for clamping in sample holders

 

 

There are two different mounting methods; Cold and Hot Mounting; and several resins available that each have different strengths and advantages.

Cold mounting resins typically consist of two components that cure after being mixed together. Two different systems are available, epoxies and acrylics.

The epoxies consist of a liquid resin and a liquid hardener.

Our epoxy resin can be mixed with either the Aka-Cure Slow or Aka-Cure Quick hardener, depending on the requirements. Both have very good adhesion to the sample, which helps to provide the best possible edge retention. They can also be used for vacuum impregnation of fragile and porous samples like ceramics and plasma spray coatings.

We offer epoxy resin and hardeners separate, not as a kit, to make it easy to use either hardener with the resin.

Epoxies require good precision when mixing the two components. It can be measured by volume, but weighing is much more precise and the recommended method.

Our acrylic resin consists of a powder and a liquid.

Aka-Clear-2 is a fast curing, transparent system with a slightly yellowish tint. It cures in 8 minutes and produces totally clear, bubble-free mounts without having to use a pressure pot. Mixing of the 2 components is not critical, if a thinner mix is required, a little extra liquid can be added without adverse effect on the cured mounts.

With Aka-Clear powder we ship 2 measuring spoons, 2 reusable mixing cups and 25 wooden mixing pins for easy measuring and mixing of the resin. With the Aka-Resin Epoxy we ship the same, except the measuring spoons, as the epoxy resin and hardener should be measured by weight and not by volume.

Curing time

8-24 hours @ 22°C Long pot life and low peak
temperature, suitable for
both vacuum impregnation
and mounting of heat
sensitive samples. Not
suitable for large mounts
due to excessive exothermal reaction.

30 min. when heated to
80°C.
Peak temperatures up to
200°C.
For very hard, transparent
mounts. Very large mounts can be made using a 2 cycle curing schedule. First the mount is cured without heating in 8 hours, followed by a 1 h cycle @ 100°C.

8 -10 minutes @ 22°C
Peak temperature 90°C

Hot Mounting

Hot mounting resins are single compounds for use in mounting presses.

  • Aka-Resin, Epoxy is a black mineral filled thermosetting compound for perfect mounts with very low shrinkage and best edge retention.
  • Aka-Resin, Acrylic is a thermoplastic compound for crystal clear mounts for easy visibility of the sample.
  • Aka-Resin, Melamine is a white mineral filled thermosetting compound for universal mounting with low shrinkage. White color gives perfect contrast in hardness testing.
  • Aka-Resin, Phenolic SEM is a black carbon filled thermosetting compound for conductive mounting used in SEM work.
  • Aka-Resin, Phenolic is a black wood filled thermosetting compound for backfilling and mounting of routine samples.

Accessories for mounting

Here you find a range of accessories for Cold and Hot Mounting.
Moulds for all types of cold mounting resins. With built-in bevel to avoid ripping cloths or grinding paper while preparing samples. The moulds are available in sizes from 25 – 50 mm dia..

Mounting clips in stainless steel and in plastic for easy placement of samples while curing. The stainless steel springs are used for holding individual samples, and the plastic clips can hold up to three samples.
The plastic clips are standing on thin legs to minimize the contact of the softer plastic with the sample in the level of preparation. This reduces the risk of contamination and edge rounding.

Mould release products Aka-NoStick for both cold and hot mounting. For cold mounting Aka-NoStick Liquid is used to coat the inside of the moulds, and for hot mounting, Aka-NoStick powder is applied on the upper and lower ram of the mounting press to prevent the resin from sticking.
