The Koldmount fast-curing cold mounting kit has become the worldwide standard for this kind of product. It results in a translucent block when finally cured. It can be used for embedding virtually any kind of sample. The cure time is 20-30 minutes at room temperature. In most instances, one would also need some mold release agent.
But we also have to be fair to our customers and give additional but very candid information about this type of product in general, including the Koldmount product offered by SPI Supplies. Basically there is only one reason why one would want to use this particular product: When there is the need for virtually an immediate turnaround time to have the completed the finished mount with the following condition that the sample can not be heated.
We say that because it is inferior in virtually every respect to more conventional embedding resins (for example, Bakelite or other resins) except one: You can make a mount ready to examine in a few minutes instead of over night.
So the real purpose of Koldmount in our product line is for those who absolutely must have speed without heat and the fact that the quality of the mount itself will be lower just does not matter. This is a product for fast turnaround time and high productivity and speed, it is not a product where one would obtain the highest quality metallographic preparation.
An understated potential safety risk:
We are addressing now the cured block, something that to most people is about as inert of a material as one will find. But the standard practice in many laboratories is to use a small jeweler's (or even a small hack) saw to cut the block down to the right size, sometimes even to shape it. We want to address the dust that is generated and how its exposure can and should be minimized.
