Soluble Thermo Polymers

Doing a little reading on Hackaday.com and one of the posts describes the polymers using to hold silicon wafers during milling.

Crystal Bond


Typical Applications:

• Machining advanced ceramics.
• Lapping and polishing optical components.
• Dicing ceramic substrates and semiconductor wafers.
• Dicing ferrites, glasses and piezoelectrics.
• Dicing metal and optical single crystals.
• Mounting cross-sections for electron microscopy.
• Backfilling components for temporary mechanical support.

A couple interesting things about this:
-different material solvents (acetone, water, methanol)
-low softening point should allow for other plastics to adhere to the prior layers.

i think this may be useful for printing rafts or even as a support material assuming there is no significant shrinkage as it cools.

Any opinions before I purchase a stick?
