POLYESTERS are typically used when a very clear mount is required.
Polyester resins are also useful for mounting parts for display.
In this case, the part appears suspended in the plastic.
The procedure for molding samples for display is to first determine the mixing ratio of the resin to hardener (catalyst).
This ratio is variable depending upon the mass of the casting.
For larger volumes, the amount of hardener needs to be reduced significantly.
The procedure for suspending the sample in the mount is to pour an initial layer and allow it to pot or gel (do not let it fully cure).
The object or specimen is then placed on the initial rubbery polyester layer and another layer of the liquid polyester is poured.
Multiple layers can be poured in this fashion if required.
Characteristics of Polyester
- Very clear (water clear)
- High odor
- Best resin system for large castings
