POLYESTER SYSTEMS - COLD MOUNTING SUPPLIES FOR SAMPLE PREPARATION

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. Characteristics of Polyester include: - Very clear (water clear) - High odor - Best resin system for making large castings

Cold Mounting systems are recommended for mounting specimens that are sensitive to high pressures and temperatures. Epoxy products provide good physical adherence, low shrinkage, and excellent infiltration into pores.

Polyester Systems - Cold Mounting
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.

Mounting accessories many different clips, cups, pigments, and fillers are available to help simplify, improve, or customize a mounting process.

High-Quality Mounts: Mounting cups are available in multiple shapes and sizes to create high-quality mounts with easy removal.

Consistent Specimen Alignment: Support clips allow for precise placement of the specimen in the mount to ensure the area of interest is properly presented for grinding and polishing.

Unique Mounting Applications: A variety of colored pigments, fillers, and cement offer many options to customize the mounting process to meet any lab's needs.
