High-Performance Resins and Polymers for Metallographic Samples

Protect Delicate Samples

Cold mounting cures chemically at room temperature, eliminating the heat and pressure associated with hot mounting. This makes it ideal for brittle, heat-sensitive, or soldered components that could otherwise warp, crack, or lose structural integrity. Samples retain their original microstructure and dimensional stability, ensuring accurate analysis.

Preserve Fine Details 

Low-viscosity resins flow easily into cracks, pores, and voids to fully support the specimen. Once cured, the mount secures the sample with crisp edge definition, preventing chipping or material loss during grinding and polishing. Critical features, such as thin coatings, plating layers, or brittle phases, remain intact for reliable microscopic evaluation.

Simple and Flexible Preparation

Cold mounting provides a lower-capital entry into preparing metallographic samples. Preparing resins or epoxies is accessible for any lab and supports batch curing to improve throughput. The LECOMAT Pressure Vessel can further enhance results by reducing bubbles and improving clarity.

Speed and Strength

Multiple resin chemistries allow users to balance turnaround time and performance. Fast-curing acrylics enable rapid sample prep, while epoxies minimize the risk of shrinkage for demanding applications. Polyester options provide an economical middle ground for routine work, giving laboratories the flexibility to match media to both sample type and timeline.

Improved Efficiency

Finished mounts form durable, standard-size discs that are easy to label, handle, and load into polishing equipment or automated analysis systems. Formulated for compatibility with common abrasives, the mounting material maintains flatness and edge retention without interfering with the specimen, supporting accurate and repeatable hardness testing and microstructural imaging.

The LECOMAT provides the ideal curing environment for cold-curing acrylic resins. The space-saving, compact unit maintains constant operating pressure of 2.0 bars (29 psi). Simple to operate, an analog dial shows pressurization, and a digital timer tracks curing time.
