Key Applications & Uses
- High-precision mounting of metallographic samples for optical microscopy, SEM, hardness testing, and detailed microstructural evaluation in metals, ceramics, composites, and coatings.
- Encapsulation of delicate, heat- or pressure-sensitive specimens (e.g., thin films, electronic components, PCBs, soft materials, polymers, and biological-material interfaces) where clarity and edge preservation are critical.
- Failure analysis, inclusion studies, porosity evaluation, and fracture surface examination requiring transparent mounts for enhanced visual inspection.
- Routine and advanced sample preparation in universities, research institutes, pharma/biotech material characterization labs, and industrial QA/QC departments.
- Vacuum-assisted mounting for maximum penetration and elimination of air bubbles in porous or intricate samples, ensuring superior mount quality for subsequent grinding, polishing, and etching processes.

Frequently Asked Questions (FAQs)
Q: How does GHEXA-MNT-CON-EPO-012 compare to acrylic cold mounting resins? A: Epoxy provides superior clarity, better edge retention, lower shrinkage, and stronger adhesion, making it the preferred choice for high-precision work, transparent mounts, or samples requiring maximum detail preservation—though with a longer cure time than acrylics.
Q: Is vacuum impregnation recommended with this epoxy? A: Yes—its excellent flowability and low viscosity make it ideal for vacuum impregnation, ensuring complete penetration into porous or complex samples with virtually no trapped air bubbles.
Q: What is the best mixing procedure for optimal results? A: Accurately weigh Part A and Part B at the 4.5:1 ratio. Slowly add Part B to Part A while stirring thoroughly for 5-10 minutes to achieve a homogeneous mixture. Allow bubbles to rise and degas if necessary before pouring.
Q: Can this resin handle heat-sensitive or soft samples? A: Absolutely—it is a true cold mounting system with no external heat or pressure required, and its moderate exotherm (peak 125°C) is well-managed in standard use, protecting delicate specimens effectively.
Q: How do the package sizes work for ordering? A: Available as complete kits or separate components: 4.5 kg Resin + 1 kg Hardener (large labs), or 1 kg Resin + 230 g Hardener (smaller/R&D use). Contact G-Hexa for bulk pricing or custom configurations.
Q: What should I do if bubbles appear during curing? A: Ensure thorough mixing and consider brief degassing under vacuum after mixing. Pouring in a thin stream or using vibration can also help release trapped air for clearer mounts.
