Cold Mounting Compound
Thermosetting polymer powder specially designed for metallographic sample hot mounting, with good fluidity, fast curing, high hardness and low shrinkage. It firmly encapsulates various metal, alloy and non-metal samples, providing stable support for subsequent grinding and polishing, ensuring sample edge integrity and smooth mounting surface.
Hot Mounting Resin is a specialized thermosetting polymer consumable for metallographic sample hot mounting process, serving as a core material to fix and protect samples before grinding and polishing. Made of high-quality raw materials with precise formulation, this resin powder features excellent thermal stability, uniform particle size and good fluidity under high temperature and pressure, enabling full and even encapsulation of samples without gaps or bubbles.
After high-temperature and high-pressure curing in a standard hot mounting press, the resin forms a solid, high-hardness mounting block with extremely low shrinkage rate, effectively preventing sample loosening, edge chipping, cracking and deformation during subsequent grinding and polishing operations. It is widely suitable for encapsulating various regular and small-sized metal samples, alloy parts, non-metal materials and thin sheets, providing stable and flat clamping support for automatic or manual grinding and polishing, ensuring the integrity of sample microstructure and improving the accuracy of metallographic observation. This resin is fully compatible with all standard desktop hot mounting presses, matching conventional mounting molds and supporting efficient batch sample mounting.
