Mounting Material
Mounting specimens are generally required for providing a convenient way to hold a specimen while it is being ground and polished, or for preserving an edge for examination.

Mounting materials fall into two categories:
- Compression mounting materials
- Cold mount mounting materials
Compression mounting requires the use of heat and pressure in a mounting press to prepare a mounted specimen. Cold mounting is performed at room temperature using a two part castable system. Lapmaster's cold mounting process allows you to acquire Metallographic specimens faster due to the shorter set- time required by our product.
Compression mounting materials
- Phenolics - Phenolic material comes in three different colors - black, green and red. Phenolic material is economical, easy to use and cures quickly. Lapmaster offers phenolic materials in convenient 5 lb containers, but can also be purchased in larger bulk containers as well.
- Lucite - Lucite is a transparent compression mount material, which allows viewing into the specimen. Lapmaster offers Lucite material in convenient 5-lb containers.
- Dially1 Phthalate - This material is similar in nature to phenolic. It is blue in color, and has a
glass filler, which helps provide better edge retention than the standard phenolics.
Cold mounting materials
- Koldmount - Koldmount is a two part acrylic mounting system, which cures in approximately 30 minutes. Lapmaster offers Koldmount mounting materials in convenient 1 lb and 5 lb containers.
- Epoxy - Lapmaster features an epoxy mounting system, which offers excellent edge retention and good abrasion resistance. The epoxy cures in approximately 30 minutes. Lapmaster offers Epoxy material in convenient 32-ounce containers for the resin, and 16 ounce containers for the hardener.
- Fast cure acrylic - This cold mount, two -part acrylic mounting system has good flow characteristics and good penetration into holes and recesses. The cure time is approximately 5 minutes for this product.
- High performance mounting compound - This high performance-mounting compound has excellent flow characteristics due to its low viscosity. The compound produces sample mounts of high hardness and density with superior abrasion resistance and edge retention.
In addition to the mounting materials mentioned above, Lapmaster also offers a variety of mounting accessories:
- Mold release - Lapmaster offers mold release for hot and cold mounting applications. This mold release is used to help eject the specimen clearly from either the mounting press or mold. Mold release is available in aerosol spray form.
- Specimen clips - Specimen clips.are used to support specimens while the mounting material cures. Lapmaster offers both plastic and metal clips, which are packed in 100 piece containers.
- Mold cups - Mold cups are disposable molding forms. Lapmaster offers these mold cups in 1", 1.25" and 1.5" sizes.
