It is typically used for lapping and polishing optical, ceramic and semiconductor components, dicing, and mounting cross-sections for SEM/TEM analysis. While mounting wax can be used with samples of any size, it is easier to achieve a uniform wax thickness when preparing smaller samples (≤ 10 mm2). Acetone can be used to dissolve/remove the wax after use, as well as to thin the wax for improved sample registration. For ease of use, apply the wax to a heated fixture. Instructions for Use 1. Heat a fixture on a hot plate at 150 ºC. 2. Place a small amount of mounting wax on the surface of the fixture. 3. Once the wax is soft, place the sample on the fixture. Note: For an ultra-thin layer, dip a cotton-tipped applicator in acetone and run it along the wax layer until the wax appears hazy and has no clumps. 4. Remove the fixture from the hot plate and allow it to cool at room temperature. 5. To remove the sample after preparation, place the fixture back on the hot plate and reheat the wax. Once the wax is soft, remove the sample; the wax can be reused. Note: Do not quench the fixture to cool the wax; the wax may become brittle, causing the sample to break off. For some samples, a mount leveling press (#120-30020) can be used to even out and thin the wax layer, improving registration between the sample and fixture.

It is typically used for dicing, thin sections and parallel delayering. While sheet wax can be used with samples of any size, it is easier to achieve a uniform wax thickness preparing larger samples (≥ 10 mm2). Instructions for Use 1. Cut out the sheet wax to fit the required sample shape. 2. Remove the lining from the back of the sheet wax, place the wax on a fixture/paddle and place the sample on the wax. 3. Place the fixture with the sample and wax on a hot plate at 150 ºC. 4. The wax will be completely melted when all the bubbles have spread out creating an even uniform layer. 5. Remove the fixture from the hot plate and allow it to cool at room temperature. 6. To remove the sample after preparation, place the fixture back on the hot plate and reheat the wax. Once the wax is soft, remove the sample. Sheet wax is not as effective after the first use, since the wax layer has already been thinned out. Note: Do not quench the fixture to cool the wax; the wax may become brittle, causing the sample to break off. This wax is more resistant to acetone, so Wax Dissolver can be used to remove the wax from the sample and fixture after use. Sheet Wax Flow Point 100 °C Tensile Strength 120 psi Shore Hardness 80 A Solvent Wax Dissolver Wax Dissolver (#71-10210) Use wax dissolver to thin or remove sheet wax. It can be applied directly to the wax with a cotton-tipped applicator or wipe.
