Characteristics of Materials

Only the main characteristics of the materials listed in
The Clean-Up lists present only the representative solvents used to wash the material. Even if a solvent is listed
as Clean-Up, confirm that the solvent does not react with the samples.
The Harm solvents can destroy the materials through corrosion or dissolving.
Some solvents not listed as Harm can be harmful to the materials.
