Main scope of application: |
| |
- universal
- industrial applications;
flanges, pipelines, equipment, motors, pumps, compressors a.m.
- in
varying media:
- gear-hydraulic-motor-oils,
fuels, solvents, hydrocarbons, coolants, ester, drinking water, food
industry, lacquer raw materials, many alkalide solutions and acids
(except concentrated nitric acid and hydrofluoric acid; ref. to "media
resistance"), also high-purity products (such as vitamins e.g.)
