  • Screen Compatibility with Metal Cutting Coolant

    I would like to know if the screen is compatible with a metal cutting coolant called Chem Kut 5005. Below is the spec sheet on it. The coolant is a water based coolant. If the actual data sheet is needed Message me and I can email it.


    Substance / Mixture:

    Components/Ingredients CAS No. % Range*
    Distillates (petroleum), hydrotreated heavy naphthenic 64742-52-5 <30
    2-amino-2-methylpropanol 124-68-5 <5
    2-aminoethanol 141-43-5 <5
    2,2,2-nitrilotriethanol 102-71-6 <5
    *Specific percentages of composition are being withheld as a trade secret.
    *Proprietary CAS numbers are being withheld as a trade secret.
    Additional components, of which may or may not be present, in this mixture are not classified as hazardous to health or the
    environment and within the current knowledge of the manufacturer or supplier and current regulations, are required to be
    reported in this section.

    I guess I should state that I am wanting to use either the latest C-More or C-More Micro......

      From the C-more EA9 manual: https://cdn.automationdirect.com/sta...9userm/ch2.pdf

      Chemical Compatibility
      The C-more touch panels comprise three different materials that may be exposed to outside elements: a gasket, a screen sheet and a bezel.
      • Gasket material is silicone.
      • Screen sheets are PET.
      • Panel bezels are ABS plastic.

      It is really up to the user to determine the chemical compatibility from this information since the manufacturer cannot anticipate all possible exposures.

      In my experience, Ethanol and ABS do not get along well. ABS becomes brittle and falls apart. I am no chemist, but I see several components that have ethanol in their name.

      I recommend you contact the chemical provider and ask them about their compatibility with the three components above, Silicone, PET and ABS.
