Resistance to oil and chemicals
ǠDIN EN ISO 175
Physical and/or chemical processes/reactions
can occur as a result of external media,
such as liquids or gases. This can result
in a change to the plastic's properties,
the plastic becoming damaged or even
destroyed. The printings and labelings can
also be affected by these changes.

Resistance to solvents
ǠEN 60464-2:2001
Phoenix Contact marking materials are
solvent-resistant and fulfill the stringent
requirements.
Printings and labelings must be resistant to
solvent vapors. Therefore, in accordance
with the aforementioned standard,
exposure to solvents is continued over
10 days in the following atmospheres:
• Acetone
• n-hexane
• Ethanol
The labelings and printings must still be
legible after the 10-day exposure.
