We are giving you an overview of the most frequent chemical influences that may occur in common applications. Please, consider that the materials are exposed to different chemical influences and no material is resistant to all of them.

Please, also take into consideration:

In the table only raw chemical materials are listed. Different components of the luminaire are made from different materials.
The saturation level and / or percentage strength of the chemical substances
It is assumed that the ambient temperature does not exceed 25 °C. When exposed to different ambient temperatures, chemical reactions can vary.
The operators need to specify the specific chemicals to which the luminaire will be exposed in the application.

Cleaning

Avoid high-pressure cleaning processes. Use only cleaning agents appropriate for the component materials.
