Hydrocarbons, ketones and freon do not affect
the overlay. But, we recommend that you do not
subject the keyboard to these chemicals, since
they may affect the switch housing, which is
ABS plastic. To discuss a particular solvent,
contact Grayhill.
The contact system is internally sealed by a
special adhesive backed sheet that holds the
domes in position on the PC board.
