Chemical Resistance of GRP

This table is for reference only and refers to a fully-cured resin without glass fibres lying on the surface. As far as specific concentrations are mentioned, they refer to solutions in water.

Caption
 + Good resistance at the mentioned temperatures.
 o After some time discoloration
or a light attack to the surface can occur.
Probably it is better to choose a different resin.
 – The resin is attacked and will be destroyed;
it is not suitable for the application.
