Dosing systems for the surface protection of composite materials

Since composite components are exposed to extreme environmental influences, e.g. through their use in automotive and aircraft construction, appropriate surface protection is necessary. This is either applied to the composite material as a gel coat or applied beforehand as an In-Mould Gelcoat. This means that the surface protection is applied in the mould, e.g. before the Infusion or RTM process.

DOPAG developed the metering and mixing system gelcomix for Gelcoat applications in rotor blade production. It is used to prepare the two-component material, an epoxy resin or polyurethane, and then manually applied to the mould surface.
