RELEST Wind ProcessCoat is a Solvent-free translucent 2K polyurethane for use as an in-mold gelcoat with low film thicknesses. Utilizing the new generation of UV absorbers allows for temporary outdoor storage of uncoated rotor blades, without the risk of UV light damaging the substrate. The product's great sandability facilitates the further treatment of demoulded rotor blades and forms an excellent, pore-free basis for subsequent coatings.
