2K polyvalent epoxy system. The system can be composed of a resin with relevant hardener or alternatively, combined with additives for the Epoblok System: microspheres, microfibres, thickening additive, phenolic microspheres. This system can satisfy different needs such as gluing, wood impregnation, fibreglass repair, osmosis prevention and refitting, caulking of different substrates, etc. It is therefore a highly multipurpose system for boat protection and refitting.
