2-component, colorless, transparent primer. It consists of a hardener mixture and an epoxy resin with special additives. In every set, there are two packages weighed at the factory. It is used to increase the adhesion strength of the system by reducing the suction of the surfaces under the base paint and coatings. It is used in water insulations, for filling cracks in concrete and stones, in carbon fiber lamination
