The present application relates to a method for producing a laminate comprised of alternating smooth and corrugated sheets and which are to form a corrugated structure for the manufacture of contactors, characterized by that a first starting material is impregnated with a solution comprising water glass and additive whereas the additive is present at a high level and which is later corrugated and that a second starting material is impregnated with a solution comprising water glass and additive whereas the additive is present at a moderate level and that the both starting materials are brought together after the corrugation of the first starting material whereby the adhesion is maintained at a high level. The present application also relates to a laminate obtainable by said method and a contactor manufactured from a laminate obtainable by said method. |
