1 VITS SYSTEMS GmbH Basic Impregnation Technology VITS Systems GmbH Impregnation Lines For Laminate Products Part 1 The Melamine Paper Impregnating Process

2 VITS SYSTEMS GmbH Basic Impregnation Technology What Is Impregnation ? Impregnation is the saturation of a basic substrate Examples of impregnation are: Fibre Glass Mat Impregnated with Epoxy Resin for the printed circuit boards Woven Cloth for reinforced fabric Paper for Car Filter elements Woven Nylon for weather protective clothing Decorative and Kraft Paper for the Laminates Industry

3 VITS SYSTEMS GmbH Basic Impregnation Technology Why Paper ? Readily available in roll formReadily available in roll form Fibrous structureFibrous structure Can be easily impregnatedCan be easily impregnated Available in different widths and strengthsAvailable in different widths and strengths Can be produced in various different colours as a raw materialCan be produced in various different colours as a raw material Can be printed into high quality décorsCan be printed into high quality décors

4 VITS SYSTEMS GmbH Basic Impregnation Technology Difference Between Impregnating and Coating Coating: Impregnation: Medium is applied to the outside surface of the substrate Avoids coating medium seeping into the core of the substrate Medium is applied to the inside or core of the substrate

5 VITS SYSTEMS GmbH Basic Impregnation Technology The Impregnation Process Success of Final Pressed Product Depends on: Raw material to Impregnation Line Impregnation Machines Impregnating Process parameters Intermediate Products Press and its Raw materials (Board) Press Process Parameters Many Different Influences on Final Product Quality ! Where the raw materials are brought together
