Melamine Impregnated Paper :additives within the impregnation process
additives within the impregnation process
In order to effectively saturate the core of décor-paper and to coat its surface impregnation resins require several chemical additives and catalysts (hardener). Very important is the uniform distribution of the resins within and on the paper, which generally is achieved with wetting agents. Turbulences in the resin bath and on the coater often lead to foam generation. It is therefore very important that wetting agents are designed to prevent the formation of stable foams. The quality of the surface is enhanced through film forming additives that permit a smooth and bubble free drying process. Clean release of the cured paper laminate from the press without accumulation of residues on the press plates is essential for a cost efficient process. Specially designed release agents are thusly needed to minimize the need for long plate cleaning.
