PATTM-wetting agents already reduce the surface tension of resin solutions at very low dosage levels. Thus, the resin penetration into the impregnated paper is improved, more consistent, & a smooth and even surface film is produced.
In combination with PATTM-catalysts, PATTM-release agents and an eventually modified resin a perfectly closed laminate-surface with high gloss can be created.
PATTM-wetting agents are environmentally friendly, low foaming, transparent liquids, which do not disintegrate during normal laminating temperatures. Color variations and surface blemishes will not occur during lamination.
By using internal PATTM-release agents even at low temperatures and short pressing cycles (less than 10 sec, for instance), a contamination of press plates is avoided and a closed laminate-surface is achieved. Hence, there is no need to use external release agents.
By removing resin and pigment residues constantly from the press plates, PATTM-release agents also show a cleaning effect (results vary from grade to grade). Thus, for instance during CPL production (Continuous Process Lamination), there is minimal accumulation of residue on the press over long periods of time so that high quality laminates can be produced continuously without problems.
When using internal PATTM-release agents, you will be able to achieve shorter cycle times.
We offer internal PATTM-release agents for UF, MF, MUF, PF and MUPF resin systems for various application areas: A wide choice of environmentally friendly products is available for your needs!
For impregnation resins used in overlay and decorative paper, we offer a comprehensive selection of direct and latent PATTM-catalysts for UF, MF and MUF resins for LPL, HPL and CPL processes. All catalysts show a high efficiency, leading to a reduced overall consumption.
