Organic and inorganic polysilazanes - a novel class of high-performance coating binders

 
Achieving a coating that performs well also in demanding environments is a challenging task. Polysilazanes are a new generation of silicon polymers consisting of alternating silicon and nitrogen atoms that are able to fulfil this promise. Polysilazanes enable a real ceramic coating that can withstand high temperatures (up to 1000 °C), provide a high scratch (up to 9H) and weathering resistance and excel at corrosion protection. This has allowed for a considerable success in applications around automotive, architectural and industrial coatings. They provide ultimate protection with good adhesion and durability of all kinds of substrate surfaces like metals, glass, plastics, composites or wood. Polysilazanes are low-viscosity, water-like polymers as solvent-containing or solvent-free products that can be cured employing either heat, moisture or UV-radiation.
