olysilazanes are an entirely new class of coating binders, an advancement in silicon polymer technology that is proprietary to Merck. Their polymer backbone consists of alternating silicon and nitrogen atoms. Owing to their unique properties, they are the perfect choice for ultimate protection in many high-value applications. Two different product groups are available: organic polysilazanes (OPSZ) marketed under the brand name Durazane®, and inorganic polysilazanes, also known as perhydropolysilazanes (PHPS). Polysilazanes offer multifunctional surface protection featuring high-temperature resistance, water/ dirt repellency, and protection against scratches, weathering and corrosion (ref. Opening photo).

polisilazani sono un’innovativa classe di leganti funzionali per rivestimenti, un passo avanti nella tecnologia dei polimeri di silicio, di proprietà di Merck. Costituiti sostanzialmente da un’alternanza di atomi di silicio ed azoto, grazie alle loro proprietà uniche, rappresentano la scelta perfetta per ottenere la massima protezione e per garantire alte prestazioni in molteplici applicazioni. Sono disponibili sia in forma organica (OPSZ), con la gamma Durazane®, sia in forma inorganica (PHPS), noti anche come peridropolisilazani. I polisilazani offrono una protezione della superficie multifunzionale con resistenza alle alte temperature, repellenza ad acqua e sporco, protezione da graffi, agenti atmosferici e corrosione (rif. foto d’apertura).

When we think of corrosion, those who are not acquainted with the theory and practice of metallurgy tend to think that it occurs only in surface weather conditions and on outdoor objects and structures. Insiders, however, know perfectly well that this is not the case: corrosion attacks metal substrates whether they are installed on the earth’s surface or beneath it, buried or submerged. And things become even more complicated if these assets are located on the surface, but offshore. This issue of ipcm_Protective Coatings, which inaugurates our seventh year of publication, presents an unprecedentedly wide variety of articles dealing with research, development, and innovative products engineered to effectively meet the specific needs of an industry.
