Di-isocyanates: everything you need to know about the new regulations
Di-isocyanates can have a major negative impact on the health of the user. That is why the European Commission has published the restriction under REACH for working with products containing more than 0.1% free di-isocyanate monomers. On 3 August 2020, the European Commission strengthened the restrictions under REACH to limit the use of Polyurethane coatings […]
Deck Coatings
The importance of On-Board Maintenance for Ships Maintenance of deck coatings on ships is important not only for protection the structures against corrosion but also for maintaining the appearance of the vessels and providing a safe environment for the passengers and crew. Many vessels are at sea much of the time, sometimes stopping only long […]
Introduction to Corrosion
Probably is the reaction of ordinary steel with its surroundings, where a voluminous, and porous coat of rust is formed, the most well-known example of what is called corrosion. There are many acquaintances examples from everyday life such as the rusting of garden trellises, steel structures, ships the rusting of bolts and nuts or exhausts […]

Moisture Curing One-Component Coatings
One of the most versatile functional groups from the paint chemistry is the Isocyanate group. R – N = C = O or R – NCO During the late 1930’s, Otto Bayer and his co-workers pioneered the chemistry of polyisocyanates, a technology which led to the advert of polyurethanes for a variety of […]
