Résumé : |
Polyurethane - One-pack polyurethane coatings have been used since the early 1970s, starting in the German coil coating industry. They have proven successful and versatile as primers, top coats, backing coats and as special adhesives. With their decorative, protective and other functional properties they have found a variety of use in the building construction, appliance and transportation markets. Occupational health and safety issues on handling during the preparation steps from a monomeric diisocyanate to a polyurethane coating are dealt with in detail. Today's paint lines using these polyurethane systems are very safe working environments. |
