Beschreibung
Zusammenfassung:	Provided herein are novel and improved weight coating systems suitable for use with pipes, particularly pipes that are submerged in liquid, such as water, in environments including oceans, seas, marshes, lakes and rivers. The novel coating systems provided herein comprise an aggregate and a polyurethane binder, wherein the polyurethane binder is a two-component composition comprising an isocyanate component and an isocyanate-reactive component. The coating systems provided have increased durability, as well as flexibility allowing for efficiencies related to transportation, storage, use and resistance to corrosive effects. Furthermore, the coating systems are cost effective and have minimal or zero impact on the environments in which they are utilized. L'invention concerne de nouveaux systèmes de revêtement de lestage améliorés, appropriés pour être utilisés avec des tuyaux, en particulier des tuyaux qui sont submergés dans un liquide, tel que de l'eau, dans des environnements comprenant les océans, les mers, les marais, les lacs et les rivières. Les nouveaux systèmes de revêtement de l'invention comprennent un agrégat et un liant de polyuréthane, le liant de polyuréthane étant une composition à deux constituants comprenant un constituant isocyanate et un constituant réactif avec l'isocyanate. Les systèmes de revêtement selon l'invention présentent une durabilité accrue, ainsi qu'une souplesse permettant des gains liés au transport, au stockage, à l'utilisation et à la résistance à des effets corrosifs. En outre, les systèmes de revêtement sont rentables et présentent un impact minimal ou nul sur les environnements dans lesquels ils sont utilisés.
