Epoxy resin composition curing agents, which include a primary amino alcohol, are disclosed. Specifically, the invention relates to curing agents which include a primary amino alcohol physically blended therewith. Alternatively, the invention relates to curing agents which include a primary amino alcohol reacted into a resinous phenolic compound. Resin systems utilizing the curing agents of the invention exhibit enhanced hot wet adhesion to metal substrates and are particularly useful in the manufacture of powder coatings for pipe.
L'invention concerne des agents de durcissement de compositions de résines époxy, comprenant un amino-alcool primaire. L'invention concerne spécifiquement des agents de durcissement comprenant un amino-alcool primaire physiquement mélangé avec. Selon un autre mode de réalisation, l'invention concerne des agents de durcissement comprenant un amino-alcool primaire mis à réagir pour donner lieu à un composé phénolique résineux. Des systèmes de résine faisant appel aux agents de durcissement de l'invention présentent une adhérence renforcée à l'état humide à chaud, aux substrats métalliques, et s'utilisent notamment dans la production de revêtements pulvérulents pour tuyaux.
