Title (EN) APPLICATION OF AN AQUEOUS DISPERSION OF POLYBUTADIENE WITH A VIEW TO FORMING AN INTERMEDIATE LAYER CONFERING THE ADHESION DURING THE PREPARATION OF POLYAMIDIC COATING ACCORDING TO THE SOCALLED COATING BY FUSION PROCESS
(FR) APPLICATION D"UNE DISPERSION AQUEUSE DE POLYBUTADIENE EN VUE DE FORMER UNE COUCHE INTERMEDIAIRE CONFERANT L"ADHESION LORS DE LA PREPARATION DE REVETEMENTS POLYAMIDIQUES SELON LE PROCEDE DIT DE REVETEMENT PAR FUSION
Abstract:
(EN) In the processes allowing to coat metal objects with polyamide coatings by the so-called fusion method an aqueous dispersion of polybutadiene is used according to the invention as an intermediate layer conferring the adhesion. This dispersion contains on one hand liquid polybutadiene having a dynamic viscosity of 70 to 30.000 m Pa s; the polybutadiene having the following ratios with regards to the repetitive units: 40 to 95% of cis-1.4 units and 0 to 30% of trans-1.4 units, as well as 1 to 60% of 1.2 units; on the other hand the dispersion contains 0.5 to 10% by weight (added to the polybutadiene) of an emulsifier.
(FR) Dans les procedes permettant de revetir des objets metalliques d"enduits polyamidiques par la methode de fusion l"on utilise selon l"invention, en tant que couche intermediaire conferant l"adhesion, une dispersion aqueuse de polybutadiene. Cette dispersion contient d"une part du polybutadiene liquide presentant une viscosite dynamique de 70 a 30.000 m Pa s; le polybutadiene presentant les taux suivants en ce qui concerne les unites repetitives: 40 a 95% d"unites cis-1.4 et 0 a 30% d"unites trans-1.4, ainsi que 1 a 60% d"unites 1.2; la dispersion contient d"autre part de 0.5% a 10% en poids (rapporte au polybutadiene) d"un emulsifiant.
