Title (EN) A POLYSILOXANE HYDROPHOBIC COATING MATERIAL
(FR) MATÉRIAU DE POLYSILOXANE DE REVÊTEMENT HYDROPHOBE
Abstract:
(EN) The present invention relates to a hydrophobic coating material comprising a plurality of polysiloxanes cross-linked by a cross-linker having at least one unsaturated functional group, a process for preparing said coating, a coated article as well as a process for coating said article. The coating material is prepared by reacting the plurality of polysiloxanes with the cross-linker in the presence of a catalyst. In a preferred embodiment, the unsaturated group of the cross-linker is a vinyl, methacrylate or acrylate group, such as pentaerythitol tetramethacrylate. The coated article may be a fabric.
(FR) La présente invention concerne un matériau de revêtement hydrophobe comprenant une pluralité de polysiloxanes réticulés par un agent de réticulation présentant au moins un groupe fonctionnel insaturé, un procédé de préparation dudit revêtement, un article revêtu ainsi qu’un procédé de revêtement dudit article. Le matériau de revêtement est préparé par réaction de la pluralité de polysiloxanes avec l’agent de réticulation en la présence d’un catalyseur. Dans un mode de réalisation préféré, le groupe insaturé de l’agent de réticulation est un groupe vinyle, méthacrylate ou acrylate, tel que le tétraméthacrylate de pentaérythritol. L’article revêtu peut être un textile.
