Zusammenfassung: | Use of a composition comprising a polymeric system implemented in a methacrylate matrix for caulking, preferably bridge and/or ship hull, is claimed, where: the polymeric system contains block copolymers (such as A, B, C, etc block copolymers) without styrene forming at least two blocks, preferably three blocks and is dissolved in a matrix of aromatic linear or branched acrylic and/or methacrylic monomers; and the matrix is included or intended to be included in a structural type methacrylate adhesive formulation. An independent claim is included for caulking of wood and/or bridge of ship comprising degreasing wood caulk and/or deck of the ship, applying the adhesive composition and accosting the teak deck, filling grooves with the composition and applying the resin to a slight dome to allow it to compensate the post cross linking shrinkage, cross linking the applied composition, and grinding the excess caulking/binding composition of joint surfaces to be applied and cured, after a duration of not more than 2-4 hours.
Utilisation pour le calfatage, notamment de pont et/ou de coque de navires, d'une composition comportant essentiellement un système polymérique apte à être mis en oeuvre dans une matrice de méthacrylate, ledit système polymérique comprenant des copolymères séquencés (encore dénommés copolymères à blocs) sans styrène, formés d'au moins deux blocs et de préférence d'au moins trois blocs, et ledit système polymérique étant solubilisé dans une matrice de monomères acryliques et/ou méthacryliques, linéaires ou ramifiés, et/ ou de méthacrylates aromatiques, tandis que ladite matrice est incluse ou destinée à être incluse dans une formulation d'adhésifs structuraux de type méthacrylate. Procédé de calfatage de bois et/ ou d'un pont de navire utilisant une telle composition |
