The invention relates to a molding, coloring and/or sealing compound, to a method for producing a molding, coloring and/or sealing compound and to useful layers consisting of said compounds. The invention provides molding, coloring and/or sealing compounds which allow the production of useful layers, protective layers, composite bodies or the like which have an extremely high and reliable water impermeability. This high water impermeability is achieved in that air inclusions in the compound are avoided.

The present invention is directed to a method of producing an adherent coating over untreated thermoplastic and thermosetting resinous substrates from a coating composition that includes a crosslinkable component and a crosslinking component that are mixed prior to application and applied over the substrate. The crosslinkable component includes a polymeric mix containing at least one crosslinkable copolymer polymerized from a monomer mixture comprising one or more ethylenically unsaturated monomers having on average 1 to 10, preferably 1 to 4 and more preferably 1 to 2 hydroxyl groups and a saturated hydrocarbon polymer. The crosslinkable component includes one or more cycloaliphatic polyisocyanate of the formula: R1(R2-NCO)n wherein R1 is a substituted or unsubstituted cycloaliphatic group, R2 is independently selected from a direct bond, a straight aliphatic group or branched aliphatic group, and wherein n ranges from 2 to 10. The method is well suited to produce adherent coatings on olefinic substrates such as those used in automotive and general commercial application without any pretreatment of the resinous substrates.

The present invention provides a primer composition comprising
(A) a vinyl polymer having a main chain substantially comprising vinyl copolymer chain and at least one silicon-containing group having a hydroxy group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond at the terminal end of the main chain and/or side chain, and (B) (a) a saturated hydrocarbon polymer having at least one silicon-containing group having a hydroxy group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond, and/or (b) a polybutadiene polymer having at least one silicon containing group having a hydroxy group or a hydrolyzable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond, which can remarkably improve the adhesion to various kinds of substrates, and which is particularly useful when applied to the isobutylene series sealing material.
摘要:
L'invention concerne des fibres revêtues d'une matière hydrophobe à base d'un oligomère de polydiène époxydé. Ce revêtement résulte de la photopolymérisation d'une composition comprenant au moins un oligomère de polydiène époxydé, au moins un sel photoamorceur et éventuellement un diluant réactif. L'invention concerne particulièrement les fibres optiques.
