Abstract: A process for the production of hydrocarbyl silyl unsaturated carboxylates of formula (I) is described, wherein n represents a number of dihydrocarbylsiloxane units from 0 to 1000. The process includes the reaction of an unsaturated carboxylic acid of formula (II) with a hydrocarbyl silyl compound of formula (III) the said reaction being carried out in the presence of a silaphilic catalyst.

Abstract: Process for the preparation of organosilylated carboxylate monomers comprising the step of reacting an acyloxysilane with an unsaturated carboxylic acid, the monomers and their use as comonomer unit in the binder of antifouling coating compositions.

Abstract: A paint composition comprising silylesters of rosin. Silylesters of rosin are used in self-polishing antifouling paints alone or in combination with other binder components. A process is also defined for the addition of silylesters to paint compositions.

Abstract: Water-based protective coating compositions contain as binder the product obtained by the reaction of an aminosilane, in acid solution, with a sub-stoechiometric amount of an epoxysilane, and further contain finely divided zinc and dispersed pigments.

Abstract: The application relates to a method for preparing a pigment concentrate which is suitable, in particular, for the preparation of a powder coating. The pigment concentrate is prepared by pigment particles being comminuted in the presence of an aqueous binder essentially consisting of a polyester having a glass transition temperature of at least 60 ° C. and an acid value of at least 60, to form a stable paste or suspension, the said paste or suspension formed being subjected to a drying treatment, and the pigment concentrate being collected. The binder used is preferably free of cosolvent, while expediently it is a resin having an acid value of at least 70 ° C. Preferably, no dispersant is used. By using a pigment concentrate formed according to the present method, a powder coating can be formed which no longer has a tinting strength reserve.

Abstract: 2-trihalogenomethyl-3-halogeno-4-cyano pyrrole derivatives which are substituted in position 5 and optionally in position 1 are used as barnaclecide in antifouling paints, which can therefore be formulated as light- or bright-colored, particularly as bright white. The halogens in positions 2 and 3 are independently selected from the group consisting of florine, chlorine and bromine, preferably florine in position 2 and bromine in position 3. The substituent in position 5 is selected from the group consisting of C1-8 alkyl, C1-8 monohalogenoalkyl, C5-6 cycloalkyl, C5-6 monohalogenocycloalkyl, benzyl, phenyl, mono- and di-halogeno-benzyl or -phenyl, mono- and di-C1-4 alkyl benzyl or phenyl, and monohalogeno mono-C1-4-alkyl benzyl or phenyl, the halogen being selected from the group consisting of chlorine and bromine, prefereably chlorine; the most preferred substituent in position 5 is parachlorophenyl.

Abstract: Aqueous multiphase dispersions for multicolor coatings are produced by a process essentially comprising the steps of:providing one or more emulsion paints;adding at least one linear colloid capable of being insolubilised by borate ions and at least one hydrophilic inorganic clay to said paints to form base paints;providing an aqueous medium containing at least one hydrophilic inorganic clay;adding said base paints into said aqueous medium;adding borate ions to said aqueous medium;adding at least one emulsified binder to said medium;each of the emulsion paints having a different color.It is preferred to use galactomannoglycans as colloid (most preferably guar gum) and synthetic clays (most preferably of the smectite or hectorite types).
