A two component paint composition that, after mixing, comprises the following components in aqueous solution: a) from the first component: i) an aqueous binder, which aqueous binder comprises an oligomeric or polymeric compound the oligomeric or polymeric compound being formed from at least one monomer of the general formula I: Si(OR)where each Ris independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, aryl or &#x2014;(C&#x2550;(O)Rgroup, and each Rgroup is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl or aryl group, and at least one monomer having the general formula II: (R)Si(OR)where each Ris independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl or aryl group, and wherein at least one &#x2014;Rgroup comprises the group &#x2014;RRor &#x2014;RN(R)where Ris any Cto Cbivalent organic bridging group, Q is selected from an Oxygen or a Sulphur radical and Rcomprises an H, alkyl, alkenyl, alkynyl, aralkyl or aryl group, and each Ris independently selected and defined as for Rabove; where each Ris independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, aryl or &#x2014;(C&#x2550;O)Rgroup, where Ris defined as for Rabove, and m=1 to 3; and, optionally at least one colloidal silica; b) from the second component i) at least one reactive filler material.

Paint composition

The present invention provides a process for the preparation of poly(silyl ester)s comprising a structural unit of the formula (I) wherein the process comprises the step of reacting a polyacid of formula (II) with a polyacyloxysilyl derivative of formula (III) while removing the formed acid group(s) of formula RZ(O)OH (IV). RZ(O)OH (V), and RZ(O)OH (VI) from the system.

Process for the preparation of poly(silyl ester)s, and their uses

The present invention relates to polyorganosilylated carboxylate monomers or polymers thereof, comprising a polyorganosilylated carboxylate monomer of the general formula (I) or a polymer thereof,  The invention also relates to the use of these monomers or polymers as coating compositions including antifouling coating compositions.

Process for the preparation of polyorganosilylated carboxylate monomers or polymers thereof

The present invention relates to a process for the preparation of polyorganosilylated carboxylate monomers or polymers thereof, comprising the steps of reacting a cyclosiloxane of formula (R4R5SiO)n with an unsaturated organosilylated carboxylate monomer or a copolymer or a polymer thereof under the presence of a suitable catalyst.

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.

Process for the preparation of organosilylated carboxylate monomers, and their use in antifouling coatings

The invention relates to new and known compounds as well as methods for preventing the attachment of aquatic organisms to surfaces which are submerged for extensive periods of time in water. More particularly, this invention relates to the protection of submerged surfaces with new isonitrile, formamide, isocyanate and isothiocyanate anti-fouling agents.

Rosin amine anti-fouling agents

The invention relates to methods for preventing the attachment of aquatic organisms to surfaces that are submerged for extension periods of time in water. More particularly, this invention relates to the protection of submerged surfaces with alkylamine derivatives as antifouling agents. The invention is beneficiary for the environment in that it will permit the use of copper- and tin-free paints.
