A radio frequency signaling system includes a curable coating composition configured to be cured to form a cured coating and a sensor received in the curable coating composition. The sensor includes circuitry forming an inductor-capacitor circuit. The circuitry has a maximum outer diameter of 10 μm-2.0 mm. The circuitry is configured to generate an electromagnetic field in response to an external radio frequency signal. A container configured to be monitored by a radio frequency signaling system is also provided. The container includes: a container body having an outer surface and an inner surface; a cured coating on the inner surface and/or the outer surface of the container body; and a sensor positioned in the cured coating configured to detect absorption of a fluid contained in the container body by the cured coating.

Radio frequency signaling system and curable composition

An erodible antifouling coating composition for application, for example, to ship's hulls to potentially prevent the adhesion and build-up of fouling agents on the hull is described. The coating composition includes 10 to 60% by solids weight of an erodible binder system that excludes a triorgano tin based binder; one or more antifouling agents; and 1 to 10% solids weight of a mixture of silicone oils, wherein the mixture includes a first and second silicone oil each comprising alkyl and aryl groups attached to silicone in a different ratio. A process for producing the composition, a substrate coated with the composition, and a process of coating a substrate with the composition are also described.

Erodible antifouling coating composition

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.
