Covalent Bonding of Silicone RTV Coatings

Covalent Bonding of Silicone RTV Coatings
Available for download

Silicone room temperature vulcanizing (RTV) polymer based coatings were designed with maintenance, and extending asset design life in mind. This technology can be tailored to be used as the backbone for a wide variety of coating applications by taking advantage of the inherent properties of RTV silicone.

Silicone room temperature vulcanizing (RTV) polymer based coatings were designed with maintenance, and extending asset design life in mind. This technology can be tailored to be used as the backbone for a wide variety of coating applications by taking advantage of the inherent properties of RTV silicone. Demands on protective coatings to meet longer service life have led to the devolvement of RTV silicone maintenance coatings. Historically, in the absence of commercially available polysiloxane RTV polymer coatings the comprehensive set of standards for accelerated performance indication have been tailored to evaluating either epoxy or polyurethane coatings. Considering this, a combination of accelerated laboratory testing, natural exposure testing and historical installations have been used to innovate technology that will push the performance limits of today’s silicone maintenance coatings. The basic philosophy behind the development of silicone polymer based coatings as an anticorrosion coating was to minimize the need for surface preparation by using covalent bonding rather than mechanical adhesion. As a result, silicone polymer based coatings have been developed to have superior adhesive properties, as they become one with the coated surface and do not simply sit on top providing a barrier. When compared to conventional coatings the surface tolerance created by this chemical bond eliminates the need for sandblasting and/or profiling of the substrate. For efficiency this allows specifying SP-1 or 2, where SP-6, 7, or 10 may have been previously required

CP Shielding and Pipeline Coatings

Product Number: 41206-285-SG
Author: Greg Ruschau
Publication Date: 2006
$20.00

Shielding of cathodic protection (CP) by pipeline coatings poses a serious threat to pipeline integrity.  The difficulty in pipeline coating selection to avoid shielding is that the same properties that make a pipeline coating a good corrosion mitigation material can also lead to CP shielding. The key to proper coating selection is to select a coating that has the necessary properties to provide good corrosion protection but also one that, when disbondment and failure occurs, fails in such a way to allow effective cathodic protection.

Data Management for Coating Inspection Gauges

Product Number: 41207-330-SG
Author: John Fletcher
Publication Date: 2007
$20.00

Many modern electronic gauges have the capability for transmitting or uploading data to a computer via a data port. This can mean transferring the data to a spreadsheet for customized analysis or to a data management software package for analysis using standard statistical methods. This paper describes the format of the data for a range of gauges used for the coating inspection process including surface profile determination, climatic condition monitoring and coating thickness measurement.
