Previous research showed polysiloxanes as a potential replacement.  This research studied 12 polysiloxane coating systems that were formulated for improved erosion and impact resistance. Laboratory results showed that 3-D-P-2K-2-S is considered a valid replacement for vinyl system 4. Although system, 3-Z-P-2K-2-S had blistering and adhesion issues, it might be possible for the manufacturer to find a different zinc rich primer to get the desired performance, and potentially be a replacement for vinyl system 5EZ. None of the coating systems from manufacturers one or two are viable replacements for either of the vinyl coating systems.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://data.usbr.gov/catalog/8048/item/128745", "description": "Landing page for \"S&T Project 21019 Final Report: Investigating Newly Formulated Polysiloxane Coating Systems with Improved Erosion and Impact Properties\"", "mediaType": "text/html", "title": "RISE Item Details Page URL for \"S&T Project 21019 Final Report: Investigating Newly Formulated Polysiloxane Coating Systems with Improved Erosion and Impact Properties\""}, {"@type": "dcat:Distribution", "description": "\"S&T Project 21019 Final Report: Investigating Newly Formulated Polysiloxane Coating Systems with Improved Erosion and Impact Properties\" as a PDF file", "downloadURL": "https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/Investigating%20Newly%20Formulated%20Polysiloxane%20Coating%20Systems%20with%20Improved%20Erosion%20and%20Impact%20Properties%20Final%20Report_508.pdf", "mediaType": "application/pdf", "title": "PDF File for \"S&T Project 21019 Final Report: Investigating Newly Formulated Polysiloxane Coating Systems with Improved Erosion and Impact Properties\""}], "identifier": "https://datainventory.usbr.gov/rise/item/128745", "keyword": ["Corrosion Protection", "Polysiloxanes", "Protective Coatings"], "landingPage": "https://data.usbr.gov/catalog/8048/item/128745", "modified": "2024-09-30T11:54:04Z", "publisher": {"@type": "org:Organization", "name": "Bureau of Reclamation"}, "spatial": "{\"type\":\"Polygon\",\"coordinates\":[[[-105.12484,39.72238],[-105.1217,39.72366],[-105.1199,39.72123],[-105.12164,39.72052],[-105.12285,39.72213],[-105.12431,39.72153],[-105.12484,39.72238]]]}", "title": "S&T Project 21019 Final Report: Investigating Newly Formulated Polysiloxane Coating Systems with Improved Erosion and Impact Properties"}
