It is not a paint or primer. OSPHO-16 reacts chemically with iron oxide (rust), converting it to iron phosphate — an inert, hard compound that bonds to the metal and turns it black. The treatment is suitable for ferrous metals and aluminum, works on both exterior and interior surfaces, and covers approximately 600 square feet per gallon. Installers and maintenance technicians apply it prior to oil-base primers and topcoats to extend coating life and prevent corrosion recurrence.\u003c\/p\u003e\n\u003cp\u003eOSPHO-16 is used across a wide range of trade applications where metal surfaces are subject to rust and corrosion: structural steel, HVAC equipment frames, ductwork supports, plumbing hangers, pool equipment enclosures, electrical conduit supports, and similar ferrous components. It is equally effective on new metal to prevent initial oxidation and on corroded surfaces to stabilize existing rust before coating. The product requires overnight drying before topcoating under standard conditions. When used under epoxy or latex-base coatings, test a small area first to confirm adhesion compatibility.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConverts iron oxide (rust) to iron phosphate — a hard, inert, tightly bonded surface compound\u003c\/li\u003e\n  \u003cli\u003eSuitable for both new and corroded ferrous metals and aluminum\u003c\/li\u003e\n  \u003cli\u003eEffective for interior and exterior applications\u003c\/li\u003e\n  \u003cli\u003eCoverage rate of approximately 600 square feet per gallon\u003c\/li\u003e\n  \u003cli\u003eRecommended for use under oil-base primers and paints; test before use under epoxy or latex\u003c\/li\u003e\n  \u003cli\u003eContains phosphoric acid as the active chemical agent\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on ferrous metals and aluminum surfaces as a pre-coating rust inhibiting treatment.

Ensure adequate ventilation in confined spaces before applying; phosphoric acid vapors require respiratory and eye protection, and chemical-resistant gloves should be worn throughout. Allow the treated surface to dry overnight before applying any topcoat. Keep product out of reach of children and store according to applicable safety data sheet guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActive Ingredient\u003c\/strong\u003e: Phosphoric acid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoverage\u003c\/strong\u003e: Approximately 600 square feet per gallon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 1 gallon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.525 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDry Time Before Topcoat\u003c\/strong\u003e: Overnight (standard conditions)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuitable Substrates\u003c\/strong\u003e: Ferrous metals, aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication Environment\u003c\/strong\u003e: Interior and exterior\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00757533012757\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SKYCO CHEMICALS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: OSPHO-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SKYCO CHEMICALS","offers":[{"title":"Default Title","offer_id":51345278501170,"sku":"OSPHO-16","price":155.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551517.jpg?v=1782053781","url":"https:\/\/voomisupply.com\/products\/skyco-chemicals-ospho-16-rust-inhibiting-treatment-1-gallon","provider":"Voomi Supply","version":"1.0","type":"link"}
