HALOX® 515 LFG is a low-freeze-grade liquid organic corrosion inhibitor suitable for high-gloss (direct-to-metal) coating systems. When used as recommended, HALOX® 515 LFG provides cost-effective flash rust protection and long-term corrosion protection. It is effective for thin film applications (<2 mils). HALOX® 515 LFG is heavy metal-free, nitrite-free, and does not contain chromates or phosphates. Testing with HALOX® 515 LFG has shown improved adhesion at the scribe and good humidity resistance. Additionally, it has been proven effective as a flash rust inhibitor on weld seams.
