Reco-Cool OAT-10XSC is a super concentrate water-based corrosion inhibitor for engine cooling systems. It uses organic acid technology (OAT) and is free from amines, borates, nitrates, nitrites, phosphates, and silicates. This product must be diluted before use, following Recochem’s guidelines (typically 7% m/m in solution). It should be mixed with demineralized water or a blend of demineralized water and MEG for better freezing protection. All blending must follow Recochem’s approved processes to ensure quality.
