CorroLogic® CUI Inhibitor

Product Description

CorroLogic®CUI Inhibitor is a solvent-based, injectable corrosion inhibitor for protection against corrosion under insulation (CUI). CorroLogic® CUI Inhibitor combats corrosion caused by moisture and other corrosive media that enter insulation after water barrier wraps or jackets are compromised or when condensation builds up beneath the insulation. Moisture trapped between insulation and metal surfaces, such as piping, encourages corrosion that may go undetected for long periods of time. This can cause serious maintenance and repair costs and potentially dangerous leaks. 

Applying CorroLogic® CUI Inhibitor provides long-lasting benefits such as decreased maintenance costs, reduced downtime for repair and replacement, and an overall increase in safety by preventing catastrophic failures related to corrosion. Vapor phase Corrosion Inhibitors in the product enable CorroLogic® CUI Inhibitor to be injected into existing insulation and allowed to migrate through the insulation to protect metal surfaces below.

Packaging and Storage

CorroLogic ® CUI Inhibitor is available in 5 gallon (19 L) plastic pails, 55 gallon (208 L) metal drums, liquid totes, and bulk.

To ensure best product performance, store in original packaging, indoors, and out of direct sunlight at 40-100 °F (4-38 °C).

Shelf life: 2 years

Features

• Vapor phase Corrosion Inhibitors migrate throughout insulation to protect insulated metal surfaces from corrosion  
• Protects in wet and dry cycles  
• Long lasting

Benefits

• Inhibits CUI on pipes and other insulated metal surfaces  
• Reduces frequency of maintenance and repair related to CUI  
• Increases overall plant safety by reducing dangerous corrosion-related failures

Application

CorroLogic® CUI Inhibitor should be injected beneath the existing insulation at a rate of 0.3 fluid ounces per cubic foot (0.3 liters per cubic meter) of insulation volume. Injection points should be spaced every 10-20 feet (3-6 meters) to allow proper dispersion and application of the product. Do not use on pipes that will exceed 338 °F (170 °C).
