CUI Coatings

Coatings for CUI Prevention

Highland’s CUI coatings have raised the bar in the prevention of Corrosion Under Insulation (CUI) service category. A combination of high build barrier properties and extremely dense cross linking isolate the substrate from moisture and corrosion. In addition, the chemistry behind these coatings is second to none. Our CUI coatings are the product of extensive research and development. These efforts have resulted in fantastic performance and service life.  Our CUI coatings can withstand extreme temperatures ranging from -300°F to 1200°F.  Furthermore, they offer superior resistance to boiling water  and thermal shock. Additionally, our CUI coatings can be applied directly to hot steel surfaces up to 750°F. All of this adds up to easier applications, and maximum service life even in the harshest environments. Check out our High Temp Paint page for heat resistant coating options for all areas of your facility.

Preventing CUI with a Thermal Insulating Coating

It is time to replace your traditional insulation with Highland 350-INS thermal insulating coating. Making the switch from traditional insulation to our thermal insulating coating is easier than you may think. In addition to the insulating benefits, 350-INS adds another layer of protection from corrosion under insulation. Traditional insulation is easily damaged, and can trap water against the surface. Trapped water creates an extremely harsh environment which will degrade steel very quickly. 350-INS does not allow water to permeate to the surface. Furthermore, 350-INS serves multiple purposes: it insulates, it lowers surface temperatures, and it seals the surface off from corrosion.

Dry Fall Coatings for Corrosion Under Insulation

Highland CUI coatings don’t stop at fantastic performance. Many of them feature dry fall capabilities. When using our dry fall CUI coatings, all overspray is dry to a powder within 20 feet of the application site. This unique feature allows for spray applications with no risk of overspray damage.  Highland is the only manufacturer of dry fall CUI coatings.
