UV Coating Technology Is Suitable For High Performance Industrial Applications

Requiring Corrosion Protection

• Improved Protection Of Steel Compared To Standard Coatings

• Dramatically Faster Cure With Lower Material Usage

• Can Be Multifunctional Coating Or Primer/Topcoat System

• Elimination Of Solvents, VOCs, HAPs, Isocyanates, Chromates

• Reduced Pollution And Improved Health Considerations

• Safer And More Efficient Alternative For Corrosion Protection

UV Coating Technology Is Suitable For Corrosion Protection Of Large Structures

• Just As Any Surface Can Be Painted By A Few Individuals Spraying Or Rolling, A UV Coating Can Be Applied And Cured By Painting And Then Following With A UV Lamp

• Cure Is Achieved With A Motion That Can Be Described As "Painting" The Surface With A Handheld UV Lamp

• Movement Of The UV Lamp Is Similar To That Of A Roller Or Spray Gun - At The Same Speed As Paint Application

UV Coating Technology Is Suitable For Corrosion Protection Of Large Structures

UV Technology Is Suitable For Cold Temperatures

• UV Cure Is Tolerant Of Adverse Conditions (34°F)

• Maintains Fast Cure In Seconds

UV Technology Is Suitable For A Wider Range Of Application Conditions Than Standard Coatings

• When Compared To Conventional Paints, UV Cure Is Relatively Independent Of Temperature And Humidity

• UV Coatings Cured Completely In Seconds With Good Performance In A Field Application At 34°F - No Standard Paint Would Have Cured Under Those Conditions

• Good Cure Performance Has Also Been Demonstrated Under Typical Ambient Summertime Conditions

UV Technology Is Suitable For Aerospace Applications Requiring Corrosion Resistance
