Denso Hi-Tack Tape is composed of a non-woven synthetic fabric impregnated and coated with an adhesive compound based on petrolatum, polymers and inert siliceous fillers.

A specially developed tape to protect structural steel and other overhead surfaces. Adhesion properties create a "wallpaper" type application. Adhesion qualities are significantly higher compared to other Denso Petrolatum Tapes.

• Applied to marginally prepared surfaces (SSPC SP 2-3)
• High conformability with strong adhesion
• Encapsulate lead paint
• Can reduce or eliminate plant shut-down for maintenance
• Long term cost effective corrosion protection
• Instant and uniform protection given irrespective of the profile
• Resistant to acids, alkalis, salts etc.
• Elimination of failure due to intercoat contamination
• Years of proven effectiveness

Prepare surfaces by removing all loose scale, rust or other foreign matter in accordance to SSPC SP2 "Hand Tool Cleaning" or SP3 "Power Tool Cleaning". High pressure water wash of 3,000 - 7,000 psi is also suitable. Apply a thin film of Denso Hi-Tack Primer to serve as a primer. For structural members choose tape width that allow 1" overlap in a downward direction. Do not overlap on the underside of horizontal surfaces. Do not attempt to work with lengths greater than 6 feet. Where possible overlap from bottom upward to create a "shingle" type overlap.

Press and smooth with special attention to overlap areas. Make sure tape is firmly pressed in all angles and corners and then along flat surfaces to prevent air pockets, bridging, or stretching. Goal is to ensure intimate contact between tape and surface.

Rivets, nuts, bolts may be rounded with Densyl Mastic, Denso Profiling Mastic or the use of a second layer of Denso Hi-Tack Tape for these areas only.
