Protective coating with exceptional mechanical and impact strength for underwater, underground, and above-ground pipes and piles.
Description
Denso Glass Outerwrap is a fiberglass cloth impregnated with a water activated resin that is used as a protective outer wrap over Denso Petrolatum Tape. Also used as a pipe repair tape.
Uses
A protective fiberglass coating which offers exceptional mechanical and impact strength for underwater, underground, and above ground pipe and pipelines.
Features
Resists cold and hot temperatures
Easy to apply, no mixing or messy clean up
Resistant to water, acid, salts, or soil organics
Can be applied underwater or to wet surfaces
Minimal surface preparation required
Quick, long term protective coating, ready for immediate service
Contains no solvents
Application
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. Spirally wrap a layer of Denso Petrolatum Tape with a minimum 1" overlap. For severely corrosive environments, a 55% overlap is recommended. While wrapping, press air pockets out and smooth all lap seams. Using rubber gloves, remove the Denso Glass Outerwrap from the hermetically sealed foiled pouch and soak in temperate water (salt or fresh) for 20 to 30 seconds. Remove and begin wrapping tightly, overlapping a recommended 50%.
Irregular surfaces such as valves, flanges, etc. may require the use of Densyl Mastic or Denso Profiling Mastic. Refer to the product sheets for these specific products for information on application and selection.
