Description |
Denso Protal 7125 is specifically formulated to be applied to colder substrates at colder ambient temperatures. It is a high build liquid coating that is hand applied in one coat to many areas of in-service pipelines or during pipeline construction in the field or shop. It cures fast to allow quick handling and backfilling, even down to -4°F (-20°C). Protal 7125 is intended for use where a quick cure is required at lower substrate and/or ambient conditions such as during winter applications or on colder operating temperature pipelines. It will also cure after being submersed in water. |
|
Uses |
Used as a rehabilitation coating for existing low temperature in-service operating pipelines, station piping, girth welds, tie-ins, push rack (laybarge applications), abrasion resistant coating for boring applications, repairs to FBE, fittings and fabrication. It may also be used for new construction where colder temperatures exist and preheating or post heating is not practical or feasible. |

Features |
• Cold temperature application down to -4°F (-20°C) |
|
Application |
Prepare surfaces by grit blasting to a clean near white finish, SSC-SP 10/ NACE No. 2. (Repair areas shall be roughened using Carborundum cloth or 80 grit sandpaper and wiped clean with an isopropyl alcohol soaked cloth prior to patching.) Open container to prepare for mixing and remove both foil pouches. Cut open larger foil pouch, Part “A” and empty the white contents into mixing container, then cut open and add the smaller foil pouch, Part “B”. Thoroughly mix both components to a consistent gray color using a wooden stick or power mixer. During the mixing process, the inside surface of the container should be scraped to obtain a complete mixture. Pour mixed material onto surface and brush, trowel or roll to required thickness. A wet film thickness gauge shall be used to measure mil thickness (min. 20 mils). Backfilling times are dependent on temperature and will be extended at cooler temperatures. Note: Denso recommends surface temperature during application to be a maximum of 68°F (20°C) for optimum performance characteristics. |
