Protal 7000 High Build Pipeline Coating, Brush Grade, by Denso

High Build Pipeline Coating - Brush Grade




Denso Protal 7000 is a VOC free, 100% solids epoxy coating specially formulated to complement FBE coated pipelines. It is a high build liquid that is hand applied in one coat to many areas during pipeline construction in the filed or shop. It cures fast to allow quick backfill when necessary.


On-site liquid coating of girth welds, tie-ins, welds for boring applications, repairs to FBE, fittings and fabrication. It may also be used for rehabilitation of existing pipelines.


• Fast cure.
• High build (in one coat).
• Can be applied with brush or roller.
• Excellent adhesion (complements FBE coated pipe).
• High abrasion resistance for drilling applications.
• Safe and environmentally responsible.
• Does not shield cathodic protection.


Prepare surfaces by grit blasting to a clean near white finish, SSPC-SP 10/ NACE No. 2. Mix each of the base and hardener to an even consistency. Add the hardener to base and mix until an even color is achieved making sure all sides of container are scraped. Immediately pour mixed material onto surface and brush, trowel or roll to required mil thickness. A wet film thickness gauge shall be used to measure mil thickness. If surface temperature falls below 50°F (10°C), surface must be preheated to maintain good application properties. Preheat may be achieved with a propane torch or induction coil. Base component shall be kept warm, at a minimum of 68°F (20°C), to achieve easy mixing properties.


1.0, 1.25, 1.5, 1.75 and 2.0 liter kits (packaged separately: 8 base per case and 16 hardeners per case). Special kit sizes available.


Minimum of 24 months when stored in original containers above 40°F
(4°C). On job site where temperatures are below 68°F (20°C), product must be kept warm to mix properly.


Clean equipment with solvent cleaner (xylene 95%, butanol 5%).
