PROTAL
7000
By Denso
High
Build Pipeline Coating - Brush Grade
| Description |
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. |
| Uses |
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. |
| Features |
• 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. |
| Application |
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. |
| Packaging |
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. |
| Storage |
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. |
| Cleaning |
Clean equipment
with solvent cleaner (xylene 95%, butanol 5%). |
| Health & Safety |
Wear protective
clothing and ensure adequate ventilation. Avoid contact with skin and eyes. See
