By Denso
Moisture Tolerant Pipeline
Liquid Coating
|
Description |
Denso
Protal 7300 is a VOC-free, 100% solids, epoxy coating specially
formulated to coat dry, damp or wet surfaces for galvanic protection and
corrosion control. It is a high-build liquid
coating that is Denso Protal Applicator Pad, Denso Protal 9" Roller, or
brush applied in one coat in the field or shop. |
|
Uses |
For the exterior coating of pipelines, structures or other steel surfaces
that may be wet or damp due to the environment or as a result of atmospheric
condensation. |
|
Features |
•
Can be applied to wet or damp surfaces.
• High build (up to 50 mils in one coat).
• Excellent adhesion to wet and damp surfaces.
• Safe and environmentally friendly.
• Excellent gouge, abrasion and impact resistance. |
|
Surface
Prep |
Prepare surfaces by grit blasting to a clean near white finish, SSPC SP-10/
NACE No. 2. Material for abrasive cleaning shall be the appropriate blend of
grit to produce an angular surface profile of 2.5 - 4 mils (0.063 - 0.10
mm). |
|
Application |
•
Initially stir the base and hardener.
• Add the hardener to base and mix until a constant color is achieved.
(Make sure all sides of container are scraped).
• Pour mixed material onto surface.
• Apply with Denso Protal Applicator Pad, Denso Protal 9" Roller, or brush
(If applying to wet surface, displace water as the coating is applied).
• A wet film thickness gauge shall be used periodically to measure mil
thickness throughout the application process. |
