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.
