Packaging & Storage

VpCI® 384 is available in 4-gallon (15.1 liters) kits, 3 gallons Part A, 1 gallon Part B. Product shelf life is 1 year.

Application

Surface preparation is crucial for ensuring proper adhesion of the coating to the substrate. Before application, the substrate must be thoroughly cleaned to remove any contaminants or rust inhibitors. The surface should be free of dirt, grease, oil, fingerprints, and drawing compounds. Use a pre-treatment component such as 440 on production lines.

In the case of structural steel, use NACE No.3/ SSPC - SP 6. However, before proceeding with the full-scale application, it is essential to ask Cortec® and/or perform adhesion tests on the system.

When dealing with aluminium, galvanised or plated surfaces, apply first a wash primer using VpCI 373 before coating with topcoat VpCI® 384. Depending on the specific coating requirements, you can also use other recommended primers such as 395 & 396.

To ensure the application process goes smoothly, the dew point should be at least 2°C, which is lower than the room air temperature.

Regarding the mix ratio, prepare the coating as follows: 3 parts Part A (3 gal/11.3 l) and 1 part Part B (1 gal/3.8 l). Achieve an even viscosity through agitating. You can use a cylindrical or hand-held mixer. The VpCI® 384 can be applied using various methods such as spraying, rolling, brushing, or dipping.

For those using a pressure pot setup during mixing, allow 15-30 minutes of sweat-in time before application. The pot life of the mixture is 2-3 hours. Optionally, Super Accelerator S can be added to accelerate the cure time, with a maximum of 6 oz. per gallon.

By following these guidelines and ensuring proper surface preparation and mixing, the application of VpCI® 384 will yield the best results for your project.

Clean Up

When the paint is still wet, wash the equipment and tools with butyl acetate immediately. Use Butyl Cellusolve or MEK when it's dry. When using any solvent, follow the manufacturer's precautionary recommendations.
