Benjamin Moore HP4000 Polyamide Epoxy – Formerly Corotech V400 | Industrial-Grade Epoxy Coating

*****FREE SHIPPING*****

2 GALLON KIT OPTION Includes A and B

Benjamin Moore HP4000 Polyamide Epoxy (formerly Corotech V400) is a professional-grade, two-component epoxy designed for demanding industrial and commercial environments. Engineered for use on machinery, structural steel, tanks, concrete floors, walls, and more, HP4000 forms a highly durable, chemical-resistant cross-linked film that stands up to solvents, abrasion, and even immersion.

This epoxy coating bonds exceptionally well to ferrous and non-ferrous metals, galvanized surfaces, masonry, and concrete, making it a versatile solution for a wide variety of substrates. The polyamide formulation delivers excellent durability and performance in severe service conditions, while the two-component system ensures a reliable, consistent mix with no measuring required—just combine the pre-measured “A” and “B” components.

KEY FEATURES:

• Formerly Corotech V400
• Durable, cross-linked epoxy film for long-term performance
• High resistance to chemicals, solvents, and abrasion
• Suitable for immersion service
• Excellent for industrial floors, tanks, machinery, steel, and walls
• Adheres to concrete, masonry, ferrous, non-ferrous, and galvanized metals
• Two-component, pre-measured mix – no guesswork

Whether you're protecting industrial equipment, flooring, or structural steel, HP4000 delivers long-lasting durability and resistance where it counts.

USAGE: Designed for coating items including tanks, machinery, floors, structural members, walls and other industrial and commercial substrates requiring a durable and resistant finish. The base component dictates the color of the mixed kit, while the catalyst determines the gloss and film build level.

SURFACE PREPARATION: Surfaces must be clean, dry and free of all grease, dirt, dust, oil and wax. Clean all surfaces using HP6000 Oil & Grease Emulsifier. Remove all remaining loose paint, rust and mill scale via Hand Tool Cleaning (SSPC-SP 2) or Power Tool cleaning (SSPC-SP 3). Fill holes and cracks and sand smooth. Glossy surfaces must be fully deglossed. Moderate to heavily rusted areas must be thoroughly prepared and active rust should be properly removed. All masonry surfaces must be allowed to cure a minimum of 30 days before painting. Acid etch or abrasive blast all slick, glazed concrete or concrete with laitance. For acid etching, follow all manufacturer’s directions and safety instructions. Rinse thoroughly and allow to dry.

PRIMER SYSTEMS: 

• Ferrous Metal: HP1550 Concrete and Metal Epoxy Primer is recommended in areas where adequate surface preparation is not possible. In highly corrosive areas where additional rust inhibitive qualities are required, prime with one coat of HP4600 Epoxy Mastic. 
• Galvanized, Aluminum and Non-Ferrous Metals: Prime new or un-rusted metal with HP1100 Acrylic Metal Primer or HP1750 Waterborne Bonding Primer. Weathered galvanized should be primed with HP1550 Concrete and Metal Epoxy Primer.
• Concrete and Masonry: Prime concrete with one coat of HP1550 Concrete and Metal Epoxy Primer, HP1560 Quick Set Epoxy Floor Sealer or HP4000 can also be used.
• Previously Painted Surfaces: HP4000 can be applied over most old industrial finishes in good condition.Test patches are recommended to check for wrinkling or lifting of existing coatings. HP1550 Concrete and Metal Epoxy Primer may be used as a barrier coat over all existing coatings.

MIXING INSTRUCTIONS: This is a two-component product and is preproportioned for error free mixing. Mix “A” & “B” separately.

1. Carefully empty the entire contents of HP4000 Part B and the contents of HP4000 Part A component resin into a separate metal pail, large enough to hold both Part A and Part B, scraping the sides of both parts to ensure all liquid has been added.
2. Using a drill mixer at low speed, blend this mixture for three to five minutes until completely blended. Keep the mixing blade turning at a slow speed to minimize whipping air into material. Scrape sides of pail during the mixing process.
3. Allow to induct for 30 minutes at 77 °F (25 °C) prior to application.

APPLICATION: 

• Airless Spray (Preferred Method): Tip range between .015 and .019. Total fluid output pressure at tip should not be less than 2000 psi.
• Air Spray (Pressure Pot): 704 or 765 air cap and Fluid Tip E.
• Brush: Natural Bristle only
• Roller: Industrial Cover with Phenolic core. ¼” –½” nap.

NOTE: Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with HP7040. Do not thin. Special Note: To ensure complete clarity of HP4000.00 Clear, this item should only be catalyzed with HP4000.90 Gloss Catalyst. The use of the Semi-Gloss Catalyst (HP4000.91) will give the clear a hazy look. Where non-skid characteristics are desired, hand broadcast an appropriate anti-slip aggregate into the wet film then back-roll to encapsulate. HP6300 works well for opaque finishes although will be noticeable in clear finishes. All epoxy coatings will chalk and fade if applied on exterior surfaces subjected to direct sunlight. All epoxies tend to yellow. Where color and gloss retention is important, top-coating will be necessary. HP4000 will stain with prolonged exposure to some solvents and chemicals or in kennels if exposed to animal waste. This staining will not affect the durability or protective qualities of the coating. Do not apply if material, substrate or ambient temperature is below 45 °F (7.2 °C). Relative humidity should be below 90%. Do not apply if within 5 degrees of dew point or if rain is expected within 12 hours of application.

LIMITATIONS:

• This product will not cure at surface temperatures below 45 °F (7.2 °C).
• This product will amber and chalk if exposed to sunlight. Where color and gloss retention is important, top-coating will be necessary.
