VFI®-2626 65 D Brushable Hard Coat

VFI®-2626 65 D Brushable Hard Coat

VFI-2626 65 D Brushable Hard Coat is a 1A:3B by volume, two-component polyurethane coating. Since it is applied by brush or trowel, it’s used as a patch repair material with other hard coats or as a hard coating material on small-scale projects. It provides deformable surfaces such as EPS and other foams with structure and high rigidity for protection from impacts. The coating can be textured if desired but can also be sanded, primed, and painted to improve the aesthetics of smaller pieces. VFI-2626 is capable of passing UL-94 V0.

VFI-2626 65 D Brushable Hard Coat from VFI is a brush-applied coating that offers a longer pot life for extended work time on small projects and patch repairs.

Features & Benefits

  • Convenient brush application with no need for large, expensive spray equipment
  • Increases aesthetics of small projects and blends well with existing hard coats
  • High rigidity at 65 D with outstanding resistance to impacts
  • Great for repairs, small sections, and specific curves
  • Pre-measured containers ensure mixing accuracy for quick and easy application
  • Encapsulates surfaces to provide waterproofing and splash protection
  • Capable of passing UL-94 V0

Instructions for Use:

Surface Preparation

Surfaces should be clean and free of oils, dirt, debris, or other contaminants. A primer or additional sanding prep may be required depending on the surface.

  • EPS – The foam must be aged for at least 30 days so any gas can escape. We recommend using 2 PCF foam for an optimal cost-to-quality ratio, but 1-3 PCF is acceptable. Ensure that the surface is clean and dry before you begin applying.
  • Wood – The wood should be dry and contain less than 11% moisture; otherwise, it should be primed or mist-coated (a light dusting followed by the main application of the coating).
  • Metal – The surface must be cleaned by roughly sanding or sandblasting to SP6 to remove rust, mill scale, dirt, and other contaminants.
  • Existing Hard Coat: Surfaces must be sanded and/or primed before application to ensure adequate long-term adhesion.


Thoroughly mix the Poly side (B) before combining. The pot life can be extended by mixing smaller quantities (ex. 200 grams will yield a 15-20-minute pot life while the full mix will yield about an 8-minute pot life). When pouring the material by hand, pour the pre-weighed Iso into the pre-weighed Poly. Mix the two until uniform, then transfer to a new container and mix until uniform again before use. VFI-2626 must be fully mixed and used before the pot life expires. Mix times will vary depending on material volume and mixing method.

For the best results, the temperature must stay between 50°F – 100°F during application. VFI-2626 can be applied to any prepared substrate with a chip paint brush, notched trowel, or squeegee at a minimum rate of 60 mils. The best film properties can be achieved at 100 mils or greater.

Curing will depend on film thickness and substrate temperature. A full cure may take up to 3 days at room temperature. The coated structure can be placed into service after curing at room temperature for a minimum of 24 hours. Higher hardness can be obtained by post-heating between 90°F – 110°F after 6 hours of initial curing. For theming purposes, begin priming or painting the coating at the first sign of cure to maximize adhesion.


Tools and equipment used to apply VFI-2626 can be cleaned with xylene or MEK.


*Always read the safety data sheet before working with chemicals

Use chemicals only as directed and for their intended purpose. Do not dispose of chemicals down the drain. Most chemicals must be disposed of as hazardous waste.

PPE to avoid all unnecessary exposure:

  • Eye protection – wear approved safety glasses and any additional eye protection as necessary
  • Hand protection – wear chemically resistant protective gloves (nitrile, butyl, or neoprene)
  • Skin and body protection – wear suitable protective clothing
  • Respiratory protection – in case of insufficient ventilation, wear suitable respiratory equipment. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product, and the safe working limits of the selected respirator

Product Limitations

VFI-2626 is not UV color-stable and has no long-term UV testing. It must be top-coated if intended for outdoor application. Isocyanate in the A side may be irritating to the skin and toxic if inhaled. Proper protective clothing and a fresh air supply respirator must be used during application. It must be protected from exposure to moisture. Water will cause the A side material to generate carbon dioxide, causing high pressure in sealed containers.

  • Incompatible materials – oxidizers; none known for B side
  • Conditions to avoid – heat and incompatible materials
  • Chemical stability – stable under normal storage conditions
  • Reactivity & hazardous reactions – no dangerous reactions known under normal use
  • Hazardous decomposition products – may include, and are not limited to, oxides of carbon

Potential Health Hazards

  • May cause respiratory tract irritation. A side material may also cause allergy and asthma symptoms or breathing difficulties.
  • May cause skin irritation or sensitization: redness, edema, drying, defatting, & cracking of the skin.
  • May cause serious eye irritation: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva.
  • May cause stomach distress, nausea, or vomiting if swallowed.

*If you are experiencing any of these symptoms, seek medical advice or attention. Call a poison control center or doctor if swallowed.
