VFI®-2519 75 D Brushable Hard Coat

Features & Benefits

• Convenient brush application with no need for large, expensive spray equipment
• High rigidity with outstanding resistance to impacts
• Increases aesthetics of small projects and blends well with existing hard coats
• Great for repairs, small sections, and specific curves
• Pre-measured containers ensure mixing accuracy for quick and easy application
• Extended pot life allows for vertical application without sagging
• Room temperature cure without the need for post curing

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.

Application

Premix the Poly side (B) until uniform before combining it with the Iso side (A). 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). If pouring the material by hand, the pre-weighed Iso must be poured into the pre-weighed Poly. Mix the two until uniform, then transfer them to a new container and mix until uniform again before using. VFI-2519 75 D Brushable Hard Coat must be fully mixed and used before the pot life expires. Mix times will vary depending on material volume and mixing method.

For proper adhesion, the temperature must stay between 50°F – 100°F during application. VFI-2519 can be applied to any prepped substrate with a brush or trowel at a minimum rate of 60 mils. The best film properties can be achieved at 100 mils or greater. After the material cures, it can be sanded and painted to improve the aesthetics of the piece for material theming.

Cleanup

Tools and equipment used to apply VFI-2519 can be cleaned with xylene or MEK.

Safety

*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-2519 is not a UV color-stable product and has no long-term UV testing. If it’s applied to a project meant for exterior applications, it must be top coated. Isocyanate in the A side may be irritating to the skin and toxic if inhaled.

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

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