VFI®-2075 75 A Flexible Polyurethane

Features & Benefits

• Cure can be sped up with a 4-hour oven bake at 150°F to obtain properties faster
• 75 A flexible coating that handles extreme conditions without tearing
• Tintable formula for coating surfaces that require a desired aesthetic
• Good adhesion to EPS foam, fabrics, wood, and braided cable

Instructions for Use:

Surface Preparation

Surfaces should be clean, dry, and free of oils, dirt, debris, or other contaminants. A primer and additional sanding prep may be required depending on the surface. Use sandpaper between 40-120 grit. Ensure the environment and surface temperatures are between 60-90°F during use. As temperatures increase, working time decreases. If it is too cold, your material might not cure properly.

Mixing

Premix the POLY “B” component until uniform before combining it with the ISO “A” component. If you are adding pigments to your mix, you can add them to the “B” component during this step. The material should be at least 65°F before use; otherwise, at lower temperatures, it will become thicker and harder to use.

VFI recommends using a working gram scale to measure the “A” and “B” materials by weight, which is 10A:1B. Pour your measured “A” component into your measured “B” component and mix with a paint or wooden stick until the color is consistent all the way through. Using power or meter mixing equipment may introduce too much air into the mix.

If you are pigmenting the material, pouring the “A” side into the pigmented “B” side will make it easier to tell if you’ve mixed the material thoroughly. VFI-2075 must be fully mixed and used before the 4-minute pot life expires. Mix only what you believe you can apply to the surface within the pot life. Mix times will vary depending on material volume and mixing method.

Application Process

VFI-2075 can be applied to any prepped surface with a chip paint brush. To develop a uniform film over the surface, apply the coating at a minimum rate of 60 mils or 1/16th of an inch. If subsequent coats are needed, apply them within the 30-minute recoat window for ensured adhesion.

The material will cure after 16 hours at room temperature. If you would like to speed up the curing process, it can also be heated in an oven at 150°F for 4 hours. If the coated project will sit outside for extended periods of time, you may want to apply a compatible UV-stable top coat. The top coat would have to be applied within the 30-minute recoat window.

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 fitted, chemically resistant safety glasses and a face shield if a splash hazard exists
• Hand protection – wear chemically resistant protective gloves (nitrile, butyl, neoprene)
• Body protection – wear suitable protective clothing that covers all exposed skin
• 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-2075 is not a UV color-stable product and has no long-term UV testing. If it’s applied to a project meant for the outdoors, it must be top-coated. It is moisture-sensitive and may bubble if exposed to too much moisture. Isocyanate in the A side may be irritating to the skin and toxic if inhaled. Avoid prolonged breathing of vapors or repeated skin contact.

• Incompatible materials – A side: water, alcohols, amines, bases, and acids. B side: oxidizers
• Conditions to avoid – heat and incompatible materials
• Chemical stability – stable under normal storage conditions
• Reactivity & hazardous reactions – no dangerous reaction known under normal use
• Hazardous decomposition products – A side: carbon monoxide, carbon dioxide, nitrogen oxides, hydrocarbons, and HCN. B side: 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 if inhaled.
• Causes skin irritation or sensitization: redness, edema, drying, defatting, and cracking of the skin. Repeated exposure to the B side material can result in absorption through the skin, causing a significant health hazard.
• Causes 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.
