VFI®-3131 65 A Polyurea Hybrid Spray Coating

Features & Benefits

• A 65 A hardness gives the coated layer impact resistance and good rebound
• Can be used to create an aesthetic for small and large interior and exterior projects
• Easy spraying and a slower gel time allow it to spray smoothly in a single pass
• Formulated with fire retardant to meet fire safety requirements

Instructions for Use:  

Surface Preparation

When the surface is not properly prepared, coating failure will occur. Clean all surfaces of contaminants such as oils, dirt, or debris for ensured adhesion. Some surfaces may require a primer, so an adhesion test should be performed before coating.

When applying over foam, it should be aged for at least 30 days to allow any gas to escape. We recommend non-recycled EPS bead 2 PCF foam for an optimal cost-to-quality ratio. Foam between 1-3 PCF is also acceptable. Once clean and dry, VFI-3131 can be applied directly to the foam.

Application

Bring VFI-3131 to a minimum temperature of 70°F before use. Premix the Poly (B side) until uniform before spraying. The time it takes to mix the product will depend on volume and mixing method. All powder should be mixed in from the bottom of the drum. The A side does not need to be premixed.

VFI’s recommended specifications for a high-pressure, plural component spray rig is to run it at 150-155°F and 2,500 psi constant pressure with high-pressure heated hoses and 10 ft whip hoses. Gun tips will vary by project and will need to be adjusted on site.

For light-duty applications, 40-80 mils must be sprayed to develop a uniform film that protects the piece. 80-120 mils of coverage should be sprayed for heavy-duty applications when more physical abuse is expected. Subsequent coats can be applied as necessary within the 20-minute recoat window. Coating outside of the recoat window could result in intercoat adhesion problems.

Once cured, VFI-3131 must be top coated with paint or an equivalent coating for protection from UV rays. While the finished project can be placed into service in as little as 6 hours with light application, complete curing will take up to 3 days.

Cleanup

VFI recommends cleaning tools and spray equipment with xylene or MEK. Immediately after spraying, flush spray lines with VFI-8005 Pump Flush to prevent damage from product buildup.

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 eye protection (properly fitted dust or splash-proof chemical safety goggles) and face protection (face shield)
• Hand protection – wear chemically resistant protective gloves (nitrile, butyl, 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

This product contains isocyanate, which may irritate the skin and is toxic if inhaled as particulate matter. Avoid prolonged breathing of vapors and repeated skin contact. Protect from exposure to moisture.

• Incompatible materials – A side: strong bases, acids, alcohols, amines, and water. B side: strong oxidizers and acids
• 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 – may include, and are not limited to, oxides of carbon and oxides of nitrogen as well as isocyanates for the A side

Potential Health Hazards

• A side material may cause allergy and asthma symptoms or breathing difficulties if inhaled. May also cause respiratory tract irritation. B side material may be fatal if swallowed and enters airways. It may also cause burns.
• A side material causes skin irritation and sensitization, including redness, edema, drying, defatting, and cracking of the skin. B side material causes severe skin burns, including redness, pain, and blisters. Repeated exposure to this material can result in absorption through skin, causing a significant health hazard.
• A side material causes serious eye irritation, including discomfort or pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva. B side material causes serious eye damage and may cause burns with similar symptoms as the A side material.
• Both materials 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.
