VFI®-270 70 A Polyurea Spray Coating

Features & Benefits

• Excellent abrasion, chemical, and scratch resistance
• Extremely fast setting for a quick turnaround on projects
• Creates a flexible, smooth surface that is durable against impact
• Effective bonding to properly prepared surfaces
• Great resistance to thermocycling for outdoor use
• Low viscosity makes for easy mixing and spraying

Instructions for Use:

Surface Preparation

Coating failures often occur when the surface is not properly prepared. Clean all surfaces of contaminants such as oils, dirt, or debris for ensured adhesion. The surface must be sealed with a release agent, especially if it is porous and you plan on demolding. Some surfaces may require a primer, so an adhesion test should be performed before coating. VFI’s recommended primers include VFI-#11 and VFI-1007. When applying over foam, allow the foam to age for at least 30 days so any gas can escape.

Application

Before spraying, the B side (Poly) material must be mixed until uniform. Mixing time will vary based on the volume of material used and the mixing method. Bring the material to a minimum temperature of 65°F. The surface temperature should be between 40°F – 100°F during application.

VFI-270 should be sprayed using a high-pressure, high-temperature two-component spray rig. The spray equipment should be capable of heating the product and providing at least 2,300-2,500 psi of constant pressure. We typically recommend spraying between 40 and 80 mils for the best coverage. More coats can be applied for improved impact resistance. Projects can be put into service in as little as 4 hours, depending on application thickness, but full cure occurs in 3 days.

Cleanup

VFI recommends using xylene or MEK as a cleanup solvent. When flushing through spray lines, VFI-8005 Pump Flush can be used to remove the material from the hoses.

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, fitted dust or splash-proof safety glasses and a face shield
• 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-270 contains isocyanate, which may irritate the skin and is toxic if inhaled. Avoid prolonged breathing of vapors and repeated skin contact. This product is not UV color stable and has no long-term UV testing.

• 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

• May cause stomach distress, nausea, or vomiting if swallowed. The B side is toxic and may cause burns.
• May cause respiratory tract irritation. A side may cause allergy and asthma symptoms or breathing difficulties. B side may cause burns.
• Causes skin irritation and sensitization: redness, edema, drying, defatting, and cracking of the skin. B side is toxic upon contact with the skin and causes severe skin burns, redness, pain, and blisters. Repeated exposure to the 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. B side may cause eye damage and burns.

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