VFI®-200 50 D Slow Polyurea Coating

Features & Benefits

• Moisture insensitive – low sensitivity when exposed to moisture due to setting speed
• Excellent physical properties – tensile strength and elongation increase durability and longevity
• Slower speed – reduces the chance of unwanted texture on large, flat surfaces
• Withstands thermocycling – will not crack or break due to extreme temperature changes
• Chemical & abrasion resistant – protects against chemical corrosion and resists wearing to maintain original structure
• 100% solids – no VOCs and retains 100% of its thickness after curing

Instructions for Use: 

Surface Preparation  

Ensure surfaces are clean, dry, and free of all contaminants that could affect adhesion. A pressure washer can be used on hard-to-clean surfaces to remove grease and oils. A concentrated chlorine solution works well on mildew, fungus, and algae spots. Sandblasting or grinding the surface will help to remove all loose paint, rust, and scale. For ensured coating longevity and performance, make any needed repairs to the surface before coating. When applying to concrete, it must be aged a minimum of 28 days to prevent blisters from forming under the coating. 

Application 

Before applying VFI-200, premix the Poly (B side) until a uniform mixture is achieved. Bring the material temperature to a minimum of 65°F before spraying. A plural component high-pressure spray rig can be used to apply the material onto the prepared surface. The equipment should be able to spray at 2,500 psi and temperatures between 135°F-150°F. 

The coating should be applied at a minimum of 30 mil passes. If applying several coats, you must stay within the 30-minute open window. The slower speed of VFI-200 allows for easier recoating. If the coated surface will be in direct sunlight, VFI recommends applying a UV-stable topcoat once the coating has cured for complete UV stability. The coated surfaces require a minimum cure of 24 hours before they can be placed into service. 

Cleanup  

To clean application equipment, use xylene or MEK as a cleaning solution. VFI recommends using VFI-8005 Pump Flush when flushing out spray lines to remove all uncured material. 

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 splashproof chemical safety goggles and face protection such as 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-200 contains isocyanate, which causes skin irritation and can be toxic if inhaled as particulate matter. Avoid prolonged breathing of vapors and repeated skin contact. Use only in a well-ventilated area.  

• 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, plus isocyanates for the A side 

Potential Health Hazards  

• May cause stomach distress, nausea, or vomiting if swallowed. B side is toxic and may cause burns. 
• May cause respiratory tract irritation, 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 when in contact with skin and causes severe burns, redness, pain, and blisters. Repeated exposure to this material can result in absorption through the skin, causing a significant health hazard.  
• Causes serious eye irritation or damage: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva. B side may cause burns.  

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