VFI®-7203 Ablative High-Build Silicone

VFI-7203 Ablative High-Build Silicone is a single-component silicone that is applied using a brush or trowel and does not require mixing. It has low adhesion for easy removal from most metal surfaces for faster repairs without the need of scraping or abrasive blasting. This product has excellent hang on vertical surfaces while still maintaining its flexibility and ablative properties.

  • Single component for easy application without mixing
  • Holds on vertical and horizontal surfaces at 250 mils

Instructions for Use: 

Surface Preparation 

VFI-7203 Ablative High-Build Silicone is used in conjunction with the VFI-7200 Ablative Silicone Series. It should be applied to the substrate after thorough surface preparation is achieved and primers or coatings are applied. Make necessary repairs and ensure the surface is clean, dry, and free of contaminants. A power washer may be needed for hard-to-clean areas.  

Application  

VFI-7203 is a moisture-cure silicone that can only be applied by trowel or brush for optimal coverage. While there is no limit to how thick it can be applied to a surface, it will start to sag at greater than 500 mils as it fully cures. Ambient and surface temperatures must be greater than 40°F during application. The speed at which the coating cures will increase at higher temperatures. Before application, the material temperature should be at least 60°F. Do not apply VFI-7203 if rain and other moisture contaminants are present.  

Cleanup  

When cleaning application equipment, VFI recommends using chemically dry mineral spirits.  

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  

  • Incompatible materials – 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 – may include, but are not limited to, oxides of carbon  

Potential Health Hazards   

  • May cause respiratory tract irritation. 
  • May cause stomach distress, nausea, or vomiting if swallowed.  
  • May cause skin irritation and sensitization: redness, drying, defatting, and cracking of the skin. 
  • May cause eye irritation: discomfort, pain, excess blinking and tear production, possible redness, and swelling.  

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