• Usable on wood, metal, concrete, and platinum-cured silicone surfaces
• Ultra clear, bubble-free resin with the ability to be pigmented

Instructions for Use:  

Surface Preparation 

Ensure the surface is clean, dry, and free of contaminants that may affect the material. If you are casting the material, you must apply a release agent to prevent it from adhering to the molding surface. If you are pouring it onto a porous surface, it must be sealed to prevent off-gassing or foaming from moisture. You can apply a thin layer of the epoxy as a seal coat using a brush. Then, pour a thicker layer if necessary.

Application  

The material must be thoroughly mixed, and measurements must be exact for the material to cure properly with full physical properties. This material is a 2A:1B by volume or 100A:44B by weight. Bring both components to at least 65°F before use and premix the B side material. Pour the measured B side into the A side. Mix the material with a paddle mixer by occasionally scraping the sides and bottom of the mixing container. Transfer to a new, clean container and mix again to achieve a thorough, uniform mix.

Mixing times may vary depending on volume and mixing method. CAUTION: Depending on the overall volume being poured, the pour depth, and the ambient temperature, excessive heat may build up. Due to the exothermic reaction generated, only mix what you are ready to pour. The more you mix, the hotter the material will be, and it may cause fumes and smoke.

Epoxy is temperature-sensitive. Work in a room-temperature environment between 60-80°F with low humidity and good ventilation. Cooler conditions are recommended for deep and high-volume pours to achieve the best clarity and finish. Working above 80°F can cause the material to become too hot, causing yellowing, cracking, and shrinking. Using a fan in your work environment can help with airflow.

Make sure the surface is level, and pour the material into the mold or form until the desired thickness is met. It can be poured in layers up to 4 inches thick. If you are pouring less than 1 inch thick, use a material with a faster pot life and cure time. If you pour above the maximum thickness, the epoxy may create excessive heat, causing the material to yellow, shrink, or crack. Pour in layers if your project must go above 4 inches.

Cure time can vary depending on working temperature, material temperature, volume, mold material, and thickness. At 1 inch thick, VFI-4723 will be cured to the touch and can be removed from a mold after 3 days at room temperature. Full properties will develop after 7 days at room temperature.

Once cured, it is easy to work with for sanding, buffing, or completing any other post-work. If applying more layers, stay within the 24-hour repour window to ensure the layers adhere together. If the surface fully hardens, it must be sanded between pours. It can be scuffed with 80-grit sandpaper after 36 hours.

Most epoxies are not UV-resistant and will discolor, become brittle, and degrade from prolonged exposure. VFI recommends using a UV-stable top coat if the epoxy is in direct sunlight.

Cleanup  

VFI recommends cleaning resin or mixed epoxy residue with lacquer thinner, acetone, or denatured alcohol.

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 with side shields that are resistant to chemicals or tightly sealed/fitted splashproof chemical safety goggles and a face shield 
• Hand protection – wear chemically resistant protective gloves (nitrile, butyl, or neoprene) 
• Skin and body protection – wear suitable protective clothing to protect from skin contact 
• Respiratory protection – in case of insufficient ventilation or when risk assessment shows air purifying respirators are appropriate, wear suitable full-face 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-4723 is not intended for outdoor use and has no long-term UV testing. The material may be toxic if inhaled, swallowed, or in contact with skin. Wear all necessary PPE to avoid prolonged exposure, including an approved respirator. Avoid breathing in vapors or repeated skin contact. Use only outdoors or in a well-ventilated area.

• Incompatible materials – A side: strong oxidizers, acids, amines, and bases. B side: strong oxidizers and acids 
• Conditions to avoid – N/A
• Chemical stability – stable under normal storage conditions 
• Reactivity & hazardous reactions – no dangerous reactions known under normal use 
• Hazardous decomposition products – may include and are not limited to oxides of carbon, as well as oxides of nitrogen for the B side 

Potential Health Hazards  

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

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