VFI®-3001 70 A Polyurethane Casting Rubber

Features & Benefits

• Easy processing for use in an injection molding system
• Easily pigmented for adjustment and addition of available colors
• Chemical, stain, and antimicrobial-resistant urethane rubber
• Fast-setting for quick demolding and improved part production
• Low viscosity for varying part sizes that maintain final properties

Instructions for Use:

Mold Preparation

Ensure all surfaces are clean and free of oils, dirt, debris, and other contaminants. The molding surface must be sealed and covered with a release agent for ease of demolding. Release agents are required to help prevent unwanted adhesion and prolong the life of the mold. Compatible molds for injecting include urethane, metal, and platinum silicone when prepared properly. Heating the mold between 70°F-150°F can accelerate the curing process, allowing for faster demolding. However, increasing the surface temperature beyond 72°F will shorten the pot life.

Molding Process

The B side (Poly) material must be premixed before using VFI-3001. The material’s short working time only allows for injection molding applications. A proportioner is required to inject the material. VFI recommends using a different material with a longer working time for parts requiring more than 3 minutes of gel. The casting can be demolded after curing for at least 8 minutes at room temperature. The part does not have to be post-cured to achieve full properties and will obtain these properties after 5 days. You can achieve full physical properties faster if you post-cure the material in an oven at 150°F for 16 hours.

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

VFI-3001 contains isocyanate in the A side material and may irritate the skin. It is also toxic if inhaled as particulate matter. Avoid prolonged breathing of vapors and repeated skin contact.

• Incompatible materials – A side: water, alcohols, amines, bases, and acids. B side: 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 – A side: carbon monoxide, carbon dioxide, nitrogen oxides, hydrocarbons, and HCN. B side: may include, and are not limited to, oxides of carbon

Potential Health Hazards

• May cause respiratory tract irritation if inhaled. The A side material may also cause allergy and asthma symptoms or breathing difficulties.
• Causes skin irritation or sensitization: redness, edema, drying, defatting, and cracking of the skin.
• Causes serious eye irritation: discomfort, pain, excess blinking and tear production, marked redness, and swelling of the conjunctiva.
• 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.
