VFI-110 75 D Injectable Plastic

VFI-110 75 D Injectable Plastic is a fast-setting, rigid urethane plastic with high strength and a quick demold time for increased part production. Its low viscosity allows it to be used in a reaction injection molding system with reduced air bubbles and waste. Depending on application needs, the plastic can produce a smooth glossy or matte finish. When primed, it is fully paintable, and it cures tough to be machined or sanded. VFI-110’s high amine content provides good temperature stability and chemical resistance to make repeatable castings for a variety of applications, including industrial part-making and prototyping.

Superior physical properties for industrial part-making and prototyping
High amine content offers good temperature stability and chemical resistance
Ultra-easy 1A:1B formulation helps to eliminate costly off-ratio mixes
Room temperature cure without need for post curing
Fast setting for quicker demold times to increase part production rates
Matching A and B viscosities allow for easy and consistent injection
Fully cured castings are tough, durable, and easily paintable

Thickness Requirements

VFI-110 does not have a thickness limit, but if the part you are injecting exceeds 5 pounds, a different material that has a longer working time should be used.

Storage/Shelf Life

Store between 60°F – 90°F in a clean, dry building. The shelf life of unopened containers is 12 months after the date of manufacture. Once open, use immediately, but if storing after opening, both sides must be nitrogen purged.

Mold Preparation

The mold must be clean and free of oils, dirt, or debris. All surfaces in contact with VFI-110 must be properly sealed and coated with a release agent to prevent unwanted adhesion. Applying a release agent will also help prolong the life of the mold. Heating the mold between 70°F-150°F before injecting can accelerate the curing process. Compatible molds include urethane, metal, and platinum silicone when properly prepared.

Mixing

Before combining the A side (ISO) and B side (Poly) material, premix the B side material. A proportioner is required to inject the material into a mold. As a fast-setting material, VFI-110 does not need to be vacuum degassed. The primary application method is to inject the material.

Post-cure

The casting can be demolded after 5 minutes if greater than 125 mils thick or 10 minutes if less than 125 mils. The material should be allowed to cure at room temperature for 16 hours. It does not require post-curing to achieve full properties. Full physical properties can be achieved in 7 days.

Precautions

This product contains isocyanate, which may irritate the skin and is toxic if inhaled as particulate matter. Avoid prolonged breathing of vapors or repeated skin contact. Use only with adequate ventilation. Do not thin or add foreign material to the product. See Safety Data Sheet for complete safety instructions.
