VFI-2075 75 A Flexible Polyurethane

Thickness Requirements

To develop a uniform film over the surface, apply the coating at a minimum rate of 60 mils or 1/16th of an inch. If subsequent coats are needed, apply them within the 30-minute recoat window for ensured adhesion.

Surface Preparation

Surfaces should be clean, dry, and free of oils, dirt, debris, or other contaminants. A primer and additional sanding prep may be required depending on the surface. Use sandpaper between 40-120 grit. Ensure the environment and surface temperatures are between 60-90°F during use. As temperatures increase, working time decreases. If it is too cold, your material might not cure properly.

Equipment

VFI-2075 can be applied to any prepped surface with a chip paint brush.

Mixing

Premix the POLY “B” component until uniform before combining it with the ISO “A” component. If you are adding pigments to your mix, you can add them to the “B” component during this step. The material should be at least 65°F before use; otherwise, at lower temperatures, it will become thicker and harder to use.

VFI recommends using a working gram scale to measure the “A” and “B” materials by weight, which is 10A:1B. Pour your measured “A” component into your measured “B” component and mix with a paint or wooden stick until the color is consistent all the way through. Using power or meter mixing equipment may introduce too much air into the mix.

If you are pigmenting the material, pouring the “A” side into the pigmented “B” side will make it easier to tell if you’ve mixed the material thoroughly. VFI-2075 must be fully mixed and used before the 4-minute pot life expires. Mix only what you believe you can apply to the surface within the pot life. Mix times will vary depending on material volume and mixing method.

Post-Cure

The material will cure after 16 hours at room temperature. If you would like to speed up the curing process, it can also be heated in an oven at 150°F for 4 hours. If the coated project will sit outside for extended periods of time, you may want to apply a compatible UV-stable top coat. The top coat would have to be applied within the 30-minute recoat window.

Storage/Shelf Life

The shelf life of unopened containers is 6 months after the date of manufacture. Store the product between 60-90°F in a clean, dry building. Once open, use it immediately. After opening, it is possible to store unused material by nitrogen purging both sides immediately after use.

Precautions

VFI-2075 is not a UV color-stable product and has no long-term UV testing. If it’s applied to a project meant for the outdoors, it must be top-coated. It is moisture-sensitive and may bubble if exposed to too much moisture. Isocyanate in the A side may be irritating to the skin and toxic if inhaled. Avoid prolonged breathing of vapors or repeated skin contact. Use only with adequate ventilation. Do not thin or add foreign material to this product.
