VFI-8403 Dryer

VFI-8403 Dryer is an accessory product to help with moisture contamination and issues for polyurethane and polyurea hybrid products. It is mixed into the polyol side (B) to eliminate existing moisture before combining with the isocyanate side (A) and helps to reduce foaming.

Application

This product was only designed to be added to the Polyol side (B) and should NOT be added to the Isocyanate side (A). VFI recommends adding half a percent or less of VFI-8403 to the total volume of the Polyol container. Do not exceed more than 1% because it will cause the final product properties to change. Mix for 15 minutes so the dryer has enough time to react with the existing moisture in the system.

Cleanup

The preferred cleanup solvent is xylene or MEK. Do NOT use water as a cleanup solvent for this material.

Storage/Shelf Life

The shelf life of unopened containers is 6 months from the date of manufacture. Store the product between 60°F – 90°F in a clean, dry building. Once open, use immediately.

Precautions

Keep out of contact with water, as this may cause a severe chemical reaction. Avoid prolonged breathing of vapors and repeated skin contact. Do not add foreign material to the product. Use only with adequate ventilation. See Safety Data Sheet for complete safety information.
