A flow agent/ surfacing agent/ wetting agent unique to the epoxy industry.In laminating, it helps wet the fiberglass, reduces the amount of resin needed, and most of all eliminates blush. Blush is what causes the banana peel effect. In hot coats it eliminates blush, fish eyes, other surface blemishes, and increases Barcol hardness. This increase in Barcol makes the board sand easy and improves the bond and strength between layers. It also doesn't interfere with recoating as wax solution in polyester does. That means no sanding between layers. How to use Additive F: 1cc per ounce Hardener for Laminating 2cc per ounce Hardener for Hotcoating
