Pre-weigh the A (Iso) and B side (Poly) material by weight or volume according to the technical data sheet. Pour the Iso into the Poly and mix until uniform. Scrape the bottom and sides of the mixing container to ensure a thorough mix.

Brushable hard coats must be mixed precisely to allow the proper chemical reaction to occur so the coating cures. The trick to using these hard coats is to mix up smaller quantities to extend the pot life. A full mix of VFI-2519 75 D Brushable Hard Coat or VFI-2626 65 D Brushable Hard Coat will yield an 8-minute pot life. If you mix a smaller amount, like 200 grams, it will yield a 15-20-minute pot life.
