FAA-3 Ionomer Dispersion

Catalog Number	ACMA00063001
Description	This product is an anion exchange ionomer that acts as a binder when using Fumatech anionic membranes, holding the platinum, membrane and gas diffusion layer together. FAA-3 solution is a brown, clear N-methyl-2-pyrrolidone (NMP) solvent solution containing a polyaromatic polymer with quaternary ammonium functionality (counterionic bromide). The solution is ready-to-use and requires no additional additives.
