75% Potassium Isooctanoate & 25% Diethylene Glycol (K-15)

Overview

K-15 is a solution of about 75% potassium isooctanoate (potassium 2-ethylhexanoate) in diethylene glycol, supplied as a light yellow liquid. It is a trimerization catalyst that promotes isocyanurate formation in rigid foams.

Also known as

K-15; Potassium 2-ethylhexanoate solution; Potassium octoate in DEG
