Effective Cleaning for Isocyanate Residue
GSP NZD ISO Flush – 5 Gallon (Part A – ISO Only), part number 02-W359585-5, is a chemical cleaning solution designed specifically for removing Part A (ISO) residues from spray foam system components. Built for high-performance applications, it dissolves both hardened and liquid ISO without introducing moisture into the system. This is critical for preventing rust and corrosion in proportioners, hoses, pumps, and fittings.
