KPNOX 27 GEL is a ready-to-use citric acid passivation gel designed to deeply remove rust, corrosion, free iron contamination, heat tint, lime scale, discoloration, and microbiological deposits from stainless steel surfaces. Compatible with ASTM A967 passivation practices, this fast and efficient stainless steel treatment helps restore corrosion resistance without altering the original surface finish.
Its convenient gel formulation allows easy application on stainless steel equipment, welds, piping, tanks, and industrial process surfaces. KPNOX 27 GEL is applied directly to the surface for 5–10 minutes and rinsed off with water only — no additional neutralization required.
Ideal for pharmaceutical, food-grade, sanitary, marine, and industrial stainless steel maintenance applications.
