72050005 - Antox 90E Stainless Steel Passivating Paste 5kg

Finish Your Stainless Welds with Confidence

Every professional welder knows that a stainless steel weld isn't truly finished until it's cleaned and protected. After you've pickled your weld to remove the heat tint and slag, the metal is left raw and vulnerable. The Antox 90E Passivating Solution Paste is your insurance policy against rust coming back. This 5 kg jar provides a powerful passivating agent that instantly restores the protective oxide layer on the steel's surface, locking in the clean finish and blocking out corrosion.

Designed for the real-world shop environment, this paste is easy to use. Simply mix it 1:1 with water and brush or spray it onto the treated area. It works quickly—within 20 to 30 minutes—so you aren't holding up the production line. Unlike liquid solutions that might drip off vertical welds, the paste consistency helps it stay where you put it, ensuring the chemical does its job exactly where needed. It's the perfect final step after using a strong pickling paste, neutralizing any leftover acid and leaving the metal bright and passive.

Why Passivation Matters

Mechanical grinding or heavy pickling strips away the natural protection of stainless steel. Without a helper like Antox 90E, that protection takes a long time to grow back naturally, leaving your hard work open to pitting and rust in humid environments. By using this passivating solution, you guarantee that the customer receives a product that looks great and lasts. It is an essential consumable for any shop working with food-grade equipment, tanks, or architectural stainless steel where appearance and longevity are critical.
