Koch Chemie AF Active Foam | pH 9.5 Mild Alkaline Snow Foam | Phosphate & NTA-Free
Koch Chemie AF Active Foam — Alkaline Cleaning, Certified Paint-Safe
Active Foam is a highly concentrated, mildly alkaline pre-wash foam for when a neutral foam isn't quite enough. At pH 9.5 it pulls off more traffic film and grime, yet it's certified VDA Class A paint-safe — approved for a dwell of up to five minutes at the correct dilution.
Cleaner chemistry, high foam
It's phosphate- and NTA-free, built on a high ratio of anionic surfactants for genuine cleaning power and a thick, clinging foam — with a sandalwood scent. It suits gantry, self-service and hand-wash use.
How to use it
Through a dosing pump it runs anywhere from undiluted to 1:10; as a hand wash, around 1:300. Keep the reaction time within five minutes and never let it dry on the surface, then rinse thoroughly.
What you're buying
A concentrate, not a ready-to-use foam — it is diluted before it goes in the cannon. We stock it in 1 L and 10 L. At 1:300 for hand washing, a litre goes a very long way.

Complete the 3-pH wash — mix any brand
Alkaline lifts organic grime, acid dissolves minerals, neutral foams and washes without stripping your protection. Pick a product for each step from whichever brand you like — the neutral foam is optional.
