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. Sold as a concentrate by weight (5 kg / 21 kg).
