Cleaners based on NaTG

Sodium Thioglycolate (NaTG) is used in cleaners for:

– Rims

– Flash rust

– Concrete and marble

– Derouging

The big advantages of these kind of cleaners are:

• they are acid free. Thats why they are non corrosive for coatings, aluminia,

steel, concrete and marble.

• this cleaners are very powerful against the dust from the brakes and

against iron.

Step 1: Spray the rim cleaner on the dirty rim.

Step 2: If necessary take a brush. After a few minutes wash the rim with a water

jet.

The rim is free of dirt also at places which can´t be reached by the brush (inner

side of the rim).

Rim cleaners- Raw Materials -


6

Bruno Bock produces 3 different aqueous solutions of

NaTG:

NaTG 23: Not of interest for cleaners.

NaTG 46: Typical for rim cleaners.

NaTG 46 l.o.: Also typicall for rim cleaners. NaTG l.o.

contains an additive which gives the product a better smell.

NaTG l.o. should be preferred for this application.

Part II: Basic formulas

Typical properties of NaTG-based Rim Cleaners:

• pH-range 6,5-8

• NaTG-content 7-16 %w/w calculated as pure NaTG

• Higher NaTG-concentrations of above 15 %w/w are

beneficial if flush rust in on the metallic surface
