Kemklin-109(S)
(Rust Remover By Spray Application)
Product Description
Kemklin-109 is specially formulated to remove mild rust from ferrous
and non-ferrous metals effectively by spray process. Kemklin-109 (S)
is purely based on phosphoric acid enriched with various types of
solvents/surfactants and wetting agents, etc. Kemklin-109(s) attacks
only on rust or scales and it does not attack on the base metal.

Product Operating Procedure
Fill the tank with water and add:
Kemklin-109(s) at the rate of 10% and mixed it thoroughly and raise
the temperature to 35-45°C. prior to dip in Kemklin-109(c) bath,
components should be free from oil, grease, strength and spray time
of Kemklin-109(s) can be increased if the components are heavily
contaminated with heavy rust. After processing in Kemklin-109(s), the
work should be rinsed thoroughly in clean water and subjected to
phosphating bath. Kemklin-109(S) bath can be maintained by simple
titration and does not require any skilled labour or any chemical
knowledge. Bath should always be maintained at operating level with
recommended concentration freshly prepared bath acts rapidly but the
action gradually decreases due to the accumulation of iron
concentration in the bath. Increase the temperature at this stage
accelerates the derusting action, but the temperature should be
controlled and it should not go above 55°C.
Product Application Equipments
Kemklin-109(S) tanks should be lead lined, rubber lined, glass fibre,
rigid polythene, stainless steel tanks made out of 18 gauge sheets
preferred. Steam coil or nozzles should be 316 SS.
Testing and Control Procedure
Pipette out 10 ml. of bath solution and further diluted with 90 ml
of distilled water.
Pipette out 10 ml. Diluted solution into the conical flask and add 2
to 4 drops of indicator methyl orange.
Titrate against N/10 sodium hydroxide solution.
The colour changes from orange red to orange yellow.
If the bath pointage goes down from the recommended level, Add: 8.33
ltrs. Kemklin-109(S) for increasing one pointage in 1000 ltrs. bath.
Iron Concentration
Pipette out 10 ml. of bath solution and add 10 ml. of 50%
concentrated H2SO4. Mix it thoroughly, titrate this against N/10.
Kmno4 solution till the colour changes to light pink stable for 15
seconds. % of iron in the bath is calculated as 0.056 x titrate
reading. Maximum permissible limits of Iron concentration in
Kemklin-103 bath is 7%.
Chemical Replenishment
The bath should be discarded when of concentrated solution and
increase in the temperature does not show faster derusting action and
powder deposits appear on the surface of the metal. Iron
contamination should be more than 7%.
Safety Measures
Kemklin-109 is an acidic liquid material, and while handling proper
care should be taken. Protect eyes and skin by means of goggles, aprons,
gloves, etc. If it comes in contact with skin and eyes, wash thoroughly
with a flush of water and get medical advice.
