SR-600

Stainless Steel Scale Remover

You can apply NABAKEM SR-600 by using a soft brush or spray machine to the various structures, equipment,
pipes, chemical reaction containers, boilers, and tank lorries, all of which are made of austenitic stainless steel, to remove multiple scales, thermal oxides, and rusts on them. NABAKEM SR-600 is featured by
simultaneous pickling and passivation. This product is essential for pickling and passivation of the various plants
of nuclear power stations, special chemical vessels, reaction containers of food, medicines, and cosmetics,
various stainless steels, industrial equipment, and structures.

Features:

Simultaneous pickling and passivation
High adhesiveness ensuring prevention of stream down after reaction. No gas.
Long-time (24 hours) leaving after application does not cause over- picklingorgas cavities.
Chromic acid or aqua regia not contained.
Physical properties not changed by long-term storage.
Easy removal by rinsing.

How to use:

More effective after removing oil contents, slag, spotter, wax, tar, scales and rusts before use.
※ Use it in itself or to adjust its dilution ratio (from 1 time to 20 times) with water according to the degree of
contamination.
Apply the product evenly by using soft brush or spray machine (Apply it in the same direction when using brush.
This does not cause stains.)
Adequate application thickness is 1mm and adequate applied surface temperature is 15~25℃.
Avoid direct sunlight when acidizing in summer seasons. It is more effective to use it in the mornings and
evenings. Application in the evenings and rinsing next mornings is generally used.
Acidizing in winter season indoors is more effective.

Acidizing time should be minimum 30 minutes (at 25℃). When temperature is low, it is better to lengthen
acidizing time.
Do not keep the SR-600 applied surface dried by direct sunlight in summer season. After reaction is finished, the
color of applied surface becomes light blue.
Flush the applied surface with copious quantities of water after application.
Neutralize and rinse the applied surface (High-pressure rinsing is more effective).
You must wear protective equipment like rubber gloves, boots, protective clothing and safety goggles.
