Additin® RC 5250

Type

neutralizable EP-additive for water miscible metal working fluids

Application

– water miscible metal working fluids (synthetic and emulsifiable MWF)

Additin RC 5250 in water-based systems displays multifunctional properties:
EP-performance, lubricity, corrosion inhibition and co-emulsification. Typical treatment levels in MWF
concentrates are 2 to 10 %.

Additin RC 5250 is emulsifiable in water by neutralization with inorganic alkalizing agents or alkanolamines. Using
tap water with high hardness, a well-balanced combination with Calcium dispersants is necessary.

Additin RC 5250 increases the EP-performance and lubricity during the machining of steel and light metals. A
synergistic EP-performance can be achieved in emulsifiable or semi synthetic MWF in combination with Additin
RC 2526 or Additin RC 2540.

Furthermore Additin RC 5250 is an alternative to tall oil fatty acids.

Solubility

After neutralization Additin RC 5250 is generally well soluble in water miscible concentrates. However, it is
necessary to verify the solubility in the base fluids used and the compatibility with other additives.

Additin RC 5250 is not soluble in mineral oils.

Packing Unit

200 kg bunghole drums

Storage Conditions

In a dry place at room temperature approx. 24 months. Storage conditions at low temperatures can cause partially
cristallisation, which is reversible by stirring and heating up to 50°C. For warming only indirect heating devices are
allowed and the temperature of the heat source must not exceed the flash point. Direct contact of product or
packaging with heating devices and local overheating over 60°C – even for short time – must be avoided.

Handling

Consult material safety data sheet (MSDS) for additional handling information on Additin RC 5250.
