Technical Data Sheet

MTL561

 

Product name: 

 MARMOT® Flux MTL561

Description and key properties:

 

  • Non aggressive Electro-insulation Organic flux
  • Highly activated without halides
  • For hand and automated soft soldering in electronics with lead-fee (RoHS) solders MARMOT®
  • For soldering high-end, military electronics and avionics even mildly
    oxidized color metals
  • High performance of this flux allows using minimal content of the flux
  • For soldering components with the high rating of solderability, it is possible
    to supply solder (cored wire) with lower content of the flux
  • It is mainly appointed as a filling of the cored wire solder
  • The flux is not suitable for soldering by naked flame – it is flammable

Operating manual:

It is exclusively filled into the patented lead-free cored wire solders MARMOT®

For aviation and military devices is recommend cleaning, for other usage we recommend to test the influence of flux residues on the device, according to the aspect of device and process of production.
In all other application where the small residuum of the flux after soldering does not affect the product
is not necessary to apply cleaning.

Safety and health protection

 

 

11.1.

Long lasting and repeated contact with skin can cause irritation and sensibility, therefore is necessary to avoid direct contact.  In case when it is not possible exclude possibility of direct skin contact, the workers must wear suitable personal protective equipment. Work area must be ventilated. Do not drink or eat during work. Do not use naked flame. After work, hands should be washed with soap and warm water and cared with protective cream.

 

 

11.2.

First Aid

 

Inhalation – in case of excessive inhalation of flux fumes emitted during soldering, remove affected person to fresh air.

Ingestion – in case of accidental Ingestion, wash out mouth with water and give enough pure water to drink.

Skin contact – in case of skin contact, wash the place with soap and warm water.

Eye contact – in case of eye contact, flush the eyes immediately with plenty of water.

In case of large health damage or eyes contact, seek medical attention. 

 

11.3.

Above mentioned precautions are recommended for health protection of the workers, obligatory measures are described in Safety Data Sheet (SDS) - if released, and do not substitute internal safety regulations of final customer.
