Technical Data Sheet

MTR961

 

Product name: 

 MARMOT® Flux MTR961

Description and key properties:

 

  • Non aggressive Electro-insulation Organic flux
  • Highly activated without halides
  • For hand and automated wetting soldering in electronics solder Sn60-63%Pb
  • For wave soldering after diluting
  • For soldering high-end, military electronics and avionics even
    mildly oxidized color metals
  • Flux concentrate – dilute according to used process of soldering
    and solderability of soldered parts 
  • Flux neutralize itself after soldering depending on process of production
  • The flux is not suitable for soldering by naked flame – it is highly flammable
     

Operating manual:

Flux is applied by foam, spray or wetting.

Flux can be accordingly diluted to minimize residues after soldering

Other proprieties: Solid substance read safety data sheet if released

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.
