Technical Data Sheet

MTR302

 

Product name: 

 MARMOT® Flux MTR302

Description and key properties:

  • Liquid low residue flux for other application
  • For hand soldering, wetting and high frequency heating in electronics with lead-fee (RoHS) solders MARMOT®
  • Activated by unique MARMOT® patented combination of hydro-halide and inhibitor of corrosion
  • For soldering high-end electronics even highly 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:

Applicable by suitable tool or dip soldered part in the flux

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.
