Technical Data Sheet

MTL401

 

Product name: 

 MARMOT® Flux MTL401

Description and key properties:

  • Upgraded version of commercially successful flux 
  • Non aggressive Electro-insulation Organic flux based on refined
    natural resin with high reduction effect
  • Activated without content of halides
  • For hand and automated soft soldering in electronics with solder Sn60-63%Pb
  • For aviation, military devices and for soldering color metals
  • Application, where is the need of higher content of less activated flux 2 – 3% such as soldering automates, where higher content of flux compensates inaccuracy of solder tip
  • 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 standard Tin Lead  multicored 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.
