MTS889

 

Product name: 

 Solderable varnish MARMOT®  MTS889

Description and key properties:

 

  • Electro-isolating solderable varnish
  • For industry and consumer electronics
  • Hardened varnish does not obstruct further soldering
  • When reach temperature of soldering it melts and does not create dross
  • UV fluorescent - can be checked in UV light whether layer is coherent
     

Operating instructions:

Varnish is applied by paintbrush or all other suitable methods.

When necessary to apply more layers than one, next layer is applied after hardening the first layer.

The varnish becomes dry during 30 min.

Full hardening comes in 48 hour / 23°C or 5 min / 80°C. We recommend using warm hardening to reach high electro insulation resistance.

Diluting a washing: OTM 19.

 

Avoid penetration of varnish into connectors and switches!

 

The varnish vas subject of testing of Tesla VUST No.181011514/5, it was compared and tested as electro insulation varnish regardless it is not its nature, it is solderable varnish, but even though passed all tests and examinations.

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.
