Lead fluoborate is a nonflammable colorless liquid or crystalline powder. Faint odor.??
Used in tin-lead electroplatingLead(II) tetrafluoroborate is used as a catalyst involved in calixarene formation through hydrogen-bonded dimmers and in the preparation of linear polyesters. It is involved in the development and optimization of a bipolar lead-boron tetrafluoride accumulator. It is an electroplating solution for coating metal objects with lead and curing agent for epoxy resins. Further, it is used in printing lines, tin-lead alloy plating, lead soldering and also as a circuit board tin-lead alloy plating.?? ??
Odorless colorless liquid. An aqueous solution. Sinks and mixes with water.?? ???
Solution is acidic and will corrode most metals [USCG, 1999]. Toxic and irritating hydrogen fluoride gas may form in fire [USCG, 1999].????
Early symptoms of lead intoxication via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis, chiefly of the extensor muscles of the wrists and less often of the ankles, is noticeable in the most serious cases. Ingestion of a large amount causes local irritation of the alimentary tract; pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact with eyes or skin may cause burns and/or irritation.????
Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride gas may form in fire.??? ??
This material is used in material finishing operations.?? ??
