Abstract
Method of currentless deposition of tin on a catalytic surface by means of a highly alkaline solution which contains stannous ions in a quantity of at least 0.20 mole/l and is used at temperatures of 60.degree. to 90.degree. C. The solution operates on the basis of the mechanism of disproportioning of stannous ions. The tin deposition is, however, accelerated by means of a strong reducing agent such as a hypophosphite.
