Capable of making tin cans? (7)

I believe the answer is:

stannic

I'm a little stuck... Click here to teach me more about this clue!

'capable' is the definition.
Both the answer and definition are adjectives.
Perhaps they are linked in a way I don't understand?

'making tin cans?' is the wordplay.
'making' is an anagram indicator.
'tin'+'cans'='tincans'
'tincans' is an anagram of 'STANNIC'.

'of' is the link.

Can you help me to learn more?

(Other definitions for stannic that I've seen before include "Relating to one type of tin" , "Of tetravalent tin" , "Of one form of tin" , "Relating to a form of tin" , "containing tin" .)

I've seen this clue in The Times.
