      A tin opener is something for opening tins
      That's for peeling potatoes    

(remember that after prepositions and conjunctions we use -ing)
but if we are talking of a particular use of something we can't use "for"

      I need a tin-opener to open this tin


You can never say FOR TO !

She went home to have dinner  (not: She went home for to have dinner)
