-
works exactly like a contact cement
- start: use like Topfit or Colle de Cologne
- coat both sides, let dry, stick together, done
- dries completely clear
- that’s how you know it’s ready to bond
- on leather, dries within two or three minutes
- on rubber and other compact materials, esp. foams, can take 10-15-20 minutes
- will always turn clear when ready to bond
- foams
- be careful
- absorbent, e.g. PU, take in water
- leather wicks water away
- issue: dried adhesive layer on top, but fed water from the bottom
- use heat
- can bond nearly everything as Topfit
- can press leather together by hand
- wouldn’t use on plastic soling materials
- doesn’t work on vinyl
- will work on synthetic leather
-
more of a building adhesive
- not so much a repairing adhesive
- not for repairing soling because of trouble with shoe plastics
- need to press with fitting last
- does not need to be heat-activated, but can benefit
- orthopedics: need to heat material to make it moldable anyway
- layer thickness
- controls drying speed
- controls success of bond
- too much → won’t work
- high solid content → need to use less
- 1 pint lasts like another quart
- grabs quickly due to high solids
- works on somewhat wet leather
- if wet forming, e.g. cowboy boot soles, making bag gusset, can pre-coat the pieces
- enough to hold together for sewing
- not for shoe soles
- no odor whatsoever
- working at home, small workshops
- not flammable
- easy to shop and haul around
