I re-tubed a lot of Ribs, my opinion is : unacceptable work if it were done like explained by the customer.
- glue-to-fabric compatibility : it is a must, hypalon glue cannot fit pvc or PU, was it the right glue ?
- glue age : most glues last ONE YEAR from manufacturing date, when not opened and correctly stored. Check for the date, it must be printed on the can.
Shops do not hesitate to sell 3 years old glue ...
- glue quality : I know several very good "2 components glue for hypalon", but I know ONE for pvc.
There are others for sure, but I don't know them ...
The one I know comes from South Africa, it works perfectly on pvc and Hypalon. maybe PU.
When used as recommended, it is stronger than the fabric itself !
Directions for use :
- clean locally the pvc fabric with acetone or MEK, dry with air gun
- apply the glue (pre-mixed with 5% of hardener), one layer on each fabric stripe (2 for hypalon)
- heat slightly to remove possible condensation
- let return to ambient, then connect both sides - no adhesion occurs unless heating starts, with a heat gun (Leister).
- adhesion starts around 30/35°, this is very helpful to place the parts in the perfect position
- but full strength is obtained when 60/65° is reached
- ambient working conditions : clean surfaces, dry air, fresh glue with the right % of fresh hardener, clean hands, gloves ...
When one has to glue in an opened garage, with rainy weather outside, great care must be taken to avoid condensation occuring just after the glue is applied, and into the glue bowl itself ... so small quantities at a time !
The same when one wants to glue hypalon.
For a good job, a closed garage is a must, with air conditionning system to keep the air dry and around 18/20°C.
