TROUBLESHOOTING CURING
PROBLEM
PROBABLE CAUSE
SOLUTION
Slow Curing
(More than 24 hours)
a) Processing temperature is too cold
b) Improper material ratio
a) Warm the room. A minimum of 24
hours is needed at 72˚ F (22˚ C). If
correct temperature conditions cannot
be maintained, a longer time will be
needed for full cure.
b) Verify the pump has the correct ratio.
REFER TO SERVICE SECTION on
lower cylinders.
Soft Spots
(Tire does not fully cure and low
temperature is not suspected)
a) Contamination in the tire carcass.
Contamination sources: water,
calcium chloride, sealants and bead
lubricants
b) Improper mixing of product
a) Small areas can be re-pressurized
using a Carlisle TyrFil approved
sidewall injector. Larger areas
where the whole tire is affected, will
require dismounting, removal and
reprocessing.
b) Check mixer. Replace missing, dirty
or broken elements. Always use the
correct number of mixing elements.
