Coal Diversion Gate Repair
Flexane® 80 Putty

Problem:
These metal gates used to divert minerals for classification would receive extreme abrasive wear. The
previous method of repair was to attached hardened plate or ceramic tiles to the gates. Attaching
hardened plate added significant weight and the ceramic tiles would often break due to impact abrasion.
Solution:
The complete surface area of the metal gate was sandblasted to a SSPC-SP5 white metal finish. Surface
area was then chemically cleaned using Cleaner Blend 300. Both FL10 and FL20 Primer were applied to
the metal gate surface area and each allowed to cure or dry for 15 minutes. Applying both primers will
improve adhesion of Flexane from 25 pli to 50 pli. Flexane 80 Putty was applied on the metal gate to a
thickness of 1/8”. Urethane sheets, (.750” thick), were fabricated to cover the metal gates. Urethane sheet
contact surfaces were roughened and chemically cleaned using Cleaner Blend 300. RU80 Urethane
Primer was applied to the urethane covers and allowed to cure or dry for 15 minutes. A thin coat of
Flexane Brushable was applied to the urethane covers to completely wet out the surface. The urethane
sheets were positioned and compressed into place. Flexane 80 Putty provided a long lasting, flexible
bond of the urethane sheets to the metal gates.
