Fracture Repair & Containment Coating

The repair of random cracks and application of a coating in a secondary containment area was a major concern at this airplane manufacturing plant. Due to the limited shutdown time and low October temperatures most conventional coating systems were ruled out.

VersaFlex rapid curing polyurea sealants and coatings were specified and successfully installed. The random cracks were ground out and filled with VersaFlex SLl 75, which took less than I hour to cure.

Aqualok concrete sealer and primer was then installed to inssure proper bonding.

versa micro VersaFlex FSS 45 DC-F polyurea spray, with a 5 second gel time, was applied at a film thickness of 65mils.

The entire project was completed from start to finish in just 4 days, which was half the time it would have taken using a conventional coating system.

Corrosion and severe abrasion were two serious problems at this industrial phosphate facility. Maintenance engineers had tried several coating systems over the preceding years in an effort to protect both steel and concrete surfaces.

While various epoxy systems offered some protection they were short lived and took far too long to cure at time of installation.

After in depth research, it was determined that a rapid cure polyurea system might be the solution.

VersaFlex was consulted and a polyurea metal coating system was specified for all surfaces. The approved VersaFlex contractor installed versa micro VersaFlex FSS 50DM spray coating to the top of the clarifier tanks to protect steel from dripping 28% phosphoric acid.

In addition, numerous steel support beams were coated for protection against 5% fluosilic acid vapor, which is highly corrosive.

Both shaft and flights on the gypsum filter table needed protection from 10% phosphoric acid as well as the abrasive gypsum in order to extend the auger life from 1 to 3 years.
