Opti-Check™ Optically Activated Pigments

Source: Sherwin-Williams
Holidays. Pinholes. Imperfections. Whatever you call them the results are always the same—catastrophic.

That's why Sherwin-Williams developed new Opti-Check™ OAP Technology. Opti-Check OAP allows tank lining applicators to instantly identify pinholes, thin spots or any other discontinuities using safe UV light. OAP extends the coatings life by verifying a monolithic application and proper film thickness, eliminating coating application issues. The result: pinholes as small as 0.25 mils can be identified and repaired immediately during initial application before the tank is holiday tested and returned to service. Opti-Check OAP can be used as a one coat or two coat application, and is available with multiple Sherwin-Williams' tank lining materials, including:

  • ExpressCote HCR Novolac Epoxy
  • Fast Clad ER Epoxy
  • Fast Clad Epoxy Primer
  • DuraPlate UHS Epoxy Coating
  • DuraPlate UHS Epoxy Primer
  • NovaPlate UHS Novolac Epoxy Primer
  • Macropoxy 646 PW Epoxy
  • Phenicon HS Phenolic-Novolac Epoxy
