DESCRIPTION Viking Microfast° and MicrofastHP® Quick Response Pendent Sprinklers are small, thermosensitive, glass-bulb spray sprinklers available in several different finishes and temperature ratings and K-Factors to meet design requirements. The special Polyester,Polytetrafluoroethylene (PTFE), and Electroless Nickel PTFE (ENT) coatings can be used in decorative applications where colors are desired. In ad- -- - dition, these coatings have been investigated for installation in corrosive atmos- pheres and are listed/approved as corrosion resistant as indicated in the Approval t Charts. (Note: FM Global approves ENT finish as corrosion resistant. FM Global has no approval classification for PTFE and Polyester coatings as corrosion resist- ant.) 2.
