DESCRIPTION <br /> Viking Microfast�"and MicrofastHP�Quick Response Pendent Sprinklers are small, <br /> thermosensitive, glass-bulb spray sprinklers available in several different finishes �-,.�«. <br /> and temperature ratings and K-Factors to meet design requirements. The special <br /> Polyester,Polytetrafluoroethylene (PTFE), and Electroless Nickel PTFE (ENT) py <br /> coatings can be used in decorative applications where colors are desired. In ad- <br /> dition, these coatings have been investigated for instalfation in corrosive atmos- <br /> pheres and are cULus listed as corrosion resistant as indicated in the Approval <br /> Chart. (Note FM Global has no approval classification for PTFE and Polyester <br /> coatings as corrosion resistant.) <br /> 2.
