CORROSIONPROTECTIONAs a result of extensive field tests the Hoiophane

Companv has devisecl a series of special flnishesdesignecl to provide corrosion protection. T'hese hnishes

are known as PRISMATECT.-pRrsMArECr is applied as a precisely regulated coating

and is baked under controlled conditions.Once cured, pRisMArECr becomes inert and willnot

readily react chemically rvith other materials.pRrsMArECr (P-1) provides protection in conditions where

the equipment is exposed to all grades of chemicalsor fumes-miid to harsh-and for outdoor areas

exposed to extreme salt atmospheres. Order b)'addingthe suffix P-lto the unit catalog number.
