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.
