TC Envirotape is a 70 mil wax coating system with an exclusive formulation designed to provide protection against corrosion and electrolysis on wet or dry metal substrates with a maximum operational temperature range of 300°F (149°C)
Using a select blend of petrolatum and microcrystalline waxes provides this wax coating system with its exceptional high temperature capabilities,
TC Envirotape is a highly moldable protective coating that will easily conform to irregular contours and difficult to coat structures.
Environmental friendly and safe to use, TC Envirotape is Ideal for coating fittings, flanges, valves, mechanical couplings, vault piping and other complex configurations.
PRIME - Apply TC ENVIROPRIME by hand (glove) or mechanical means to achieve a 2 to 4 mils thickness.
TAPE - Apply TC ENVIROTAPE using either the spiral or cigarette method. A 50% overlap is preferred, though a minimum overlap 1” or 20 per cent of the tape width, which ever is greater is acceptable when conditions allow. Hand smooth and seal overlaps.
COATING OVERWRAP - TC ENVIRO-STRETCHWRAP– a 1-mil plastic outer wrap to be applied over TC ENVIROTAPE prior to below grade backfill. Other overwrap options are available. (Refer to coating specifications for more detailed application instructions.)
Standards and Practices - ANSI/AWWA C217-09 Petrolatum and Petroleum Wax Tape Coatings for the Exterior of Connections and Fittings for Steel Water Pipelines
Surface should be clean. Remove all loose or non-bonded material, rust scale, dirt, burrs, and sharp edges. Remove excess moisture whenever practical.
