3 Scotchfil Electrical Insulation Putty Data Sheet 1. Product Description 2. Applications Scotchfil Electrical Insulation Putty is an electrical grade To insulate low voltage (600 volts and less) connections putty in a tape form. Scotchfil putty is UL Recognized as a To build up cable splices and fill out major irregularities splice insulation for electrical conductors at temperatures up and voids in low voltage splices (2300 volts and less) in to 176F (80C) when over-wrapped with either Scotch order to obtain a uniform base for further taping Super 33+ or Super 88 vinyl Electrical Tape. To round out high voltage connections To smooth bus bar irregularities UL Recognized Category OCOT2, File No. E59951 To create a resin dam in resin pressure splices Noncorrosive, synthetic rubber To create a moisture seal at ground wire exit in high Excellent electrical properties voltage splices Excellent aging properties To moisture seal multiconductor cable connections Will not dry out Applies cleanly without waste Typical Properties Physical Properties Color Black Thickness ASTM D-1000 125 mils (3, 17 mm) Elongation ASTM D-1000 1000% Copper Corrosion None Electrical Properties Dielectric Strength ASTM D-1000 575 V/mil (22,6 kV/mm) Insulation Resistance 6 ASTM D-1000 >10 Megohms 3. Specification connectors, shall be first built up with electrical insulating putty to eliminate both sharp corners and voids. Enough The insulating putty must be in tape form, the thickness of insulating putty shall be used until good overall padding is which must be a minimum of 100 mils (2,54 mm). The tape provided. Compress putty to fill all voids and generally must be a rubber based tape capable of being formed and smooth up before applying electrical splice protection. molded with moderate finger tension at temperatures as low All 600 volt or less splices and terminations on wires as 32F (0C). Neither the tape nor any of its components larger than 6 AWG with irregular shaped connectors shall shall cause the corrosion of copper. The tape must be be insulated with a minimum of 1/4 inch (6,3 mm) of compatible with most synthetic cable insulation as well as electrical insulating putty. The entire connection must be other splicing tapes. covered with the insulating putty. The insulating putty must then be over-wrapped with a vinyl tape applied with the 4. Engineering/Architectural Specification same tension as it has when it comes from the roll. This All 2300 volt or less feeder connections, taps and splices, vinyl tape shall provide an uniform covering of at least four on wires larger than 6 AWG with irregular shaped layers, half lapped in two directions.5. Installation Techniques 6. Shelf Life To round out irregular connections, mold and pack Scotchfil Scotchfil Electrical Insulation Putty has a 5 year shelf-life Electrical Insulation Putty with moderate finger pressure, (from date of manufacture) when stored under the following eliminating voids and air spaces. The layers of Scotchfil recommended storage conditions. Store behind present will fuse into a homogeneous mass. Over-wrap with two stock in a clean dry place at a temperature of 70F and half lapped layers of Scotch Super 33+ or Super 88 Vinyl 40-50% relative humidity. Good stock rotation is Electrical Tape. recommended. To create a resin dam in resin pressure splices, wrap a 7. Availability layer of moderately stretched Scotchfil insulation putty around the cleaned cable jacket at a distance of 3.0 inches Scotchfil Electrical Insulation Putty is available in (7,6 cm) from the jacket cutback. Lay the ground wire along 1 1/2 in x 60 in (3,8 cm x 152,4 cm) rolls from your local the cable jacket and through the Scotchfil putty. Wrap 3M authorized electrical distributor. several layers of highly elongated Scotchfil putty around the cable and ground wire. Bind Scotchfil putty tightly with several wraps of Scotch Super 33+ or Super 88 Vinyl Electrical Tape. The putty and vinyl tape will make a seal through which resin cannot flow.
