3M Scotchfil Electrical Insulation Putty 1-1/2 in x 60 in Self-Fusing Mastic Tape

Professional electrical insulation for irregular surfaces and connections

3M Scotchfil Electrical Insulation Putty delivers reliable insulation for irregular surfaces like fittings and valves in electrical applications. This self-fusing, electrical-grade mastic tape stretches and wraps to insulate connections up to 600V, withstanding temperatures from 32 to 176�F (0 to 80�C). The 125-mil thick, non-corrosive mastic adhesive offers optimized adherence in a flexible tape form, making it ideal for sealing multi-conductor cable connections and wire exits at high-voltage joints.

3M SCOTCHFIL – Frequently Asked Questions

1) Can I use Scotchfil putty to insulate a splice without vinyl tape over it?
Scotchfil electrical insulation putty is meant to be the filler layer, not the finished jacket. It builds up an insulating body over irregular shapes, connectors, fittings and wire exits, and it is not self-extinguishing, so common practice is to overwrap it with a vinyl electrical tape or rubber splicing tape for mechanical and flame protection. The putty itself carries a 125 mil thickness and 22,000 V/mil dielectric strength, so it does the insulating work once it is covered.
2) Will Scotchfil hold up in an unheated outdoor enclosure in winter?
Temperature is the limit to watch. Scotchfil putty is rated 32 to 176 degrees F (0 to 80 degrees C), so an enclosure that drops below freezing is outside its rated range. It is sunlight resistant and UV resistant, which covers outdoor exposure, but for below-freezing service look at a splicing product with a lower temperature rating.
3) Will Scotchfil putty conform around an irregular connector or a multi-conductor cable crotch?
That is what it is built for. The putty stretches to 1000 percent elongation before breaking, so it pulls down into the crotch of a multi-conductor cable, around lug bodies, fittings and valve shapes, and fuses to itself with no adhesive residue issue. It is self-sticking and amalgamating, meaning the wraps merge into one mass instead of staying as separate layers.
4) How much Scotchfil putty is on a roll and how far does it go?
Each roll is a strip 1-1/2 inches wide by 60 inches long (38 mm by 1.5 m), 125 mil thick. That is five feet of material per roll, so a roll covers a handful of connector fills rather than a run of splices. Rolls ship 100 to a case for shops standardizing a truck stock.
5) Does Scotchfil putty corrode copper or aluminum conductors?
The mastic is non-corrosive, so it can sit directly against copper or aluminum conductors and connector bodies. That matters on a splice you are burying or sealing up, where a corrosive filler would work on the metal for years out of sight.
6) Does 3M Scotchfil putty carry a UL listing and is it RoHS compliant for a spec job?
Scotchfil electrical insulation putty is UL Recognized, and it is RoHS 2011/65/EU compliant without exemption. Both are the lines a facility or institutional buyer needs on a submittal, and the RoHS status carries no exemption caveat behind it.
7) Does Scotchfil vulcanize or cure once it is wrapped?
No, it does not vulcanize. Scotchfil stays a pliable putty, which is why it can be pulled back off and reworked on a connection that needs to be opened later. A rubber splicing tape that vulcanizes is the choice when you want a cured, permanent jacket instead.
8) How long can Scotchfil putty sit on the shelf before it goes bad?
Five years of shelf life on 3M Scotchfil putty, which is why it works as stocked MRO material rather than something bought per job. Electrical MRO, power distribution and electrical construction are the markets 3M lists it for.
9) What is the correct part number and roll size when ordering 3M Scotchfil?
Order 3M Scotchfil, MPN SCOTCHFIL, black electrical insulation putty in the 1-1/2 in x 60 in roll. There is one size and one color in the line, so there is no width or length to specify beyond the single roll configuration.
