Liquid Electrical Tape is an air-dried, synthetic rubber coating that can be brushed on and exhibits excellent moisture, acid, alkaline, abrasion, and dielectric resistance. Offers far more efficient sealing than sticky cable seals and tape. Perfect for quick access and portability! Great for sealing all antenna connections. The coating is flexible making it ideal for use on portable antenna connections. Tests we have done show that the product, unlike many other sealants, does not affect the Q of toroids used at HF - it has good dielectric properties and low losses. Liquid Electrical Tape remains flexible even under extreme conditions and won\'t crack, harden, or peel. Electrically insulates to over 1380volts/ml. Liquid Electrical Tape is excellent for use in a variety of applications including electrical connections and components for boats, trailers, cars and lorries, timers, outdoor wiring, instruments, computers, circuit boards, switches, radio antennas, and many more. Easily removed from non-porous surfaces. Supplied in a 4 fl.oz (118ml) container, with applicator brush mounted in the lid. Colour - Black. One can contains enough Liquid Tape for dozens of connections.
