Tape:  Glass Cloth  (High temperature electrical wiring tape)

 

Tape: Glass Cloth

  • Glass Cloth Tape No.27 is a high heat splicing tape composed of a glass cloth locking and an adhesive that thermosets in high heat application environments. 
    It is a Class B 266F (130C) electrical insulation.

  • Catalog No.27 - 1/2" wide x 66' long

Cement:  High Temperature

    Cement:  High Temperature
  • This cement insulates electricity but radiates heat.  It also resists acids, oils, and temperatures up to 3000F.  This is the same cement Hotwatt uses in electric heating elements and can be used for electric kilns, furnaces, and resistors.  The cement hardens into a porcelain-like body by air drying without the use of kilns or injury to the finest resistant wire.

  • Catalog No. C-78, 1 Quart Container.


Wire: 
High Temperature Hook-up



Features

  • The high temperature insulated wires are for use in internal wiring of domestic, commercial,
    and industrial heating, cooking, and process equipment.

  • Wires are suitable for service up to the rated voltage in damp and dry applications with wire
    temperatures up to 250C (482F); with intermittent use in ambients as high as 650F.

  • Wires are identical to that used on our own heating elements.

  • Available in 100 foot and 250 foot spools.

Resistance Wire:  Nickel Chromium

Features

  • Hotwatt's nickel-chromium wire (80ni-20cr) is proven to deliver outstanding performance over
    extended periods of time and is the same wire we use in our own electrical heating elements.

  • Uniformity of resistance

  • Mechanical stability

  • Fine surface finish

  • Consult factory for specifications on other sizes and different alloys which are available.
    Typically Iron-Chromium-Aluminum alloy, Nickel-Iron Alloy, and Thermocouple Alloys.

Heater Release and Transfer Agent

   Hot Lube

Hot Lube

 

  • Hot Lube can greatly reduce heater-to-bore seizure when properly applied.

  • Improves Thermal Conductivity.  Heat transfers more quickly from heater to part
    being heated when Hot Lube is used.

  • Increased Heater Life.  Tighter fit made practical with use of Hot Lube.

  • Not electrically conductive.

  • Hot Lube solution is not considered hazardous.

  • Easy to use.

  • Withstands Temperatures to 1600F (875C).

  • 4 oz. covers approximately 1500 square inches.

Directions

  • Heater surface should be clean and dry.

  • Shake Hot Lube well before use.

  • Brush on a light uniform coat of Hot Lube.

  • Allow to air dry for 20 minutes or oven dry at low temperature (140F maximum).
