3M Scotchcast 470W Resin – 2 Part Polyurethane Cable Jointing Resin (Standard)

Scotchcast 470W Resin

3M Scotchcast Resin 470W is a non-filled, 2 part polyurethane cable jointing resin for temperature curing – the Scotchcast Resin has been specifically designed for electrical insulation and mechanical protection of resin cable joints.

3M Scotchcast Resin 470W once hardened provides impact resistance and durability against moisture and atmospheric corrosion and has an operating temperature of installed product -40°C to + 110°C.

470W resin is used to encapsulate 3M LVI-1 armoured power cable joints.

Scotchcast 470W  mechanical protection and electrical insulation of low voltage electrical joints installed for indoor and outdoor, underground and submerged applications.

3M Scotchcast 470W Resin

2 Part Polyurethane Cable Jointing Resin (Standard) Features

  • Resin has excellent hydrolytic stability
  • Available with closed mix and pour delivery system
  • Low exothermic reaction temperature
  • Mechanical protection and electrical insulation of low voltage electrical joints installed for indoor and outdoor, underground and submerged applications

Scotchcast 470W Resin is contained in two chamber bags for quick mixing – the cable jointer must ensure careful mixing of the resin/hardener prior to pouring into the 3M Scotchcast cable joint. No gloves are required, 470W utilises 3M Closed Mix & Pour resin delivery system.

3M Scotchcast 470W resin DESCRIPTION

3M Scotchcast Resin 470W will be supplied, in two-chamber plastic pouches with peelable barrier in the correct stoichiometric proportion. This type of packaging will assure the correct mixing ratio for applying the resin – a Closed Mix and Pour Delivery System.

The integrated pouring spout is opened while attaching the mixed resin bag to the housing of the cable joint shell, or by using the supplied opener. Scotchcast resin 470W has a shelf life of 36 months when stored between 10°C and 40°C with a humidity level < 75 % in the originally sealed bag.
