Product Description
3Mâ„¢ Scotchcastâ„¢ Resin 40G is a non-filled, two component polyurethane resin for room temperature curing. The resin has been designed for electrical insulation and mechanical protection of electrical cable joints.
The 40G resin is classified as LIW (low voltage insulation water curable) according
Cenelec HD 631.1 S2 Standard.
Once cured, the resin provides impact resistance and durability against moisture and atmospheric corrosion.
Continuous operating temperature of installed product; -40°C to + 110°C
Application
Mechanical protection and electrical insulation of low voltage electrical joints installed for indoor and outdoor, underground and submerged applications.
Features
Good adhesion to metals and different plastics.
Hydrophobic behaviour during the curing stage.
Excellent hydrolytic stability
Available with Closed Mix and Pour Delivery System
Low exothermic reaction temperature.

Usage Information
The resin 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.
The expiration date of each product appears on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, it is the responsibility of the user to determine applicability of the resin.
