Product Description

 

3M™ Scotchcast™ Resin 1402FR is a halogen free, flame retardant, two component polyurethane resin for room temperature curing. The resin has been designed for flame retardant and chemical resistant properties as well as electrical insulation and mechanical protection of electrical cable joints.

The 1402FR resin is classified as MIW (medium voltage insulation water curable) according Cenelec HD 631.1 S2 Standard.

Once cured, the resin provides impact resistance and durability against moisture, hydro carbons and atmospheric corrosion.

Continuous operating temperature of installed product; -40°C to + 110°C

 

Application

 

Electrical insulation and mechanical protection of low and medium voltage electrical joints installed for indoor and outdoor, underground and submerged applications in conditions where flame retardancy and/or resistance to chemicals such as hydro carbons is required.

Usage Information

 

The resin will be supplied in two-chamber plastic pouches with peelable barrier in the correct stoichiometric proportion, ensuring the correct mixing ratio for applying the resin. This packaging includes a Closed Mix and Pour Delivery System. The integrated pouring spout is opened while attaching the mixed resin bag to the housing of the joint, or by using the supplied opener.

For the 7.18 Litre Mix-pack version of this product, the resin will be supplied in separate cans for component parts A & B in the correct stoichiometric proportion, ensuring the correct mixing ratio when the cans are mixed together. The Mix-pack also includes protective gloves, and a mixing spatula, along with instructions.

 

For other information, relevant for the usage of the resin, like Gel-Time, Pot-Life, viscosity, density etc. please see above the typical properties.

 

Storage

 

3M™Scotchcast™ Resin 1402FR has a shelf life of at least 36 months when storedbetween 10°C and 40°C with a humidity level <75% in the originally sealed bag. The shelf life of the 7.18 Litre Mix-pack version is 12 months, due to the alternative packaging and larger volume. 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.

Safety and Handling

 

3M provides its customers with a product specific Material Safety Data Sheet

(MSDS) to cover potential health effects, safe handling, storage, use and disposal information. 3M strongly encourages its customers to review the MSDS on its products prior to their use.

 

Product Stewardship

 

3M has a fundamental concern for all who make, distribute and use its products, and for the environment in which we live. This concern is the basis of our philosophy and policies by which we assess the health and environmental information on our products and then take the appropriate steps to protect employee, the public health and the environment.
