Good Mechanical Properties,

High Reactivity,

Low Viscosity,

Water Resistance

Properties

• Low viscosity and high reactivity
• Compatible with various hardeners, reactive diluents and accelerators
• Low hydrolysable chlorine content and therefore slight tendancy to crystalisation at low temperature.
• Conforms to FDA listing requirements

The resins when formulated yield:

• Superior mechanical and electrical properties
• Execllent chemical and water resistance

Packaging & Availability

Packaging Type

Drums

Package

Razeen® LR 1140 B is supplied in bulk and in 240 kg. steel drums.

Storage & Handling

Shelf life (at storage temperature between 10-50°C)

6 years

Storage

This product has a minimum shelf life of six years when stored in unopened sealed containers in a dry location at room temperature. Like most liquid epoxy resins, Razeen® LR 1140 B may crystallize when stored below room temperature. Heating the resin to 60-70°C (140- 160°F), for several hours will re-liquefy it and restore its original properties.
