Properties

• Medium viscosity and high reactivity.
• Compatible with various hardeners, reactive diluents and accelerators.
• Low hydrolysable chlorine content and therefore slight tendancy to crystalise at low temperature.

The resins formulated yield:

• Superior mechanical and electrical properties.
• Excellent chemical and water resistance.
• Excellent flow.

Packaging & Availability

Packaging Type

Drums

Package

Razeen® LR 2282 is supplied in bulk and in 220 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 6 years when stored in unopened sealed containers in a dry location at room temperature. Like most liquid epoxy resins, Razeen® LR 2282 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.
