Liquid Epoxy Resin

Description
ESRES EA-417300 is the standard, undiluted, general purpose, diglycidyl ether of Bisphenol-A epoxy resin.

Applications
• High-solids and solvent-free high-build coatings
• High-pressure laminating
• Castings
• Adhesives
• Electrical potting and encapsulating
• Functional and decorative flooring
• Filament winding

Features
• High heat distortion temperature
• Medium high viscosity
• Good reactivity
• Good resistance properties

Properties 

Viscosity, at 25°C, cps 12,500
Color, Gardner 1 max
Pounds per Gallon 9.65
Epoxide Equivalent Weight 185

Storage
ESRES EA-417300 may crystallize during extended storage or when stored at low temperatures. Resin that has crystallized can be remelted by holding at 130°F to 150°F until all crystals have melted. Warm storage (130°F to 150°F) is recommended. Remelting of crystallized resin has no negative effects on performance.

Small differences in any of these factors will make a difference in the gel time of the resin/hardener mix. It is advisable, therefore, to determine gel time of the mix under actual working conditions.
