GENERAL DESCRIPTION: EP7120 is a two component, room temperature curing, rigid, filled epoxy system with very thixotropic (no sag) characteristics even on vertical walls. This makes EP7120 particularly attractive in surface coat applications. It can be brushed out very thin or up to ¼" thick. EP7120 is easy to machine and provides good impact and chip resistance.

Recommended mix ratio is 12 parts of A with 1 parts of B, by weight. This provides a 20 minute pot life, and a 24 hour cure time at room temperature. Pot life and cure time will vary depending on temperature, humidity and thickness. The resultant unreinforced epoxy has these properties:

Viscosity: Lite Paste
Specific Gravity: 1.30
Hardness (durometer): 88 D
Shrinkage: 0.2%
Heat Resistance: 180°F
Dielectric Constant: 4.57
Volume Resistivity: 6.1 x 10¹⁵ ohm / cm
Moisture Absorption: 0.6 %
Tensile Strength: 9000 psi
Compressive Strength: 16,000 psi
Flexural Strength: 15,000 psi
Color: ivory (other colors available upon request)
