Product Description
EPOCAP® 47577/57577 (formerly EPOCAP® 17577) is a two-component, room temperature curing epoxy encapsulation system specifically designed for protecting submersible pump equipment. It features excellent cured properties and is formulated with non-abrasive inert fillers, making it well-suited for processing through automated dispensing equipment.
Key features
- Flame retardant: Recognized to meet UL 94 V-0 flame retardancy standards at a thickness of 0.250".
- Machine-friendly formulation: Contains non-abrasive inert fillers that minimize wear and facilitate ease of use in automated dispensing equipment.
- Extended working time: Provides a long pot life with a gel time of 206 minutes for a 100-gram mass at 25°C, accommodating large or complex potting applications.
Applications / Suitable for
- Encapsulation of submersible pump equipment.
- General potting applications requiring UL 94 V-0 flame retardancy.
- High-volume automated dispensing processes.

Specific Gravity
1.52 g/cm³
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
Physical Properties
Viscosity
3,500 (Mixed) mPa.s
Viscosity is a measurement of a fluid’s resistance to flow.
Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.
A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.
The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application
