EPOCAP 43645

Main features

  • Two-Component Room-Temperature Epoxy
  • 7,000 psi Tensile Strength
  • 90-Minute Gel Time

Product Description

EPOWELD® 43645/53655 is a two-component, room temperature curing epoxy compound designed for general-purpose adhesive and casting applications. Formerly known as EPOWELD® 3645A/3655B, this versatile system delivers high mechanical strength and is particularly recommended for bonding components in demanding impact environments.

Key features

  • High-strength bonding: Delivers a robust tensile strength of 7,000 psi and a lap shear strength of 4,000 psi on aluminum.
  • Convenient processing: Features a simple 1:1 mix ratio by weight and cures fully at room temperature.
  • Extended working time: Offers a 90-minute gel time for a 100-gram mass, easily accommodating complex assembly or casting processes.

Applications / Suitable for

  • Bonding striking tools such as hammers, axes, and sledge hammers.
  • General-purpose adhesive applications.
  • General-purpose casting applications.

Specific Gravity
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
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
