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.
