EP-837 Two-part Epoxy Staking Adhesive

EP-837 Two-part Epoxy Staking Adhesive Description:

Suitable for dot dispense or stencil applications, and exhibits excellent adhesion to most metal and plastic substrates.

EP-837 is designed for component attachment, termination and other applications where low temperature curing conditions are required.

EP-837 has excellent temperature resistance, toughness, and allows for differences in coefficients of thermal expansion between two bonded substrates. Lateral component push-off testing on print treated polyester substrates (PET) show that EP-837 has 30 to 40% greater bond strength than other conductive epoxy adhesives.

Curing Schedule: (Time at Temperature / 90% Cure / Complete Cure):

• 20°C / 48h / 72 hours+
• 140°C / 10-20 minutes / 30-40 minutes

Typical Properties:

Application Guidelines

Dot dispensing can be accomplished utilizing positive displacement or pneumatic actuated equipment. EP-837 exhibits quick breakoff after dispensing in high speed automated production processes. In small volume production environments, EP-837 can be mixed and manually loaded into syringes for dispensing with hand held equipment.

The rheological properties of EP-837 allow for accurate and repeatable dot geometries over a four hour window. While the viscosity of the mixed material will change over four hours, most dot dispense equipment can easily compensate for the rheological changes to accurately maintain dot configuration.

Packaging

EP-837 is available in pre-weighed open containers, or pre-weighed, separated plastic pouches (CC-Paks). There is no minimum purchase quantity with either packaging configuration, and open containers can be ordered with any specified amount of material.
