Epoxy Adhesive
Description
Hysol 9436 is an unfilled two part room temperature curing epoxy adhesive with excellent strength retention at elevated temperatures. It consists of a liquid resin and curing agent. Hysol 9436 yields rigid bonds that are resistant to salt spray and humidity exposure. This adhesive can also be used for laminating and for potting small assemblies.

Handling
Mixing: This product requires mixing two components together just prior to the application. Complete mixing is necessary. The temperature of the separate components prior to mixing is not critical, but they should be at room temperature.

Application
Mixing – Bulk: Combine Part A (resin) and Part B (hardener) in the correct ratio and mix thoroughly. This is important! Heat build-up during or after mixing is normal. Do not mix quantities greater than two pounds as dangerous heat build-up can occur. Mixing smaller quantities will minimize the heat build-up.
Application: Bonding surfaces should be clean and dry. For optimum surface preparation, consult Dexter's bulletin "Preparing the Surface for Adhesive Bonding". Once the adhesive is applied, the boned parts should beheld in contact until the part has developed handling strength. It is not necessary to clamp the parts unless movement during curing is likely.
Cure: Hysol 9436 can be cured for 5 days at room temperature. Curing temperatures up to 200°F can be used to reduce cure time. For example, 1 hour at 180°F will give complete cure.
Clean up: It is important to remove excess adhesive from the work area and application equipment before it hardens. Many common solvents and citrus cleaners are suitable for removing uncured adhesive. Consult with your supplier's information pertaining to the safe and proper use of solvents.
