AeroMarine Epoxy #300/11 is a high performance epoxy used primarily for potting and encapsulating electronic circuits.
It is available either in black or clear amber. The black version is extremely popular for hiding proprietary circuitry.
It is also used as a coating to provide a dielectric barrier.
1/2 gallon kit (1 quart resin, 1 quart hardener); larger and smaller sizes available

HOW-TO:

Mixing:

Double Mix and Pour Method: Mix (1:1) by weight or volume
Mix the two components together in a clean plastic container for 2 minutes, then transfer the mixture to another clean plastic container and mix them again for another 2 minutes.
The theory is that the liquids clinging to the sides and bottom of the containers don’t get mixed well. By transferring the mixture to another clean container, you are assured that everything is well mixed.
To avoid excess exotherm, mix small batches until you are familiar with using this material.
DO Not mix the entire amount of resin and hardener together all at once. It will cure in your mixing container!

Tips:

Never mix less than about 3 ounces of product. When manufacturers design and test their resins they normally write the specifications for 100 gram batches, which is about 3 ounces.
There are two bad things that can happen when mixing a smaller batch. Because the sample is small, it is much more difficult to get the mix ratio correct. Also, these mixtures are exothermic, meaning that they generate heat in order to cure. A tiny batch does not generate enough heat to cure the resin properly.

Avoid mixing a large batch- At least until you are familiar with the product. The larger the batch, the more exotherm or heat is generated in the cure cycle. If you are casting a large part, consider mixing small batches to make the process more manageable. Thickness of the pour also affects the exotherm and cure speed. 3/8” is about the maximum thickness to pour most epoxies.

Do not vary the mix ratio- Old style polyester resins were catalyzed with a chemical called MEK.
You could vary the mix ratio to get different reaction speeds. Modern epoxies, polyurethanes, and silicones are different. They don’t use a true “catalyst”, but have a different kind of reaction
method. Varying the mix ratio usually results in a mess.
Mix and pour everything twice- Please see instructions above.
Mix in plastic containers. Paper cups contain moisture which may adversely affect the resin, especially polyurethanes. Avoid waxed paper cups as well.
Avoid mixing with drill motors. Mixing with an electric drill can cause a few problems. Frequently they don’t get into every corner of the mixing container. Also, if they spin too fast they can generate friction in the resin causing it to exotherm out of control resulting in premature curing. Powered mixing also can generate a lot of air bubbles.
Spraying- Do NOT Spray! Epoxies don’t spray well. They tend to run off vertical surfaces when sprayed. Addition of Cabosil will eliminate the run-off, but the epoxy turns a whitish color.
Clean-up- We use aerosol carburetor cleaner to clean up spills and messes. Otherwise just about any solvent will work, including acetone, MEK, toluene, xylene, and lacquer thinner.
Avoid regular paint thinner (mineral spirits). To clean hands, use “Fast Orange” hand cleaner available in automotive supply stores.
Test- Always run a test to determine the feasibility of your process. There are many unforeseen factors that can affect the outcome of your project. Running a controlled test may be inconvenient, but it can make the “Learning Curve” of processing these products much easier.
Aeromarine Epoxy 300/11 begins to gel in about 45 minutes, depending on the size of the batch and the temperature.
Apply to clean dry surfaces. Cleaning with acetone, alcohol, or MEK is recommended. Sanding or abrading surfaces generally increases bond strength.
You must accurately calculate the size of your project and the amount of epoxy that you will need!* If you are applying our epoxy over a porous surface, you may need to use more epoxy to obtain your desired coverage.
