HOW-TO:

Mixing:

Mix the resin and hardener in equal parts by weight or volume. AeroMarine Products 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 or denatured alcohol is recommended.
Sanding or abrading surfaces generally increases bond strength.

Tips:

Never mix less than 3 ounces of product. There are two things that can happen when mixing a smaller batch. It is much more difficult to get the mix ratio correct. 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. 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.
Don’t vary the mix ratio. Varying the mix ratio results in a mess.
Consider mixing everything twice- especially if you are a beginner. Mix the two components together, then transfer the mixture to another container and mix them again. 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 container, you are assured that everything is well mixed.
Mix in plastic containers. Paper cups contain moisture which may adversely affect the resin, especially polyurethanes. Avoid waxed paper cups as the wax can melt and cause contamination.
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. If the paddle spins 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.
Storage- Epoxy resins tend to freeze at fairly high temperatures, sometimes at 50F. If allowed to freeze, “epoxy ice” can form in the container. It usually looks like swirls of white stuff suspended in the resin. It can be reconstituted by warming to 120F for a couple of hours- or you can use the “non-ice” part of the epoxy.
Spraying- Do not spray this material.
Clean-up- Use acetone and denatured alcohol to clean up spills and messes. To clean hands use a pumice hand cleaner available in automotive supply stores.
Test- Always make 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.
