AeroMarine Products Black Urethane Polymer Casting Resin is a thin, very fast setting polymer used for casting parts for many applications.
It features a simple “one to one” mix ratio by volume.
It contains no fillers, has low odor, and cures to a deep black color.
Also, our black urethane polymer casting resin is easily painted.
AeroMarine Polymer Urethane Black Super Fast Casting Resin is a deep black color.
It sets to a hard polymer form and is very tough and impact resistant.
Our Black Casting Resin somewhat resembles PVC pipe when cured.
Shrinkage is usually unmeasurable.
10 gallon kit, smaller sizes available.

HOW-TO:

Mixing:

Both Part A and B should be at room temperature; 70F, before use.
Part B should be shaken prior to use.
Mix equal parts (1:1) by volume.
Measure in 2 separate clean plastic cups and pour into a 3rd clean plastic cup.
Stir immediately for 20-30 seconds, taking care to scrape the sides and bottom of the mixing
container.
To avoid excessive exotherm, mix small batches until you are familiar with using this material.
Since all urethanes are moisture sensitive, any filler used must be moisture free.
This product is not UV resistant when cured. If the finished piece is going to be exposed to direct sunlight, it needs to be painted or sealed with a UV resistant urethane varnish or automotive sealant.
Do not disturb the mold until the part is ready to be demolded.
Prematurely demolding parts can cause deformation, especially in thin areas. Work life and cure time can be significantly affected by several variables, including size of mix, part shape, ambient temperature, temperature of the mold, filler content and age of material.
For enhanced characteristics, you can post cure this resin at 125F for 2 to 4 hours.
Thin or detailed parts should be cured in their silicone molds or supported by other means.

Tips:

Always wear a respirator or self –contained breathing apparatus when working with urethanes
Do NOT spray. Our urethanes are only for pouring applications.
Urethanes are moisture-sensitive. Do not use paper, wax or wood mixing tools. Always re-cap container immediately!
Do not use on rainy or humid days.
Urethanes are very moisture sensitive and moisture contamination can give your casting resin bubbles.
Never mix less than about 3 ounces of product. It is much more difficult to get the correct mix ratio when working with very small amounts. These mixtures are exothermic, meaning they generate heat in order to cure. A mixture of less than three ounces does not generate much heat and can take significantly longer to cure.
Avoid mixing with drill motors. Mixing with electric drills can start the exothermic cure process and cause the product to cure in the mixing container. The paddles can also whip air into the resin causing air bubbles. It is always best to mix the material by hand, with a plastic mixing utensil.
If you use an aerosol mold release, let it dry first. A spray can of mold release contains a lot of solvents and propellants. These compounds need to evaporate off the surface so they don’t cause bubbles. Check the dry time of the mold release from the directions on the label. Once your casting resin is cured, you may want to wash it with a grease dissolving soap, like dish soap. This will help clean the surface of the resin for better paint adhesion.
Don’t vary the mix ratio. Unlike some polyester resins, altering the mix ratio to vary the cure cycle will not work with urethanes.
Mix in clean plastic containers. Paper cups and wooden mixing utensils may contain moisture which can adversely affect the urethane casting resin. Avoid waxed paper cups because the wax may melt and contaminate the resin.
How to avoid air bubbles- Air bubbles in urethanes are almost always caused by moisture. Do everything possible to avoid moisture getting into the mix. Replace the lids onto the containers promptly after use. Do not use the urethane resin during rainy days or times of high humidity. Avoid pouring against an unsealed water based product such as plaster or hydrocal. Seal plaster or hydrocal with a product like Krylon Clear Acrylic.
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, mix small batches to make the process more manageable.
Shake or stir well before use- The liquid components may settle in the containers during storage. Shake or stir the components separately and thoroughly before mixing. Let it sit a few minutes to let any bubbles rise to the surface after shaking the container.
Test- Consider the first piece you pour to be a test cast. The first pour will tell you about the cure time, demold time and other aspects of your project.
