AeroMarine Products white urethane casting plastic resin 10 gallon kit yields ten gallons. It sets rapidly to allow you to produce many parts per hour. AeroMarine Products's white urethane casting resin is a 1:1 mix ratio, water-thin, low odor, with virtually no shrinkage. It has a 15-30 minute de-mold time, which makes it great for rapid production or prototype runs.
AeroMarine Products White Urethane Casting Resin is ideal for making figurines and decorative items. It can also be used to make prototype parts for automotive and industrial applications. Our casting resin cures to a tough, hard plastic, somewhat resembling PVC pipe. We offer urethane colorants for AeroMarine's white urethane casting resin. Alternatively, you can paint this casting resin with almost any paint (Krylon Fusion recommended).
If you have surface oil exuding from your casting, bury your casting in talc for 72 hours. Then, remove it from the talc. Wash your casting with water and liquid dish soap (like liquid Ivory). Dry casting thoroughly. Then, paint your casting. This method reduces the surface oil so that you can paint your casting.
**NOTE: Make sure that the
casting resin, tools, containers and ambient temperature are all at 70F before
you begin pouring the casting resin. If
you do not have everything at 70F, the casting resin will take much longer to
cure. Also, at temperatures higher than
70F, the casting resin will cure faster.**
AeroMarine's casting resin is available in other sizes; please check our other Ebay listings.
Once each side is measured and weighed in separate clean plastic containers, pour both A and B into a third clean plastic container for mixing. **Pour immediately after mixing!**

AEROMARINE PRODUCTS' BEST PRACTICES WHEN USING CASTING RESIN
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.
1) Because the sample is small, it is much more difficult to get the
mix ratio correct. 2) 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 with drill motors - Mixing with an
electric drill can cause a few problems. 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.
If you use a mold release, let it dry for a while -
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.
Don’t vary the mix ratio - Unlike some polyester resins, altering the mix ratio to vary the cure cycle doesn’t work with urethanes.
Mix everything twice - Mix the two components together very thoroughly in a clean plastic container, then
transfer the mixture to another clean plastic 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 clean plastic container, you are assured that everything is well mixed. Any unmixed
material stays in the first container.
**When using fast, water-thin casting resins, you may only have time to
mix it once, but since it is water thin it will probably mix fine in
Mix in clean plastic containers - Paper cups and wooden mixing utensils contain
moisture which may adversely affect the polyurethane. Avoid waxed
paper cups because the wax may melt and contaminate the resin.
Coloring our white casting resin. Add our urethane colorant by drop until
you get the color desired. NOTE: You will NOT get true black or true red with our white casting resin. For black, use
our jet black casting resin. For red,
use our crystal clear casting resin with our red urethane colorant.
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. This includes replacing the lids onto
the containers promptly after use as well as avoiding using the product
during rainy days or times of high humidity. Avoid pouring against an
unsealed water based product such as plaster or hydrocal. Consider
sealing plaster or hydrocal with something such as Krylon Clear
Acrylic. We stock an aerosol nitrogen blanket called “Extend-It” that can increase the shelf life of the urethane during storage.
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. A very
thin pour will take much longer to cure than a thick pour.
Shake or stir well before use - The liquid
components may settle in the containers during storage. Shake or stir the components separately before mixing.
Let it sit a few minutes to let any bubbles rise to the surface after
shaking the container.
Test - Always make a test 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
