AEROMARINE PRODUCTS WHITE URETHANE CASTING RESIN POLYMER FAST SET 2 GALLON KIT!

Description: AEROMARINE PRODUCTS WHITE URETHANE POLYMER CASTING RESIN2 GALLON KIT AeroMarine Products' 2 gallon kit of white urethane polymer casting resin contains: 1 Gallon Part A and 1 Gallon Part B**Always wear a respirator or self–contained breathing apparatus when working with urethanes.**Do NOT spray! Our urethanes are only for pouring applications. AeroMarine Polymer White Casting Resin is a fast setting, low odor, "water thin", 75D durometer system. Our casting resin is ideal for casting decorative figurines, picture frames, antique replicas, and industrial parts. With a 30 minute demold time, it allows you to make rapid prototypes or production runs. AeroMarine Polymer Casting Resin is a white color when cured. We sell urethane colorants for this casting resin. You can also paint it (Krylon Fusion spray paint is recommended). AeroMarine casting resin sets to a hard polymer form and is very tough and impact resistant. It somewhat resembles PVC pipe when cured. Shrinkage is generally unmeasurable. We also sell urethane mold release to use with this casting resin. Check our other Ebay listings for silicones and related items. 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. At temperatures higher than 70F or with a large mixed amount casting resin will cure faster.

AeroMarine Products White Urethane Casting Resin Specifications: Shore Hardness: 75D Tensile Strength: 2390psi Temperature Restrictions: 140F Mix Ratio: 1:1 by volume Color: White Work Life: 3 minutes Demold Time: 30 minutes Once each side is measured in separate clean plastic containers, pour both A and B into a third clean plastic container for mixing.**Pour immediately after mixing!** Best practices when using urethane 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. When the sample is small, 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. Do not mix 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. You will end up with a sticky uncured part. Coloring our white casting resin. Add the urethane colorant to Part B before mixing in the Part A until you get the color desired. Please keep in mind that with a white base some colors may be muted. Mix in plastic containers. Paper cups contain moisture which may adversely affect the polyurethane. Avoid waxed paper cups because the wax may melt and contaminate the resin. Do NOT use wood implements when mixing urethanes--wood contains moisture as well. 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. Do not pour against an unsealed water based product such as plaster or hydrocal. Seal plaster or hydrocal with something like Krylon Clear Acrylic. You can an aerosol nitrogen blanket 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. You only want to pour in depths of 3" at one time. 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 very well before use The liquid components may settle in the containers during storage. Therefore, you must shake or stir the components very well 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 easier.
