Entropy Clear Casting Epoxy Resin (CCR) is a low-viscosity, pourable liquid epoxy designed specifically for casting, embedding, and coating applications. It exhibits low color, excellent air release, and UV stabilizer technology for crystal clear products with excellent color stability.
All Entropy systems employ the lowest sensitizing ingredients for increased user safety, which makes CCR a great eco resin for any art or hobby project. CCR is available in two hardener speeds. Slow hardener (CCS) is best for applications greater than 1" thickness due to low exotherm. Fast hardener (CCF) should ONLY be used for low build casting applications with thicknesses BELOW 1" for long pot life and low exotherm. Both systems have a bio-content greater than 30%, & can be modified with epoxy compatible colorants and fillers.

Why Use Clear Casting Super Sap® Epoxy Resin?
Super Sap formulations, as opposed to traditional epoxies that are composed primarily of petroleum-based materials, contain renewable, biobased materials sourced as co-products or from the waste streams of other industrial processes, such as bio-fuels and wood pulp production. The benefits of these natural components are exceptionally high adhesion properties and excellent elongation.
Three Easy Ways to Measure Clear Casting Epoxy Resin and Hardener
By Volume: 2 parts resin to 1 part hardener.
By Weight: Varies. Check Technical Data Sheets for specific ratio.
By Pumps: The calibrated Entropy Pump Set (sold separately) measures the exact 2:1 ratio by volume with no mess or guessing about correct measurements, so you get a proper cure every time. Pumps can be used with the 2:1 High Bio-Based Epoxy Resin (ONE), Clear Laminating Epoxy Resin (CLR), Optically Brightened Laminating Epoxy Resin (BRT), Compression Molding Epoxy Resin (CPM), and Clear Casting Epoxy Resin (CCR) systems.
Measuring & Mixing Notes: For best results, use a scale to measure the two components by weight (within 5% of the recommended mix ratio). Always mix product thoroughly for at least two minutes. To ensure complete mixing, scrape all surfaces of the container.

Safety and Handling Information
Despite the natural derivation of Entropy resin products, exposure to these materials represents hazards typical of all epoxy resins. Exposure should be minimized and avoided through the use of proper personal protective clothing & equipment, and appropriate manufacturing controls. All persons who use, store, or transport these materials should understand proper handling precautions and recommendations, as stated in the SDS (safety data sheets).
What hardener do I buy off of the site here for this epoxy resin?
Entropy Super Sap CCS Clear Casting Slow Hardener or the Fast Hardener.

What is the shelf life of the resin and either of the hardners after they have been opened and a portion used?
Shelf life is quite long after it's been opened, at least 2 to 3 years if stored between 60 and 90 degrees.

what can you use to color the resin or tint it?
Epoxy / Gelcoat Coloring Agents listed on our website.

What is the coverage of this item? I neede to determine how much to buy.
This is casting resin, it depends on the thickness and the volume. You will need to do the math to calculate how much volume you have. Length x width x debth = Cu Ft. There are 7.47 cu ft per gallon.
What is the earliest I can demold to start sanding and polishing and also is it safe to use it in a small apartment?......would it fill the apartment with a certain odor?Alex from MÂ¥Ã‹_Â¥Ã‹_Â¥Ã‹_xico
I let mine cure for 16 hours and the post cure it for 6 hours at 170 degrees in a toaster oven. let it cool to room temperature and then its ready for finishing.
Hi, yes it is safe to use in the apartment as it is practically odorless and non-toxic. I use it from the home studio too. Demolding time depends on the hardener you're using. With my experience slow one needs about 4 days to get to the stage when it can be sanded, but to reach complete hardness it needs 1-2 more days. Fast hardener works much quicker and in about 24 hours your casting will be rock hard.
does it include the hardener?
There are two parts you need, A and B. Generally they are sold together. The smaller of the two is the hardener (its a one to 2 ratio). But I think you have to click on each of them separately when you order. You should see them listed separately in the order form (shopping basket).
How many hours does it take for the entropy ccr resin to cure? Cure as in to touch and handle and the cast out of the mold?
I generally work with entropy in the 1 - 6 pm timeframe.In the rare times I've used it in the morning, it is not dry to the touch by the time I leave my workshop at 6.However, anything I do in the afternoon is dry to the touch when I come in the next morning. And I can release it from the mold, etc. BUT, it is not really cured at that time. If pieces come into contact with each other, they may stick together, or a piece may adhere to the surface they are left on. But they can easily be knocked apart again. I think you need 72 hours for a full cure. But the "soft" interim time is good for shaping, sanding, sticking pieces together with more Entropy, etc. This all assumes you are mixing by weight, not volume.Hope this helps.
why is it cheaper to buy 4 16 oz epoxy resin than 1 gallon?
16 ounces is not 1 quart....it is a pint.multiply by 8 not 4.
Can I use this resin to make copper, brass, and sterling jewelry? Can I use tape for the bottom? I will have metal sides.
Yes, you can make jewelry....I have done so. I'm not sure how you are combining it with the metals but you work with it as with a bead or glass. It is fairly easy to ream. You can set findings with any glue or if careful, when casting the resin itself. I'm not sure how you are using the tape. Tape sticks to resin after it is hardened just fine. It should come off clean as well.
con i use it for coating art work, is it crystal clear?
Hi, I'm an artist who has been working with this resin for over a year. I like the product very much but I want to be careful in replying to your question.First the easy one....it is crystal clear, like glass even.The notes to the product do say that if unused, over time it may start to discolor...shelf age can be an issue. I currently have 1/4 of the material left after 10 months and have noticed that Part B is starting to look a little cloudy but it sets crystal clear. Anything I've made has retained its clarity.Now the more difficult one: coating art work. I have only used this material in mosaic work and 3D molds. I see no reason it couldn't be applied to the surface of an art work. If you could get it to set it would provide a very high gloss glass-like finish. Is that what you want? But depending on the art work, you may have some problems (is this an oil painting, a ceramic, a metal sculpture?) Here are my key concerns. 1. getting a smooth even coat. This material takes many hours to cure. In that time, it seeks the lowest physical level it can find. And it's ability to seep through the tiniest cracks is incredible. I made the mistake of framing a flat surface with duct tape and wood stretchers. I thought the spray release I used would be enough but hair line leaks caused the work to become thoroughly sealed on the table cover.One of its oddities is that it beads. I've only done this on rubber mold material, but resin won't hold a really thin layer on rubber. I have tried to barely cover a surface, creating a nice even layer and a few minutes later it has separated and formed little pools of itself that are thicker. Molecularly, I suspect it has a minimum level of thickness that is more than a coat of something like shellac or varnish would be. Also if spread on a vertical surface it will not stick but will run off and pool on the floor. 2. Bubbles. They must be removed... I am running out of space...want more info, send a follow on question.
The distributors went above and beyond to get me this product on time for my senior art show! It worked perfectly, and was exactly what I had ordered, arriving in a timely manner. Thank you for your accurate and efficient service, and for your friendly manners!
