JDictionSilicone Mold Making Kit, 5lb(80oz) Super Elastic Liquid Silicone for Molds Making, Fast Cure Soft Mold Making Silicone Rubber for Casting Resin Molds/Silicone Molds/Candle/Soap Molds

I've wanted to make silicone molds for years and always found the material to be too expensive. This seemed to be the right price. I've now created multiple molds with this material and have had no issues whatsoever. The molds came out bubble-free and were successful in casting plaster.For ease-of-use and to use less material, this is how I used this kit:1. Place a container on a digital scale, zero-out (tare) the scale.2. Pour part A into this container, take note of its weight.3. Pour part B until the scale reads two-times what it did for Part A.4. Stir slowly with the included popsicle stick. For a standard soup can, I would make one rotation in 4 or 5 seconds.While stirring, scrape the sides and touch the bottom of the mixing container periodically to ensure all material is incorporated into your mix. Don't remove the stirrer or go fast as it can incorporate bubbles.Finally, pour the silicone mixture very slowly into your mold box but not on the item itself. It is less likely for air bubbles to be trapped by pouring to the side of the item instead of onto it. I held my soup can around 2 feet high and allowed a very fine stream to flow into the box. The overall pouring time was between 3-5 minutes.I didn't use the included silicone measuring cups and feel it is unnecessary for what I'm doing, as well as a potential waste of material (material remains after you pour it, and this stuff comes with a premium).It was too cool outside here for proper curing (less than 70F), so I took a small space heater which measures about 6" tall, placed it in front of the mold, then laid a box over everything, with one side of the box resting on top of the heater. This allowed the temperature inside the box to get quite warm (80-85F - ish), and it cured no problem.Finally, I was able to pour plaster of Paris and cast my pieces which came out lovely. No bubbles in the final plaster product. Quite satisfied with the results and this product.

Since this is the first time I've ever cast a silicone mold, I can't really compare it to other products. I can, however, express how pleased I was with the results. I was making a 2-part squish mold of a very thin, highly textured model part reproduction, & the JDiction silicone flowed beautifully around the details & perfectly filled some tricky holes where there was a concern about catching air bubbles. Though I did degas the silicone before pouring, any bubbles that may have been initially trapped by the pour rose to the surface immediately & popped & leveled on their own accord with only a couple of light taps to the side of the mold case. Further, I was pleasantly surprised at how cleanly the first part of the mold separated from the sculptex clay I used to build up the mold -it just peeled away cleanly & with no hassle. Using a very thin brushed-on coat of vaseline as recommended made separating the second part of the mold equally easy. Altogether, the resulting mold was perfect -no bubbles whatsoever, exact surface detail/texture- & after 48 hours with Amazing Clear Cast epoxy resin in a pressure pot, the flexibility of the silicone made separating the textured surface a breeze with no tearing of the mold or distortion of the part even though ACC resin remains very flexible when first demolded. Needless to say, I'm very happy with this product & have no reservations about recommending it to other first time users out there.

Considering the price and the amount you're getting, the quality is excellent. The cure time is quick, taking only 5-7 hours, making it very convenient, and it molds with great detail. Once fully cured, it’s hardly sticky at all, and the flexibility is impressive.

EDIT:Excellent customer service. Increased my rating merely due to that.-----------------------Listing the product by weight can be misleading - I don't know about others, but I find it terribly difficult to figure out what 2lbs or 5lbs of liquid means in terms of volume. This is 2, 40oz jugs for the 5lb kit.The mix of 1:1 by weight (not volume) is no problem - but realize [B] is lighter than [A] --- That means You'll run out of [B].. and still have quite a bit of [A] left over. You can't fully take advantage of the product size. If [B] is Lighter than [A], then [B] should be in a larger container to compensate for the weight disparity. You'll end up with approximately 200-300 grams of [A] left over.. with no [B] to mix with it. That difference could be easily calculated and the manufacture could included an additional 200g-300g of [B] - thus making ALL the product even (by weight) and entirely usable.As for the quality, it's good. I have ZERO complaints about the actual silicone this kit produces. Silicone cured relatively quickly, wasn't overly sticky once cured, retained shape well even after stress, and the containers didn't leak. Although the mix is by weight, the pumps provided do make it a tad easier than lifting jugs to pour and preventing drips.My only real gripe is the wasted 300g of [A]. Kinda *feels* like its throwing money away - albeit, not much.

Good quality

Pretty darn good silicone. Set up fast and easy to mix and work with. I'll buy this when I need to make a mold.
