LET'S RESIN Silicone Mold Making Kit 0A, Extra Soft & Elastic Molding Silicone 70.5oz, Liquid Silicone for Mold Making Platinum Cure, Ideal for 3D Silicone Molds, Candle Molds, Soap Molds, Resin Molds

Good quality. Bubbles are almost noon existent, and when if there is bubbles, they disapate on their own. Easy to use, just a little hard to pour at first because of the bottle shape. It ran down the side a bit. Cured just fine, I left overnight. The thickens is perfect, soft and pliable. Clear enough to use UV resin without issue.

This silicone is very good quality mold making silicone. The 0A gets every little detail because it is a very soft silicone. Very easy to use it is a 1:1 by weight or volume. There are very small bubbles that comes out of this silicone when curing. This product is very well worth the price you pay.

Update*** my replacement for this item arrived Monday (it’s Wednesday) and I also received a second order that I purchased today. Both of them have expiration dates months past the first box and the boxes are a lighter shade of purple. Both orders arrived perfectly (it has been warmer temps tho) I used the replacement order yesterday and will use the new order tomorrow. Product is worth 5 stars. I think I may have just received some older product which made the original jugs more sensitive to the cold temps. Windchill alone was in the negatives. Giving 5 stars because I’ve used this exact product and know it works great. I always advise ordering 2-3x more than you feel you need. You will always need more. Product cures strong, tack free, and true to detail. Great value compared to local craft stores ** Warning though be cautious ordering in the winter. It can freeze. Make sure you’re going to be home when it’s delivered as there anre not packaging measures to prevent it from happening. And if it does freeze the seams of the containers are a little weak. Expansion isn’t good. Causes containers to crack at the seam. Blending in. Leaving a hot gooey mess if you don’t catch it frozen. On the company’s part ordering an exchange is fast and hassle free. However both ups and staples consider it a hazard if you try to return it with all the liquid just laying in a bag in the box. I get it. The solidified parts that were solid just gooey could stay but the liquid part can’t. If you ever have this issue (hopefully you don’t) Save yourself the hassle and PROPERLY dispose of the uncured part before trying to return. Or else you get sent home after driving 40 mins one way and have to do it all a different day. Understandable just inconvenient. Replacement arrive with 2 day shipping in perfect condition.

The 0a silicon is very flexible and durable. It picks up object details well. Bubbles from the mixing process released without applying negative air pressure. That was surprising to me because even though I stirred carefully, it poured full of tiny bubbles.

Haven’t had any issues with bubbles, yay! Fun to work with. Poured and went to bed. In the morning it was still a bit sticky but it cleared up after another day. I like the flexibility of this one a lot.

I've used three Let's Resin silicone mold making kits of varying hardness scales and this is my favorite. It comes with large mixing cups marked with clear measuring lines and big tongue-depressor type wooden mixing sticks that do the job much better than the popsicle sticks provided with the smaller kits. I measured the amounts carefully, using two mixing cups and allowing a tiny bit more in the cup I'd be pouring from, to allow for the residual amount that would cling to the cup and not pour into the mix. Within a minute of starting the mix the silicone started thickening. I used a model made of (dried) air dry clay coated with a thin veneer of acrylic paint and a day later I had a perfect mold. I was nervous removing the model due to some stretching required but the cured silicone stretched easily with no damage and the model slid right out without a release agent being needed. This was the smoothest mold making experience I've had yet and produced the best result. As a bonus, it seemed to be easier to clean up than the other kits I've tried, wiping the inevitable sticky residue clean off my fingers with a paper towel, without the repeated scrubbing the earlier mixes needed. I love this stuff!

I used this to create a Stop the Bleed trainer, and it worked great! The quality was exactly what I was looking for, and it met all my expectations. Highly recommend!"

These would worked perfect for our project i only wished it was bigger
