I’ve used this product as the base for my custom handle pulls and drawer pulls that I make and sell on Etsy. It is extremely durable and cures very fast.
I love the results but the working time is just way to short. I was pouring out my resin in the molds that I had prepared and it was already turning white. And I wasted a lot resin.
Great product, although due to the opacity of the cured product, it is difficult to tiny or color to a deep color.
Best to brush inside of mold, prior to pouring mixed product.
No need to seal project, which is a huge plus.
While I'm still struggling to figure out what exactly I want to do with this, I love it. So far it's been really good for figurine molds and Christmas ornaments. BUT I don't like how it pours from the bottle because it runs down the bottle no matter how slow or fast I pour it. If you're reading this Let's Resin, please create an actual pouring spout. Please!
Absolutely love the product, it was my first time messing with anything like this, and I got it down easily! There was some tiny air bubbles but that’s because I forgot to shake the mold. The texture feels so nice (maybe even expensive hehe) and the white color is beautiful. I added ink to mine to try different looks, I’m very pleased with the results. Had about 3-4 mins tops because this does start working FAST. And boy does it get hot.. durability seems strong, but we’ll see in the long run with my plants 😉 my only complaint is that after making 3 pots (see photo and video) I’m almost out of product.. I have enough for maybe one more large-ish pot or 2 small ones. Still cheaper than buying them for an average $10 a piece, but not by too much tbh. Attempting to find a larger size for possibly cheaper price cause I do love making pots myself
This stuff is amazing! Cures very fast but gets super hot while curing. Wish it came in bigger sizes and that it had some sort of spout to prevent drips
Absolutely love this product. 10 minute cure what a dream. And you can see your tattoos really good on white.. I've been able to make some really cute items. Looking forward to making more.
I don't know why I haven't tried this sooner! This is so easy and it only takes about 10 minutes to cure! Part A and Part B are very liquidy and it's great for putting into molds that have small intricate detail cuz it gets in all the little crevices that regular epoxy sometimes misses or makes a bubble. It stirs up quickly and you can feel it heating up so you know it's about ready you pour it into the mold and within five minutes it starts turning white. It does heat up very hot and it is a little scary at first but it doesn't flash cure. Yes it does turn out white I did try putting blue micro powder in and it does work.
Works awesome
I'm new especially to Polyeurathane resin - things you need to know - 1) This will dry WHITE and opaque - I made a nice collage and covered it and very quickly realized it was going to cure opaque 2) The mix time is also very quick. Your working time is 2min so try to set everything out first. I have been finding the coloring process a little tricky. For the most part, in my experience, it seems to work as promised. I just give it a little more time to process than indicated. I like to give it a couple of hours.
My first time ever trying resin. Worked great!
Easy to use, produces a good product.
Works well. You have to be fast but gave a great white backing.
Good resin. Easy to mix and use
Easy to use but the weight of finished product is feather weight
Wonderful quick cure resin but not happy with the way it pours from bottles. Very messy pour.
El producto es muy bueno un 9👍
Ya gotta be quick
I used to use generic craft store resins and compared with this brand . The difference was very clear. It’s low viscosity and gets every tiny detail . 10/10
If you want pure plastic this is your option. I liked the fact that the replica was great-but I had difficulty in hand painting it. It is expensive. Very short acting resin. Before I could pour it it was drying and thick. Turns white so coloring it before mixture pour may be the way to go. I would not buy it again. I used it because i poured a Plaster of Paris figurine and it was heavy and thought that my canvas wouldn't be able to handle the weight. A better option was buying a wood canvas/wood glue.
Bottle a arrived with some minor leaking. Otherwise the product works as expected
This was my first time of using this resin and it turned out great. No bubbles and a smooth, even surface and so fast to set!
