Lo usé para hacer un molde para aretes y el resultado fue el esperado, cumplió con mis expectativas. El único pero que le pongo es el precio pero aparte de eso lo recomiendo, muy buen producto.

I needed to make a few small molds to reproduce some NLA rubber gaskets and grommets for a classic car restoration. After reviewing some of the products available I decided on this silicone mold making kit because it a) contained the most silicone material for the price and b) included everything you need like gloves, measuring cups, even some stirring sticks. For my first mold, I mixed equal parts of the A and B components and let cure overnight (about 15 hours). The mold came out great; no bubbles or imperfections at all. For the mold of a second part, I again used the 1:1 ratio but tried to speed up the curing process by placing the mold mixture outside in direct sunlight. Not a good idea: while it cured within 2 hours, all the bubbles were still left inside the material! I repeated the mold making for that part by curing it at room temperature, and voila, a perfect mold again. Since then, I made molds for six additional parts this way, and each mold came out flawlessly. In order to cast the replica parts, I used 60A urethane casting compound. There were no issues releasing the cast parts from the molds, no release agent was necessary. I made at least 10 parts from each mold without noticeable degradation of quality.

Product worked exactly as promised. The quality of the mold it produced was outstanding. Initially I only needed the mold to last 4 pours but the loss of my initial successes plus the loss of the attempts I made using a challenging epoxy ment the mold got used 3 times that amount. The mold kept pushing out exact copies, no fraying or loss of detail. Very impressed.

Muy buen producto, cumple lo que promete, eso si, viene poca cantidad pero en general excelente.

Easy to use like advertised, decided to use this instead of a rubber molding to see if it works better, and so far it does, I was not expecting the short working time for it though, it starts setting within 10 minutes of being mixed properly so make sure you have what your molding ready to go. As others mentioned also it comes in smaller bottles then expected but it was fast shipping!
