BBDINO Super Elastic Silicone Mold Making Kit, 21.16 oz Liquid Silicone Rubber, Ideal for Casting 3D & Food Molds, Jade Green

Buen producto

I find this silicone to be very flexible, the softest I have ever used. It was cast into a 3D printed PETG mold with no trouble. I debated if it was going to have a negative effect on resin part casting, but it worked very well for some smaller parts I make. I also use a pressure pot for the resin curing and didn't have trouble with the mold changing shape, even though I have these designed to use the absolute minimum amount of silicone (not enough silicone lol). The geometric shape being cast has torn a firmer "brand name American" blue silicone much easier, likely due to the small opening I use to remove the part. I use a sulfate free clay to hold my parts in the mold and there was no reaction to the clay.I did degass the silicone in a vacuum chamber and had absolutely no air bubbles, even after using a plastic mixer on a drill to combine the two parts equally. Working time is dramatically increased when ambient air temp is 18 degrees with cure at 5-6 hours. At the recommended 25 degrees, it was cured in 2 hours as they note. At both temps it was easy to use the vacuum chamber.I made 4 molds, three times, using different temps between 18–25 degrees and all succeeded. Cast 48 parts with no flaws or failures at all.

Vorteil: Das Silikon entlüftet sich sehr zuverlässig selbst und ist extrem dünnflüssig. Dadurch läuft es in wirklich jede noch so kleine Vertiefung und bildet feine Details sauber ab.Nachteil: Genau wegen dieser Flüssigkeit kann es auch leicht aus winzigen Spalten herauslaufen, weshalb eine absolut dichte Form nötig ist. Die Aushärtung dauert außerdem länger. Man muss wissen, worauf man sich einlässt, bekommt dafür aber eine sehr hohe Abbildungsqualität.

Good
