Eye forms for Silicone Busts

Eye forms for Silicone Busts

In our most recent tutorial we covered the process of making eye forms in resin. This is an important step in creating silicone busts or prop heads with open eyes. We started with a glass alligator eye. We molded the eye form with PlatSil FS-20. FS-20 was chosen for speed as it is a 25 minute demold. The original Eye form was released with Eject-it 33. We then cast TC-800 casting resin into the mold to produce hard plastic eye forms that could be embedded in our Monster Clay sculpture. The Monster Clay sculpt was originally poured from a PlatSil...

New FS-10 & FS-20 Silicone!

New FS-10 & FS-20 Silicone!

There is a new PlatSil silicone line: FS series! This is a new "Fast Setting" formula, hence the FS, and it has an incredible cure profile: 8 minute working time and a 25 minute demold. In addition to being fast, it is also very low viscosity and strong. Like many other silicones in the PlatSil line, FS series silicones can be thickened for brush-on applications. FS series silicones are also translucent so they may be easily pigmented with our silicone pigments for special effects applications. Here's a new video explaining the basic use of FS-20. You can find FS-10 and...

New TC-5050 Silicone!

New TC-5050 Silicone!

We now have TC-5050 silicone for mold making. This is a very firm, Shore A 50 platinum silicone that is ideal for prototyping applications. TC-5050 must be degassed as it is a very thick silicone system. You can find TC-5050 here on our webstore. As with our other Platinum formulas, remember that Platinum, or addition cured silicones are susceptible to cure inhibition on surfaces with contaminates such as sulfur, latex, and aloe vera. When in doubt, run a test cure in insure compatibility. Below are several excellent moldmaking videos featuring 5050 silicone for a variety of product development applications.

Group hand cast & plaster cleanup

Many of you have asked us to make a video on a group hand cast as well as a tutorial on clean up of a plaster/Hydrocal cast. In this blog post we cover the process of molding several hands together flat on a table. The first video explains the use of Genesis V alginate and plaster bandages to create the cast. This is a "lay-up" type cast wherein the alginate is mixed fairly thick and applied over the hands to create a mold that is about 1/2 thick. A cast like this captures 3/4 of the subjects hands leaving the...

Prosthetic Molds with TC-1630

Prosthetic Molds with TC-1630

We have just posted parts 1, 2, 3, and 4 of a new video series on silicone prosthetics. In parts 1 and 2 we cover the process of correcting and molding a positive and creating a negative mold with TC-1630 casting resin. 1630 is ideal for this process as it is very hard (~75D), heat resistant (suitable for baking foam latex), and does not shrink. 1630 is also moisture resistant so it works well with clay walls made of water-based clay. Part 3 covers the casting process using Super Baldiez cap plastic as an encapsulator and Deadened Gel-25 silicone inside...
