I had a little time today and finally got a chance to try out the sample of Shell Shock resin from smooth on
This would be great stuff to make armor with and there are two flavors of shell shock Fast and slow
here is part of the tech bulletin
TECHNICAL OVERVIEW
Product Pot Life Demold Time Full Cure Color Durometer
Shell Shock™
FAST 3 minutes Variable
(mass sensitive)
1 hour at 3/8” (1 cm) thickness Beige Shore 85D
Shell Shock™
SLOW 8 minutes Variable
(mass sensitive)
5 hours at 3/8” (1 cm) thickness Beige Shore 85D
Here is what Smooth-On says about it
In response to customer requests for a “non-fiber filled” thixotropic plastic that will hold a vertical surface, Smooth-On has developed a product we are calling “Shell Shock™”. “Shell” because because the plastic can be used to form a shell and “shock” in reference to this product’s good impact resistance vs. other products on the market.
Applications - Shell Shock™is ideal for making fast, lightweight rigid molds and for creating silicone appliances and effects (use as a replacement for ‘stone molds’). You can also brush a “gel coat” into a rubber mold and back it up with rigid foam, creating a highly detailed lightweight casting. This product can be brushed onto styrofoam (polystyrol) as an impact resistant coating that can be sanded, primed and painted (minimum 3 coats recommended).
Shell Shock™ can also be used to make thin, lightweight rigid support shells (mother molds) to support brush-on rubber molds. It is mixed 1A:3B by volume and steadily develops thixotropy (becomes thick). Applied in thin sections, the mixture will hold a vertical surface. Like any brush-on material, if you apply too thick it will sag.
Pot life is on the fast side at about 3 minutes which helps with thixotropy, but you have to be aware of your working time. The material will stick to itself, so you can quickly build 3 to 4 layers to a minimum recommended thickness of 3/8” (1 cm) which is recommended for impact resistance. Time between coats is about 15 minutes depending on mass. Do not disturb the previous layer. Material cures in about 1 hour at room temperature (depending on mass). Gel time and cure time can be reduced with mild heat.
I used it to reniforce a Boba Fett Helmet I was casting and it started to warm up as I was mixing it, so I poured it into
the inside of the helmet and started to slush cast with it until it was too thick to move, then I used a brush
as far as I am concerned it work well as a brush on resin or for slush casting. I think it would work great with fiber glass cloth
by it self it has a shore 85D hardness.
It is mixed by volume not weight so a scale is not needed, I used 3oz dixie cups
so I mixed 9oz of resin and 3oz of hardner and in about two minutes I felt the cup getting warm.
I will try to post some video on my next test
