## Description

Enduro SOFT is a soft polyurethane rubber casting resin with a highly flexible feel. Even with its softer feel it still has the toughness and durability of the Enduro line of Simple Resin products. Enduro SOFT is naturally light in color which makes it perfect for adding pigments and powders leaving you with the ability to create the exact rubber part that you’re looking for.

Review: This stuff is great! - I am a complete beginner at urethane molding. I needed to mold some underwater cable splices which have to be absolutely waterproof. This seemed like the stuff to use. It worked great! See the results in the attached pictures. I made a mold out of High Density Polyethylene (HDPE). Pictures of the mold are attached as well. I did some reading and followed the directions. It is important to mix well, and avoid all moisture or moisture bearing materials (like wood). The coloring was done with mica powder (only a small amount needed). The Mica flakes are what gives the urethane its mottled appearance The result was waterproof, tough, and flexible. I just bought some more of this stuff for another project. It is easy to use - just mix (thoroughly) and pour in one mold hole until it wells up in the other. In the picture the gray one has just come out of the mold and hasn't been trimmed yet. For HPDE you don't need any mold release spray. I had added jack screws in the mold to force the clamshells apart, but this was overkill. The mold comes apart easily. I did notice that the urethane sticks tenaciously to polystyrene. All the polyethylenes should work well for solid molds.
Review: Impressive! - I'm super impressed with the durability of this rubber. A bit harder than expected. Easy to mix. I ran it through a vacuum chamber before molding. Tints easily with epoxy pigment. Do not use dye. It will compromise the rubber.

### ⭐⭐⭐⭐⭐ MIX THE DAYLIGHTS OUT OF THIS STUFF
*by P***P on March 7, 2024*

You have a 5 minute working time with this stuff at room temperature, I used a cordless drill with a paddle in it as my mixer, do this for at LEAST 45 seconds. Start your drill submerged and keep it submerged for the duration of the mix, and you won't get any bubbles in this stuff. Mica powders are compatible and produce striking colors in the resulting part. Your results if you follow instructions above is a mindbogglingly strong casting after about two hours. I have yet to see a soft urethane this strong.
