If you need to create an almost indestructible 'rubber' mold you're looking at the right stuff. I've cast almost 20 bricks in the 2 molds I made from this stuff and after I clean them, they look like the day I created them. I went to my local Ace Hardware store bought one of those paint measuring buckets to mix A & B. Cleanup needs to happen quickly. The mixture has the consistency of something between maple syrup & honey. You can reseal the buckets at least once. Removing the brick I used to make the mold was challenging, I suspect I used the wrong release agent. Removing the bricks I made with the molds was not nearly as challenging. I sent Polytek an email on release agents and received an accurate and professional response within 24 hours. ## Features - Mix Ratio: 1A:1B - Shore Hardness: A45 - Pour Time: 30 min. - Demold Time: 16 hr. - Cured Color: Yellow ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075SGY738 | | Best Sellers Rank | #358,335 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #2,056 in Sculpture Molding & Casting Products | | Customer Reviews | 4.4 4.4 out of 5 stars (10) | | Date First Available | September 20, 2017 | | Is Discontinued By Manufacturer | No | | Item model number | 4336899669 | | Manufacturer | Polytek | ## Images ![Polytek 74-45 Liquid Polyurethane Rubber (16lb Kit) - Image 1](https://m.media-amazon.com/images/I/51bfn6IsCbL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ The stuff is damn near indestructible *by C***. on May 23, 2025* This stuff is amazing.
