Its clarity allows precise mold cutting and ensures complete cavity fill, making it ideal for intricate casting projects. Pourable and easily thickened for brush application, it delivers professional-grade molds with fast turnaround and durable flexibility. ## Description PlatSil 73-15 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a white translucent, Shore A15 rubber. The transparent nature of the cured rubber makes it a good option for molds that need to be cut after cured – because the model is visible, parting lines can be better determined. It is also very useful when casting intricate parts to ensure that the entire mold cavity has been filled with casting material. This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application. Notes: Contamination from sulfur (e.g., sulfur-based clay), amines, tin compounds, cured polyester resin, some paints and some silicone rubbers may inhibit surface cure of platinum-cured rubbers. For additional physical property specifications, refer to the Physical Properties Bulletin. Review: Love this product - Use it all the time, it is perfect for molds, especially if you want to see what you're casting while you pour. Great flexibility for release and it lasts for many casts. Review: Advertising is wrong - Link shows use equal amounts but it's by weight not volume according to directions inside box. I had purchased for a large project and the scale wouldn't go passed a certain weight so I had to pray it's work. It is pretty expensive. I used nearly both bottles which are smaller than appears in photo to make flower pot mold and tray. I would recommend using its for smaller projects. It is very thick. I had to cut mold to remove original pot I used to copy. ## Features - Mix Ratio: 1A:1B - Shore Hardness: A15 - Pour Time: 20 min. - Demold Time: 4-5 hr. - Cured Color: White Translucent ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0764JB16W | | Best Sellers Rank | #567,510 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #3,211 in Sculpture Molding & Casting Products | | Customer Reviews | 4.5 4.5 out of 5 stars (6) | | Date First Available | October 3, 2017 | | Is Discontinued By Manufacturer | No | | Manufacturer | Polytek | ## Images ![PlatSil 73-15 Platinum Silicone Rubber (2lb Kit) - Image 1](https://m.media-amazon.com/images/I/51YqOiDp7XL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love this product *by T***Y on September 30, 2025* Use it all the time, it is perfect for molds, especially if you want to see what you're casting while you pour.
