## Overview

Polytek PlatSil 73-15 is a platinum-catalyzed, two-part silicone rubber with a 1:1 mix ratio that cures to a white translucent, flexible Shore A15 rubber in 4-5 hours. 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.
