PoYo Putty 40 is a two-component mold making silicone (tin catalyst) that can be mixed and applied “on site” – directly to almost any model. PoYo Putty will hold any vertical surface and capture even the finest detail - perfect for making strong rubber molds that can be used within minutes. 

 PoYo Putty has been used to make molds of valuable antiques and archeological models and can be used to make fast molds of sculpture, prototypes, candles, picture frames, coins, etc. You can cast wax, gypsum and a variety of resins into PoYo Putty molds.

Features

• Use Less – Do More: Because PoYo is applied as a thin layer, less material is used, saving you money. Molds are also lightweight, making them easier to handle.
• Pot life and cure time can be adjusted (faster or slower) by varying the amount of Part B catalyst.
• User Friendly - PoYo™ Putty can be measured and mixed by volume (no scale necessary).
• It will stick to itself and other silicone rubbers, giving the user many application options or for using as a silicone rubber repair material.
