A to Z Jewelry Tools & Supplies
1KG Castaldo® LiquaCast RTV (room temperature vulcanizing) is a two part liquid silicone mold rubber that sets in 90-120 minutes, has zero shrinkage and is strong so it can be used 100's of times over.
Because of its liquid state before setting and that it is poured into a mold frame without any pressing needed, LiquaCast RTV is ideal for impressions of delicate models like from CAD or objects from nature such as leaves, flowers, etc.
