PRELIMINARY TECHNICAL DATA SHEET
V-3040 is a two component, high strength, addition cure, room temperature or heat accelerated cure silicone
rubber compound. Designed specifically for moldmaking, It is an ideal rubber for reproducing intricate detail,
and maintaining close tolerances. This material has IMPROVED POLYURETHANE resistance. It is an
excellent choice for pattern shop, model shop and stereolithography service bureau moldmaking or tooling
applications.
