Product Details
VST Series – High-Performance Platinum RTV Silicone
Exceptional strength. Outstanding versatility. Economical pricing.
Factor II's VST (Versatile Silicone Technology) Series delivers our highest physical properties in an RTV silicone at our most economical RTV price point. These translucent, platinum-catalyzed silicones combine exceptional tensile strength, tear resistance, and elongation with convenient room-temperature curing.
With tensile strength up to 1,095 psi, tear strength up to 130 ppi, and elongation up to 660%, the VST series provides outstanding durability and flexibility for mold making, casting, prototyping, and specialty silicone fabrication.
The versatility of VST comes from its interchangeable catalyst system. A common silicone base (Part A) can be combined with different Part B crosslinkers to achieve a variety of cure times and hardness levels, all using the same convenient 10:1 mix ratio by weight.
