Equinox Silicone Putty Products are new silicone compounds (platinum catalyst) that can be easily mixed and applied by hand to a variety of surfaces. Equinox Putty is mixed in equal amounts (1A:1B) by volume. Equinox 40 has a 30 minute pot life and 5 hour demold time. Shrinkage is low and cured rubber is exceptionally strong (very high tensile strength), durable and will resist high temperatures (for casting low-temperature melt metal alloys). They also resist cure inhibition. Applications include making fast mold impressions from almost any surface, orthotics/orthopedic, equine hoof repair, jewelry making and more.
