Differences of Equinox™ vs. Poyo™ Putty (tin-catalyst)
- Price - Poyo™ Putty (tin-catalyst) is much less expensive.
- Inhibition - Because Equinox™ is a platinum silicone it is more easily inhibited by surface contaminants. However, this putty cures so fast that it resists inhibition better than slower cure platinums.
- You can join seams more easily with Equinox™, meaning that you can add new material to newly cured Equinox™ putty.
- Equinox™ putties are incredibly strong . . . much stronger than Poyo™ Putty.
- Being a platinum cure silicones, Equinox™ products can handle higher temperatures for casting low-temperature melt metal alloys such as tin and pewter.
- Equinox™ putties can be used to quickly repair platinum silicone molds or for making cut shim lines on Rebound™ 25, Body Double™ and other brushable platinum silicones.
These putties were originally developed for equine hoof repair applications, supporting a ligament in the hoof until it can heal. We are also selling these products to a number of orthopedic/ prosthetic fabricators for different applications. Jewelry makers use the putty to make fast mold impressions for casting high-temperature waxes.
Equinox™ 35 Fast has a pot life of about 1 minute with a cure time of about 7 minutes at room temperature (72°F / 23°C).
Equinox™ 40 Slow has a convenient 1A:1B by volume mix ratio, a 30 minute pot life and cures in about 5 Hours with a Shore hardness of 40A. Cure time can be reduced to under 1 hour with a heat gun, hair dryer or by placing the mold in an oven at 150°F/60°C. Like the other Equinox products, it has incredible physical properties and good heat resistance. It is much easier to mix and apply vs. our PoYo tin-catalyzed putty and is superior in every way. It is, however, more expensive.
Equinox™ 40 Slow offers enough working time to comfortably hand mix and apply to a model for making a mold. No surface preparation is required for many surfaces, however, this is a platinum silicone and inhibition is possible when applying over models made of sulfur clay and other surfaces that normally inhibit platinum silicone. When making a mold with any putty, developing an application technique to pick up detail from a model's surface and for marrying seams between sections takes practice.
