Equinox™ Line Of Platinum Silicone Putties TECHNICAL BULLETIN MSDS

Differences of Equinox™ vs. Poyo™ Putty (tin-catalyst)

1. Price: Poyo™ Putty (tin-catalyst) is much less expensive.

2. 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.

3. You can join seams more easily with Equinox™, meaning that you can add new material to newly cured Equinox™putty.

4. Equinox™putties are incredibly strong . . . much stronger than Poyo™ Putty.

5. Being a platinum cure silicones, Equinox™products can handle higher temperatures for casting low-temperature melt metal alloys such as tin and pewter.

6. 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.

You can also make fast mold impressions from almost any surface. The rubber will reproduce perfect detail, but you have to work fast.

TASK™ 7 & TASK™ 8

TASK 7 TECHNICAL BULLETIN TASK 7 MSDS TASK 8 TECHNICAL BULLETIN TASK 8 MSDS

Moisture Resistant TASK™ 7 - Urethane resins, in general, are moisture sensitive. During the summer months, we receive reports of moisture reaction from people other resins, especially in the southern United States and other parts of the world where humidity is high. TASK™ 7 was developed to resist high humidity environments where other resins might bubble or foam. It has a 7-minute pot life and 30-minute demold time, depending on mass. It cures to a Shore 70D with good physical properties and can be used for a variety of general casting and prototype applications .

Heat Resistant TASK™ 8 - Urethane casting resins are generally not known for high temperature resistance.TASK™ 8 is a urethane resin that resists temperatures up to 265° F /130° C. Like any high temperature resistant urethane resin, you need to heat cure this product according to the cure schedule on the technical bulletin.

TASK™ 8 features a convenient mix ratio, low viscosity and has good physical properties. It has a 2.5 minute pot life and cures to an 80D. TASK™ 8 is good for making heat resistant prototype and mechanical parts.

Improving Heat Resistance Of Some Other Smooth-On Resins - As you may know, post curing any Smooth-On liquid plastic or rubber at 150°F/65°C for 4 to 6 hours will improve the overall physical and performance properties. Some Smooth-On plastics however, will experience dramatically improved heat resistance by step-heat-curing them at higher temperatures.
Which Plastics? Smooth-Cast 320, Smooth-Cast 385, Task 6, Task 21 and C-1508.

What Cure Schedule? After allowing the casting to fully cure at room temperature, post-cure in the silicone mold at 175°F / 80°C for 2 hours, followed by 100°C. Remove mold from oven and let cool before demolding.

Important: 1) At these temperatures, you can only use silicone rubber as the mold material, and 2) The plastic softens when exposed to these temperatures and will distort if you try to post cure it outside of the mold.

Ure-Fil 7

Ure-Fil™ 7 Added To Urethane Resin Provides Dimensional Stability, Economy & Improved Flame Resistance
As many of you know, there are literally hundreds of powder fillers available that you can add to casting resins. You can attain a variety of effects with different fillers.

Currently, we sell Ure-Fil™ 3 which is a crushed ceramic. We also offer Ure-Fil™ 5 for customers looking to attain a woodgrain finish in their castings.

Our latest addition is Ure-Fil™ 7, which is a fine powder that mixes well with urethane resins and can be added by volume to attain different effects and properties.

Urefil 7 will improve the dimensional stability of some materials (reduce the shrinkage rate of some resins, for example). Urefil 7 can also added to materials to make them flame-resistant. And like most fillers, ATH will lower your cost per casting in proportion to the amount added.

Be careful of
the amount of Ure-Fil™ 7 you add to a resin because cured castings can become brittle. The maximum amount of that you could add to a resin before compromising the physical properties of the cured plastic would be 1A to 1B to 2 Parts Ure-Fil™ 7.

A mix ratio of 1A to 1B to 3 Parts Ure-Fil™ 7 will make the plastic trowelable, but the cured plastic will also be brittle.

Rebound™ 25 Brushable Silicone Rubber TECHNICAL BULLETIN MSDS

Rebound™ 25 is an easy-to-use platinum-cure silicone rubber that self-thickens for making brush-on molds of almost any model. Mixed 1A:1B by volume (no scale necessary), Rebound™ 25 can be applied with a brush or spatula to vertical surfaces without sagging and will cure with negligible shrinkage to a soft, flexible rubber (Shore 25A) that is incredibly strong.

Advantages Over Urethane Brush-On Rubber:
(a) Rebound™ 25 will not stick to most surfaces, so surface preparation is minimal, (b) Two liquids that mix easily together, (c) Rebound™ 25 sticks to itself readily, even when cured, meaning that you can add more material at any time.

Three to four layers is all that is necessary to make a strong, durable production mold for casting wax, gypsum, concrete or resins (urethane, polyester, etc.).

And because Rebound™ 25 is a platinum silicone, it will last for many years in your mold library. Applications include reproducing sculpture, architectural restoration, making candle molds, etc.

Ecoflex Series™ TECHNICAL BULLETIN MSDS

Ecoflex™series of platinum-cure silicones are softer versions of our popular "Dragon Skin" silicone. There are currently three products available within the Ecoflex™ line; Shore 5A, 00-40, and 00-30. For those of you who have never heard of the "double zero" scale before, the hardness of these products is below a Shore A0.

These products are easy to use and cure at room temperature without a "tacky" surface. Ecoflex 5 is made to be a very fast system, for specific "made-in-place" prosthetic cushioning applications. This product is only available in 400ml tubes.
The Ecoflex™ 00-30 & 00-40 products are used for similar cushioning applications but are also used for making prosthetic appliances.
Sil-Poxy™ TECHNICAL BULLETIN MSDS

Many of you know that silicone does not stick to many surfaces, which is why silicone rubber is preferred by so many for a variety of casting applications. Silicone will stick to silicone, but ensureing a permanent bond is never guaranteed, which is why we are introducing Sil-Poxy™. It is a one-component adhesive that can be used wit either Mold Max™ (tin) or Smooth-Sil™ (platinum) silicones. It is easy to apply and bonded parts can be handled in less than an hour. It works great on torn silicone molds and a variety of prosthetic and animatronic applications.
Alja-Safe™ TECHNICAL BULLETIN MSDS

Alja-Safe™ is a new addition to the Smooth-On family of "Life Casting" mold making materials. Alja-Safe™ alginate is easy to use and cures quickly - good for making "temporary" molds of the face, hands and other body parts.
In addition to being an exceptional body molding material, Alja-Safe™ alginate does not contain free crystalline silica (a known carcinogen*). Alja-Safe™ also captures detail better than other alginates, giving you a more accurate reproduction of your original.
Alja-Safe™ is mixed, equally, 1 part water to 1 part Alja-Safe™ and, like all alginates, is best mixed with a Squirrel™ Mixer or other mechanical mixer. Working time is 7 minutes and demold time is about 10 minutes (assuming a water temperature of 80°F / 27°C). Colder water will give a longer working time, warmer water will cause the alginate to cure faster. Alja-Safe™ reproduces fine detail and makes and excellent temporary mold - good for one or two reproductions of any body part. You can then cast plaster, Matrix™ NEO™ (polymer modified gypsum) or Smooth-Cast™ 300Q fast urethane resin into the mold to make a reproduction.
* The International Agency For Research on Cancer (IARC) has rated free crystalline silica a "Group 1" carcinogen, known to cause cancer. Alja-Safe™ alginate does not contain free crystalline silica
Body Double™ (Certified by the Arts & Crafts Materials Institute)

TECHNICAL BULLETIN MSDS
Smooth-On’s New Body Double™ is a silicone rubber that can be applied directly to the skin to make fast and lasting molds of the face, hands and other body parts. Available in “Standard” or “Fast” Set, both are mixed 1A:1B by volume, cure quickly with high tear strength and will reproduce perfect detail from any original model - far better detail than any alginate.
Cast As Many Times As You Want - You can cast anything into a Body Double™ mold and make many castings from a single mold - not just one.
Save On Material And Labor Costs - With Body Double™, you use less material and can go right from the body to casting. By not having to make a plaster positive from your alginate mold, clean it up and re-mold it, you actually end up saving money.
What Is The Difference Between “Standard Set” and “Fast Set”?
Standard or Fast Set - The rubber is the same. The only difference: working time (pot life) and demold time.
Body Double™ "Standard Set" for larger surface areas - torso, full-leg, etc. Working time of 5 minutes and a demold time of 20 minutes - at room temperature.
Body Double™ "Fast Set" for fast turn around. Working time of 90 seconds and a demold time of 5 minutes - at room temperature.

Both stick to themselves readily, so more material can be added at any time. Important - Body Double™ is temperature sensitive - the warmer the material and environment, the faster the material sets. Use At Room Temperature!
