Platinum Based Silicone Mold Compounds

Platinum-Based Silicones... ... are two-component, addition-cure, platinum-catalyzed, high tear-strength, flexible mold compounds. (What a mouthful!) They are recommended as mold material for casting polyester, epoxy, polyurethane, wax and a wide range of other casting materials. They shrink minimally and, unlike the tin-catalyzed silicones, do not produce alcohol upon curing. The only problem with these rubbers is that they are extremely sensitive (not emotionally, but physically). The mix ratio is not particularly forgiving and sulfur is a killer.

Dragon Skin
Dragon Skin is high performance platinum cure silicone rubbers that is very soft, very strong and very “stretchy”. It will stretch many times its original size without tearing and will rebound to its original form without distortion.

Dragon Skin is suitable for many special effects application, especially animatronics where repetitive motion is required.

Dragon Skin is high performance platinum cure silicone rubbers that can be mixed 1A:1B by weight or volume and cures at room temperature with no shrinkage to a Shore 10A. Cured Dragon Skin is very soft, very strong and very “stretchy”. It will stretch many times its original size without tearing and will rebound to its original form without distortion.

Dragon Skin is suitable for many special effects applications, especially animatronics where repetitive motion is required. It is water white translucent and will accept pigments for creating color effects or for creating a paint that can be painted on to an existing Dragon Skin (or other) silicone surface. Because of the superior physical properties and softness of Dragon Skin, it is also used for orthopedic & cushioning applications. Dragon Skin has a pot life of 20 minutes and a demold time of 5 hours.

In A Hurry? Dragon Skin Q (Q = Quick) has a pot life of 8 minutes and a demold time of 75 minutes.(see below)

Platsil 71-10
This is the softest of all silicone rubbers, and captures the finest details and the deepest undercuts. Its fast set-up time allows easy instant molds. When doing molds, please be aware that temperature affects the curing time.

PlatSil® 71 Series RTV Silicone Rubbers are two-component, addition-cure, platinum-catalyzed, high tear strength, flexible mold compounds. They have tough knotty tear strength which make them especially valuable to the mold making industry. They are recommended for evaluation as mold materials for polyester, epoxy, polyurethane resins, waxes and many other materials. PlatSil® 71 Series Silicones are preferred because on curing, they don't shrink, they don't produce alcohol like tin-catalyzed silicones which can inhibit urethane castings, and they can be heat accelerated to speed the cure.

Rebound 25
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). 3 to 4 layers are 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.

P-90
P-90 is a high tear strength, platinum-catalyzed, RTV-2 silicone rubber. It is easy to mix and de-air, and will cure with virtually no shrinkage. The speed at which the rubber hardens can be dramatically accelerated with heat or with Pt Accelerator at room temperature. Addition-cure two-component silicone rubbers exhibit excellent chemical and heat resistance, but may show inhibition sensitivity. P-90 offers excellent release properties and is extremely useful for those applications where exceptional flexibility and tear resistance are required.

It is easy to mix and de-air, and will cure with virtually no shrinkage. The speed at which the rubber hardens can be dramatically accelerated with heat or with PT Accelerator at room temperature.

Addition-cure two component silicone rubbers exhibit excellent chemical and heat resistance, but may show some inhibition sensitivity. P-44 is supplied with 2 Activators: P-44A (1) is used for production molds, which P-44A (2) is used for casting clear parts. P-44 is extremely useful for prototype application where superior mechanical properties are required.

SORTA Clear
SORTA Clear is a premium water white translucent silicone (platinum catalyst) that cures at room temperature. SORTA Clear has a Shore A of 40 and features exceptional tear and tensile strength.

Rubber clarity is especially useful when extracting models via cutting. SORTA Clear rubber is ideal for making prototype, jewelry or other molds of any configuration where model visibility is important (i.e. extracting a model from the mold via cutting). Materials such as urethane, epoxy or polyester resins can be cast into SORTA Clear silicone without application of a release agent. Other materials such as wax and low melt metal alloys can also be cast into SORTA Clear. SORTA Clear can be pigmented with SILC Pig silicone pigments.

Platsil 71-40

Want a Clear Silicone? This is it! Shim lines and piece detail are easily viewed through this silicone, which makes cutting much easier. Many people are actually using this material as a casting medium for all types of clear flexible pieces. It has great resiliency and longevity. It can also be pigmented for seam identification or casting enhancement.

PlatSil® 71 Series RTV Silicone Rubbers are two-component, addition-cure, platinum-catalyzed, high tear strength, flexible mold compounds.
