Smooth-On is one of the worlds leading manufaturers 3D modeling materials such as mold-making, casting and special effects materials but also industrial casting resins, adhesives and equipment. FormX is main distributor of Smooth-On products in Europe.
Silicone Thinner™ is a non-reactive silicone fluid that will lower the mixed viscosity of tin cure (condensation) or platinum cure (addition) silicone rubber products.
Silicone Thinner™ offers the following advantages:
- A lower mixed viscosity (A+B) means that the rubber will de-air faster when vacuuming.
- Mixed rubber (A+B) will flow better over intricate model detail.
- Silicone Thinner® will lower the ultimate shore hardness (durometer) of cured silicone rubber.
- Pot life (working time) is increased in proportion to the amount of Silicone Thinner® used.
Disadvantage: Ultimate tear and tensile strength are reduced in proportion to the amount of Silicone Thinner® added, however knotty tear properties of the Mold Max® series rubbers are unaffected.
Materials should be stored and used in a warm environment 23° C. This material has a limited shelf life and should be used as soon as possible. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.
*Silicone Thinner™ is added as a percentage of the total Part A+Part B rubber system. An accurate gram scale must be used. Weigh out and pre-mix required amount of Silicone Thinner™with Part A of silicone rubber before adding Part B. Mix all components thoroughly and vacuum as directed on mold rubber technical bulletin.
It is not recommended to exceed 10% by weight of total system (A+B).
Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.
