Buy Smooth-On at FormX
Smooth-On is one of the world’s leading manufacturers of 3D modeling materials such as mold-making, casting and special effects materials, as well as industrial casting resins, adhesives and equipment. FormX is the 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.
Instructions
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.
