Description

This one-component additive is designed to reduce the cure time of tin-cure silicone rubber compounds. The cure time reduction is proportional to the amount added, allowing the cure time to be shortened from overnight to just a few hours. It is added as a percentage of Part B before adding Part A. Note that the working time (pot life) is significantly reduced by the addition, and the rubber's viscosity will increase. Therefore, it is crucial to work quickly (mix, vacuum, and pour).

Instructions

Pre-mixing: Thoroughly pre-mix with Part B before adding Part A. Adding this will reduce the library life of tin-cured silicone rubber in proportion to the amount added.
Safety: Use in a properly ventilated area ('room size' ventilation). Wear safety glasses, long sleeves, and rubber gloves to minimize contamination risk. Store and use all products at room temperature. This product has a limited shelf life and should be used as soon as possible. Wear gloves and eye protection to minimize risk of contamination.
Measurement: All components must be measured using an accurate gram scale.
Steps:
1. Determine the total amount of rubber required for your application. Calculate the correct amounts of Part A, Part B, and additive in advance.
2. Weigh out the required amount of Part B.
3. Weigh out and add the required amount of additive as a percentage of the Part B. Mix Part B and additive thoroughly.
4. Weigh out and add the required amount of Part A.
5. Mix thoroughly, eliminating all color streaks from the mixture.
6. Pour mixture into a new, clean mixing container and mix again.
7. Vacuum material (29 h.i.g. mercury) as directed on the silicone rubber technical bulletin.
8. Pour rubber into containment field, let rubber rise over model.
Note: 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.
Important: Working time (pot life) is drastically reduced in proportion to the amount added. Viscosity of rubber will also increase. Mix, vacuum, and pour quickly.
