SRTM Thickening (Thixotropic) Additive
The SRTM Thickening Additive is a thixotropic agent designed to transform SRTM60089 2K RTV Platinum Cure Silicone Rubber into a brushable, creamy paste. This makes it ideal for filling tight details, building up corners, and preventing sagging when brushing onto vertical or complex surfaces.
Easy to Use:
- Dispense the desired amount of mixed SRTM60089 RTV Silicone through the Infuser SS sprayer into a mixing cup.
- Add approximately 20 drops of Thickening Additive per pound (454 g) of pre-mixed silicone rubber.
- Mix thoroughly with a stir stick — the silicone rubber will instantly change from a free-flowing liquid to a smooth, paste-like consistency.
With this simple addition, your silicone becomes more versatile, enabling precise detailing and controlled application for reusable membrane construction.
