Does silicone caulk dissolve in solvent?
A Silicone Solvent Actually Digests Silicone. When a solvent dissolves a solute, it breaks the solute into atoms or molecules that can disperse in the solvent. The cross-linked bonds of silicone caulk are too strong to dissolve in this way, but some chemicals can cleave the siloxane bonds and break the long polymer chains into smaller molecules.
How to remove silicon from silicone?
I do not know of any published methods, but I have taken the process some ways. First heat the silicon in air to around 600 C or greater. This will convert the silicone to silica (SiO2). Then load your blast furnace with the highest quality charcoal and add your silica, then fire it up. The charcoal will make CO (g) that will react a high temperatures to make CO2 and Si. The result will be moderately pure silicon that can be clean-up in your zone refining

- Silicone adhesives are becoming more widely used in microelectronic hybrid assemblies due to their inherently low elastic modulus, which relieves stress between substrates with different coefficients of thermal expansion (CTE) during thermal cycling. They can be formulated with varied mechanical and chemical properties that influence the choice of chemicals and processe…
Experimental Evaluation
- Individual combinations of silicones, substrates, and cleaning solutions were evaluated, and a removal-rate rating system was developed to be used as a reference guide and assist in selection of the optimal silicone-removal solutions based on assembly configuration, material substrates, and silicone. The substrates and silicones chosen are commonly used in microelectronic assem…
Results and Discussion
- The results of the study demonstrated removal effectiveness of solvent or silicone emulsifier (Table 1), effects of silicone type on removal rate, and change in substrates. As hypothesized, the solvents did not dissolve or break down the siloxane bonds. IPA did not produce delamination between the silicone and substrate within 24 hours in these test conditions, where as xylene sho…
Conclusion
- Solvents were not as efficient as silicone digesters in removing cured silicone. Each silicone digesting solution dissolved the silicone within 24 hours, with the exception of the DA. Commercially available silicone emulsifiers evaluated may not have dissolved the cured silicone as quickly as the 1% TBAF solution, but they demonstrated a reasonable...
