Commonly added silicone thinner ratios
Reference experience value: For some common liquid silicone and commonly used silicone thinner combinations, there are some approximate empirical addition ratios for reference. For example, for some common addition-type liquid silicone, when using silicone rubber special silicone thinners, the addition ratio may be around 5% - 20% of the total volume of silicone. But this is only a preliminary reference, and the actual ratio may vary depending on the specific formula of the silicone, processing technology and other factors.
Conduct a small test to determine: It is usually necessary to conduct a small-scale test to accurately determine the addition ratio. You can first take a small amount of liquid silicone (such as 100 grams or 200 grams), add silicone thinners in different proportions, such as 5%, 10%, 15%, 20%, etc. (based on the volume or weight of silicone), and then observe the fluidity and viscosity changes of the silicone after adding the silicone thinner, as well as the subsequent performance of simulated processing operations (such as simulated pouring into a small mold, or simulated coating on a small piece of material, etc.). Based on these test results, select the addition ratio that best meets the processing requirements and has the least impact on the performance of the silicone.
