Since silicone fluid, hydrocarbon-based oils, and UV absorbers tend to separate, are there any recommended products?

Product Category Silicone FluidsMethylphenyl Silicones

As the molecular weight of silicone fluid increases, its solubility decreases. Therefore, we recommend considering low-molecular-weight silicone fluid.
The low-molecular-weight phenyl-modified silicone fluid 「KF-56A」 exhibits good solubility with hydrocarbon-based oils and UV absorbers, making it suitable for use as a compatibilizer.
Additionally, the volatile silicone fluid 「KF-4422」, which replaces some methyl groups in dimethyl silicone with ethyl groups, also demonstrates high compatibility with various oils.
