Information on Dissolving Coal Tar Solution

Based on our product database search, we could not find specific surfactants recommended for dissolving Coal Tar Solution directly.

Coal Tar Solution is a complex substance with multiple components. Dissolving it in certain solvents can be challenging and may lead to separation or precipitation, as you experienced when trying to dissolve it in VG (Vegetable Glycerin). Warming the VG might temporarily improve dispersion but does not result in complete dissolution. The precipitate issue indicates that the Coal Tar Solution is not fully dissolved in VG but is in the form of an unstable dispersion.

Although we did not find surfactants that directly aid dissolution, there are certain types of additives that can help improve the dispersion of undissolved particles and prevent settling. These are known as dispersing agents or anti-settling additives.

From the search results, we found products that may possess these properties:

• BYK 410 (Anti-Settling Additive): An additive that helps prevent the settling of particles in a formulation.
• BYK 185 (Dispersing for solvent-borne additive): A dispersing agent for use in solvent-borne systems.

These additives do not cause Coal Tar Solution to dissolve in VG but help the undissolved portion disperse better within the VG, reducing issues of separation or hard settling. However, their effectiveness will depend on the specific characteristics of the Coal Tar Solution used and its concentration in the formulation.

If complete dissolution of Coal Tar Solution is required, you may need to consider using other solvents that are more suitable for its properties than VG, or you may need to use other formulation techniques that help the substance remain stable in the best possible dispersed form.
