Stan-Tone™ pigment dispersions find broad application in thermoset castable polyurethane systems. Selection of the best pigment dispersion depends on a number of factors, including:
- Specific urethane system
- Fabrication/processing methods
- End-use requirements
- Economy
Polyester-Based Systems
Stan-Tone PEP colors (diethylene glycol adipate) are reactive and compatible with polyester systems, reacting to become part of the final cured product. In addition to their use in polyester polyurethanes, Stan-Tone PEP colorants are suitable for use in a variety of thermoset polyester systems. Applications include pultrusion and SCM compounds, cast polymer countertops, glass-reinforced composites and coated fabrics. PolyOne offers a custom PEP vehicle system especially suitable for gelcote applications.
Special Dispersions
Stan-Tone dispersions are available in a variety of other vehicles, such as Benzoflex 9-88 (dipropylene glycol dibenzoate). Benzoflex has the advantage of compatibility in both polyether and polyester systems. Customer-specified carrier systems and custom color-match pigment blends are available.
