Colorants for Liquid Silicone Rubber

Colorants for liquid silicone rubber can be used in a variety of applications, including healthcare

These silicone paste colorants can be used in one-component and two-component Room Temperature Vulcanization (RTV) systems and two-part Liquid Injection Molding (LIM) systems. Formulations can be developed for indoor or outdoor light-fastness, chemical resistance, heat stability, ease of dispersion and heavy-metal replacement.

They provide excellent dispersion, consistent color, and a suitable viscosity for metering systems. Select one of our standard colors, or speak to our team of formulation experts to develop a custom color for your product.
