Pigment Zhermack for Coloring RTV Silicone - 1 kg

Pigment concentrate for mass coloring of RTV silicone

Zhermack silicone pigment is an auxiliary product used for the mass coloring of RTV silicone. The pigment is embedded in material before use, allowing a uniform colour to be obtained in the mass of Silicone.

The product is available in several colors and can be used when the standard color of the silicone is not suitable for the application or when visual differentiation of the molds, layers or marks made of silicone is required.

Available colors

Zhermack technical documentation mentions the following variants:

• Black / Black - Color Index PBK 7;
• White / White - Color Index PW 6;
• Red / Red - Color Index PR 254;
• Blue / Blue - Color Index PB 15: 1;
• Green / Green - Color Index PG 7;
• Yellow / Yellow - Color Index PY 138;
• Red-brown / Brownish Red - Color Index PR 101;
• Orange / Orange.

Recommended applications

Pigment is used for mass coloring of the RTV silicone. In practice, pigmentation can be useful for:

• obtaining a different color from the standard color of Silicone;
• Visual differentiation of molds or silicone markers;
• Getting a visual contrast the model or material used in the process;
• easier identification of some moulds or components in a workshop or production process;
• applications where the final colour of the silicone has a functional or aesthetic role.

Use with addition RTV2 silicone

For addition RTV2 silicone, pigment should be distributed and uniformly homogenised in the mass of the components prior to the preparation of the working sled.

In Best TOOLS practice, when it is necessary to obtain the same shades during a project, pigment is included separately in the amount of BASE And in quantity CATALYST necessary for the project. Each component homogenizes very well, after which the already pigmented materials weigh the successive working sarges.

Important: pigmentation does not alter the BASE ratio: CATALYST specified for RTV2 silicone. The mixing ratio indicated for the silicone used must continue to be observed when preparing each batch.

Silicone use RTV condensation

For condensing RTV systems, Best TOOLS pigment can be homogenized in the basic component prior to adding the tentor.

After obtaining a uniform colour in the base mass, prepare the working sands and add the intensifier respecting the dosage and instructions specific to the silicone condensation used.

Note: These incorporation procedures come from Best TOOLS practice experience. The supplied pigment technique does not describe a separate dosing procedure for addition and condensation systems.

Information about pigments used

For black, white, red, blue, green, yellow and red-brown variants, Zhermack documentation provides information on Color Index, pigment density and resistance to light.

For the orange variant, the documentation indicates a carrier based on silicone polymer with methyl termination and specifies that the product is Lead and cadmium-free according to EEC Directive 2002 / 72.

Best TOOLS Recommendations

In silicone pigmentation, the objective is not to use as much pigment as possible, but to obtain color and intensity required with a uniform distribution.

First add a small amount, mix very well and evaluate the result. If the hue needs to be intensified, proceed progressively. This method provides better control than adding a large amount of pigment from the beginning.

If the project requires multiple injections or successive applications and it is important that they all have the same shadeWe recommend the pigmentation and homogenization from the beginning of the total amount of BASE and, separately, the total quantity of CATALYST required for the project.

The working sarges are subsequently weighed from already pigmented components, respecting the mixing ratio of the silicone. This method makes it possible to obtain a much more uniform colour between the successive sarges and avoids the need for repeated dosing of very small amounts of pigment.

For very large projects, where the subsequent reproduction of a color formula is necessary, weighing and documenting the amounts of pigment used can help to repeat as closely as possible in the following lots.

Useful complementary products:

• addition of silicone RTV - for the production of pigmented moulds and markers;
• Silicone RTV condensation - for applications in which this system is used;
• precision scale - to prepare components and, where possible, control the amount of pigment;
• mixed containers - for the preparation of the material,
• Mixture spatula - to homogenise pigment in silicone.

Common questions about silicone pigments

Conclusion

Zhermack pigments for RTV silicone are auxiliary products designed for uniform mass coloring of silicone. The color range is available to adapt the visual appearance and contrast of the material to the desired application.

Since the available technical chart does not establish a universal percentage of dosing, pigmentation should be achieved by progressive addition and careful homogenisation. For projects processed in several sands, the prior pigmentation of the total quantities of components allows maintaining a uniform colour during the work, without the need for repeated dosing of the pigment in each sled.
