Stan-Tone™ SMB colors use polydimethyl silicone elastomer gum binders in cuttable masterbatches (mass or various size slabs). Applications include:
- Mechanical seals
- Key pads
- Gaskets
- Wire and cable
- Air bags
Silicone elastomers are comprised of thermoset gum rubber, one- and two-component RTV systems and two-part LIM systems. Selection of a colorant must be made to meet the individual requirements of a specific application.
Key Characteristics
Thermoset Gum Rubber
Typically based on linear fluids or gums with fillers and cured with organic peroxides, thermoset gums are processed on conventional rubber processing equipment (two-roll mill, internal mixer, extruder). They are used for a variety of applications, typically using conventional fabrication methods, such as compression, injection, extrusion and transfer molding. The cure time and temperature, post-cure and end-use requirements are all factors in selection of pigments.
Typically the colorant is in masterbatch, SMB, form for ease of handling, especially for two-roll, open-mill mixing. There are also colorants available in the form of high-viscosity pastes for use in various thermoset applications.
Stan-Tone SMB colors are based on a silicone gum binder system. A wide range of high-temperature, organic and inorganic pigments are available.
