How are silicones used?
Silicones are highly valued materials because they have a combination of physical properties not found in other polymers. They have outstanding heat stability and can be used in applications where organic materials would melt or decompose. Many silicones seem to be impervious to the effects of aging, weather, sunlight, moisture, heat, cold, and some chemical assaults. Some silicones are used to stick, bond, or couple things together ¨C a glue, if you please.
However, unique surface properties make silicones really different from other materials. The low surface tension of silicone fluids make them ideal for applications such as:
Paper release agents
Fiber lubricants
Textile hand modifiers
Mold release agents
Antifouling materials
Water repellents
In fact, silicones have been used as foam-control agents, anticaking aids, corrosion inhibitors, emulsifiers, lubricants, conditioners, and gloss enhancers ¨C all because of their unique surface properties.
Amino
- Adhesion promoter, coupling agent, and resin additive
- Improves chemical bonding of resins to inorganic fillers and reinforcing materials
- Used for epoxies, phenolics, melamines, nylons, PVC, acrylics, poly(olefins), poly(urethanes), and nitrile rubbers
- Surface pretreatment of fillers and reinforcers
Vinyl
- Used for free-radical, cross-linked polyester, rubber, poly(olefins), styrenics, and acrylics
- Used to couple fiberglass to resins
- Used to copolymerize with ethylene
- Used to graft to poly(ethylene) for moisture cure
Epoxy
- Adhesion promoter for epoxies, urethanes, and acrylics
- Surface treatment for fillers and reinforcers
Methacryl
- Adhesion promoter and coupling agent
- Used for free-radical, cross-linked polyester, rubber, poly(olefins), styrenics, and acrylics
- Used to couple fillers or fiberglass to resins
- Moisture cross-linking of acrylics
Sulfur
- Used as coupling agent for inorganic fillers in sulfur-vulcanized rubber mixtures
Alkyl
- Hydrophobic surface treatment of fillers and inorganic surfaces
- Silicone synthesis
Phenyl
- Synthesis of silanes and siloxanes
- Hydrophobic surface treatment
- Hydrophobic additive to other silane coupling agents
- Thermal stability additive to other silanes.
