Applications
IOTA 606 is an essential precursor in silicone chemistry, widely used to manufacture:
Functional End-Capped Siloxanes: Serves as a chain blocker or end-capper in the production of silanol-terminated and vinyl-terminated polysiloxanes.
Silicone Surfactants: A key raw material for creating high-performance surfactants used in polyurethane foam production.
Liquid Silicone Rubbers (LSR): Used in the synthesis of cross-linkers and base polymers for LSR applications.
Modified Silicone Oils: Enables the creation of silicone oils with organic modifications for specialized properties.
Plastics & Resins: Acts as an intermediate for additives that improve processing or surface characteristics.
Handling & Safety
Handle with care. IOTA 606 is a highly flammable liquid and vapor.
It should be stored in a cool, well-ventilated area away from ignition sources.
Decomposes upon contact with water, releasing hydrogen gas.
Personal protective equipment (PPE), including safety glasses and gloves, is recommended during handling.
