MQ silicone resin is composed of monofunctional siloxane units (M) and tetrafunctional siloxane units (Q), with a molecular weight typically ranging from 1,000 to 8,000. The M/Q ratio and molecular structure determine the resin‘s properties and application scope. IOTA-7080 offers precisely controlled M/Q ratios, ensuring consistent quality and reliable performance.
