Customized for refractory mica insulation, IOTA 3922A features superior heat resistance, flexibility, electrical insulation and moisture weatherability. It emits little non-toxic smoke and produces no carbon residue under flame, retaining stable insulation during fire to guarantee power supply of fire-resistant cables. The film delivers cohesive, anchoring and adhesive force to firmly bond mica paper and fiberglass cloth without cracking or delamination upon bending, perfect for mica tapes of motors, wind power and fire-proof wires. Stable formula with controllable solid content forms uniform coating without particles; cured flexible substrate enables smooth winding. Clear storage & transport rules with long shelf life suit high-end fire-resistant cables and high-voltage motor insulation. Superior to foreign silicone resins in heat resistance, adhesion and humidity tolerance, it serves as a cost-effective domestic alternative for electrical insulation materials.
