Kootai 9239 is a single-component, room-temperature vulcanizing (RTV) silicone adhesive designed for high-performance bonding, thermal conductivity, and long-term durability. It cures through ambient moisture without the need for mixing or external heating, forming a tough yet elastic silicone layer ideal for electronic component bonding, gap filling, and PCBA protection. With a thermal conductivity of 0.5 W/m·K, dielectric strength of 14 kV/mm, and UL94-certified flame retardance, it ensures reliable heat dissipation and electrical insulation in demanding applications.
This adhesive adheres well to metals, plastics, ceramics, glass, and printed circuit boards, making it versatile across LED modules, power electronics, and industrial assemblies. Its non-corrosive, halogen-free, and sulfur-free formulation is safe for sensitive components and meets global standards, including RoHS, REACH, and UL certifications. Kootai 9239 offers a multifunctional solution by acting as an adhesive, thermal interface material, insulator, and sealantmaking it a preferred choice for modern electronics manufacturing and thermal management.
