TIG680-28AB — Product overview
TIG® 680-28AB Series is a two-component high thermal conductivity silicone sealant with room temperature curing, long working time, and flame retardant properties. This product is particularly suitable for sealing capacitors and small electronic devices. Its excellent flexibility properties enable it to provide excellent cushioning protection for coating materials. The low viscosity characteristic enables the thermal conductive sealant to cover the surface more comprehensively, greatly improving the heat transfer efficiency of the heating element or the entire printed circuit board to the metal shell or heat dissipation plate, thereby improving the performance and service life of electronic components.
