“In PV panels and wind turbines, the power densities of inverters are increasing,” said the company. “With higher junction temperature associated with higher voltages and greater electrical loads of the 7th generation IGBT technology, a silicone gel needs to have strong dielectric properties and enhanced thermal resistance.”
EG-4175 is the material, which is mixed before use from equal amounts of two precursors with matching viscosity.
It self-primes for adhesion without a separate primer, and cures at room temperature – although heat may be used to accelerate curing.
In use, “the material absorbs vibrations and has self-healing properties that repair small cracks without external intervention”, claimed Dow.
