Dow has introduced three new silicone technologies for electric and hybrid-electric vehicle electronics applications. The company says these new products – Dowsil TC-2035 CV Adhesive, Dowsil TC-4551 CV Gap Filler and Dowsil TC-4060 GB250 Thermal Gel – are manufactured for reliable performance, high thermal conductivity, controlled volatility for very efficient heat dissipation and easy processing for enhanced productivity.
Dow says the Dowsil TC-2035 CV Adhesive delivers high thermal conductivity, a fast cure and good room-temperature shelf-life stability for the assembly of automotive electronics, including advanced driver assistance systems (ADAS) units and electronic control units (ECUs). Dowsil TC-4551 CV Gap Filler also provides high thermal conductivity and reliable performance in automotive power electronics, ECUs and ADAS, the company adds.
The new Dowsil TC-2035 CV Adhesive and Dowsil TC-4551 CV Gap Filler feature controlled volatility, Dow says, which supports sustainability and regulatory compliance and helps to avoid electrical contact failure that can occur due to the evaporation of volatiles.
The third new product, Dowsil TC-4060 GB250 Thermal Gel, provides the highest thermal conductivity of the new grades, at 6 W/m.K, Dow says. The company says the heat dissipation capability of this material, combined with its dispensing properties, makes it a great candidate for applications such as converters, inverters and onboard chargers for battery packs. This soft thermal gel also supplies stress relief and shock damping and performs reliably under high-power and high-temperature conditions, Dow says.
