Q-Prime® 

Our proprietary Q-Prime® thermal adhesive enhances flexible circuit thermal management to help your LED designs take shape.

Let LED designs take shape. 

Designed specifically for high-current, thermal control applications requiring heat dissipation, Q-Prime® technology has been relied on throughout the automotive industry for over 30 years. Designed with heat conductive adhesive (Novaclad® / Novaclad® HDI), Q-Prime® enables attached components to run at cooler temperatures than traditional flex constructions.

Q-Prime® flexible circuit technology is well suited for automotive applications, including headlamps, fog lamps, DRL, indicators, and HUDs. And with its ability to reduce cost, solve heat concerns, and deliver long-term reliability, Q-Prime® is redefining what’s possible for a range of LED applications across several industries. 

Q-Prime® enables more flexibility for your automotive LED application designs. 
Create customized looks for outdoor applications.  
Ambient lighting for vehicle interiors.
