Soldermask protected from Electromigration

Engineer asked Nov 09,2019

Hello, i need to protect my automotive PCB, with LED, from electromigration, to avoid creepage current. The customer req is 1,1 mm beetween power supply track, i instead have no more 0,25 mm gap. so he asked to me to have a proper coating to avoid electromigration issue. Do it exist a simple soldermask ink that has also coating properties, and can protect from electromigration? i need to avoid the standard conformal coating for cost increase.
