Abstract

Disclosed are one-component compositions that include: (1) an isocyanate-functional urethane acrylate and (2) a polyisocyanate containing allophanate and/or uretdione groups, wherein the one-component composition has a viscosity of less than or equal to about 800 mPa·s and an isocyanate content of greater than about 5% by weight, based on the weight of the one-component composition. Also disclosed are circuit boards and electronic components that are coated with such compositions.
