Disclosed is a composition comprising an electrophile, a nucleophile, and a thermally conductive filler package. The filler package may comprise thermally conductive, electrically insulative filler particles that may have a thermal conductivity of at least 5 W/m·K (measured according to ASTM D7984) and a volume resistivity of at least 10 Ω·m (measured according to ASTM D257, C611, or B193) and that may be present in an amount of at least 90% by volume based on total volume of the filler package. The thermally conductive filler package may be present in an amount of at least 10% by volume percent based on total volume of the composition. The present invention also is directed to a method for treating a substrate and to substrates comprising a layer formed from a compositions disclosed herein.

Compositions containing thermally conductive fillers

Disclosed herein is a composition comprising: an epoxy-containing component, elastomeric particles in an amount of greater than 11% by weight to 25% by weight based on total weight of the composition; and a curing component activatable by an external energy source, the curing component comprising at least one guanidine having a D90 particle size of 25 μm measured by dynamic light scattering. Also disclosed is the composition in an at least partially cured state. Also disclosed is a method for treating a substrate comprising applying the composition to a surface of a substrate; and applying an external energy source to cure the composition. Also disclosed are substrates comprising the composition. Also disclosed are substrates formed by the method of the present invention.
