Abstract

A vehicle interior component fabricated using a hot melt adhesive having two base polymers with different melting points, a higher melting point and a lower melting point, for bonding the surfaces of at least two layers of the vehicle interior component. The hot melt adhesive is applied to one of the layers in an activated state at a temperature equal to or greater than the higher melting point and closely bonds with the layer when the adhesive cools to a temperature below the higher melting point. The bond between the two layers is effected at a lower temperature corresponding to the lower melting point to enable removal of the component layers from a mold while still in a warm state.
