The present invention relates to a very high solid content contact adhesive (VHS) which has a higher solid content than previously thought attainable in the prior art without increasing the viscosity beyond operable levels. Additionally, the present invention provides a VHS application device which allows substantially more uniform application of the VHS than was previously attainable.
