Abstract:
1. A method for forming a hybrid polymer composition, comprising the steps of: preparing a first part that includes a phenol-aldehyde pre-polymer and a polyurethane catalyst; preparing a second part that includes a polyisocyanate pre-polymer and a phenol-aldehyde cure accelerator; combining the first part and the second part to form a hybrid pre-polymer composition; and thereafter applying the hybrid pre-polymer composition to a substrate material that includes cellulose, lignocellulose, and combinations thereof, inducing reaction of the hybrid pre-polymer composition to form the hybrid polymer composition, including curing the applied hybrid pre-polymer composition to form the hybrid polymer composition, wherein said hybrid pre-polymer composition has a gel time, as measured from the mixture of the pre-polymer composition, of less than about 9000 seconds at ambient temperature.
