Abstract:
A method of forming a binder composition includes providing a urea-formaldehyde resin and combining one or more starch compounds with the urea-formaldehyde resin to form a starch modified urea-formaldehyde resin. The one or more starch compounds may be combined with the urea-formaldehyde resin so that the starch modified urea-formaldehyde resin includes about 1 wt. % to about 10 wt. % of the one or more starch compounds.
