The present invention provides bonding systems comprising a formaldehyde-based (urea-/melamine-/phenol-/resorcinol-formaldehyde or other combination) and/or a polymeric isocyanate resin system composition for bonding ligno-cellulosic materials to form panels and/or shaped products, which contain a resin hardener, also referred to as resin catalyst, characterised in that the hardener is activated by heat.
