Abstract: This patent describes formaldehyde free or formaldehyde reduced binders useful, for example, in a fiber based composite material such as glass or other mineral fiber insulation, non-woven fabric or wood-based board. In one example, melamine is used as an acidic solution or a salt. The salt or solution is used to create an aqueous binder with other components such as a polyol and a crosslinker. A preferred polyol is a nanoparticle comprising high molecular weight starch. In other examples, binders include mixtures of a polyol with urea and a crosslinker. In other examples, a multi-component nanoparticle is made by reacting a polyol such as starch in an extruder with an insolubilizer such as melamine or urea. The resulting particles are mixed with water, optionally with other components such as an additional crosslinker, to create an aqueous binder.

Abstract: Disclosed are a coupling agent for a rubber composition and a rubber composition for a tire containing the same. The rubber composition according to the present disclosure contains a coupling agent that may induce interactions between a rubber as a raw material and carbon black, thereby improving dispersibility of the carbon black in the rubber composition. Thus, a tire with low rolling-resistance and excellent wear resistance may be realized.
