Coupling agent produced from naturally fermented and sustainable additives
A coupling agent composition is provided and includes a plurality of non-toxic components and a thickening agent. The plurality of non-toxic components is derived from one or more natural resource materials and is an amount equal to or greater than 97 weight percent (wt %) of the composition. The thickening agent is provided in an amount of 0.05-5.00 wt % of the composition. The balance of the composition is incidental impurities.
