Patent ID: 8729157

Claim:
A high solids oil-in-water emulsion adhesive wherein the solids content of the adhesive is greater than 70% made by a process comprising of: preparing a molten uniform oil phase formulation, comprising of a hydrophobic material and surfactants, slowly adding an oil-in-water water-based formulation to the said molten oil phase such that the added said oil-in-water water-based formulation forms an oil-in-water-in-oil emulsion while maintaining such a suspension by agitation, continue adding increasing quantity of the said oil-in-water water-based formulation to the said formed oil-in-water-in-oil suspension until the oil-in-water-in-oil suspension inverts to an oil-in-water suspension with both types of oil phase particles co-existing in the continuous water phase of the suspension, optionally adding additional amounts of the said oil-in-water water-based formulation to bring the % solids of the formed oil-in-water suspension to the solids level desired.
