Abstract: A method for producing a fast drying high solids adhesive wherein a water based polymer emulsion (latex) is modified with unemulsified elasticizing oils and reinforcing-tackifying resins to produce a stable emulsion of polymer, oil and resin without the use of additional emulsifiers or volatile organic solvents. When packaged in pressurizable canisters along with a suitable propellant, the adhesive may be sprayed through a suitable nozzle and deposited in a thin layer to form an adhesive film which has excellent bonding characteristics for many laminates such as fabric or textiles, wood, plastics, metals and rubber, and for adhering flooring materials such as carpet, linoleum, tiles and artificial grass to a variety of substrates.

Abstract: A method of producing a high solids adhesive is provided wherein a buffered latex emulsion, such as, for example, styrene butadiene latex emulsion buffered to a pH of 11.0 using caustic agents, is combined with a non-emulsified mixture of dissolving process oils and tackifying resins and mineral fillers. The resultant adhesive has a solids content greater than previously achieved in the industry and has exceptional adhesive characteristics such as increased bond strength, improved durability, better aging, faster drying, improved water resistance and improved freeze resistance. High solids content is achieved by taking advantage of the excess emulsifiers in the latex emulsion and adding the remaining constituent components directly to the stabilized latex emulsion.
