This company announces the development of a pressure sensitive adhesive that exhibits excellent adhesion to untreated polypropylene and polyethylene. Scibond 100 is a 60%-solids, water-based emulsion polymer that adheres to the difficult-to-bond polyolefin surfaces without the need for pre-treating or the addition of wetting aids. The adhesive forms a smooth, even coating on the polymer surface, and does not exhibit the pullback seen with standard water-based adhesives. Circle No. 120
