 * Bonds without
pretreating
* Solvent-free acrylic
Easy solutions for hard-to-bond plastics. 
Bonding low surface energy (LSE) plastics such as polypropylene or other thermoplastic
olefins with conventional tapes and adhesives typically requires the surfaces to be
primed, flame treated or corona treated. These new adhesives and tapes can bond low
surface energy plastics without pretreatment. Scotch-Weld Structural Plastic Adhesive
DP-8005 uses a two-part solvent-free acrylic adhesive technology that does not require
pretreating. The structural bond is often greater than the strength of the substrates
joined. The adhesive cures at room temperature, saving cost, time, oven-curing space, UV
lamps and heaters. Scotch-Weld Adhesive DP-8005 also resists many chemicals, water,
humidity and corrosion. 3M Corp, South St. Paul, MN. Go direct to spec
