Master Bond (Hackensack, NJ) MB514 polypropylene adhesive etches away at the bonding challenges presented by non-polar and low energy polyolefin surfaces. Typically, a pretreatment stage, which may include flame treatment, etching or roughening, is required before being able to bond polyolefin substrates. Specially formulated to eliminate this time consuming stage, the MB514 polyolefin based hot melt is particularly suited for use on untreated surfaces of polyethylene, polypropylene and combinations of these substrates. Additional features include:
Melting these compositions and then applying the molten hot melt to the surfaces to be bonded are the only required processing steps.
An excellent bond performance is retained over a temperature range from -29° to 88°C.
A VOC free structure that is 100 percent solids and contains no solvents.
Bond strengths that develop rapidly with no need for clamps or post cure during assembly.
Rapid cure speed, which makes it ideal for high-speed assembly operations as the bonds are formed immediately upon cooling.
