JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
L&L Products has introduced A-K540 to meet the strong demand from customers for a fast-curing structural adhesive capable of providing direct robust adhesion to low surface energy plastics.
Part of its L&L Bond A-K Series of room temperature cure structural adhesives, A-K540 is considered to be unique in that it is able to combine direct adhesion - without primer, plasma, corona or flame treatments - to substrates such as polypropylene (PP) and polyethylene (PE) with very fast cure speeds at room temperature. A-K540 is also capable of bonding a multitude of other substrates, thereby enabling polyolefin plastics to be combined with metals, composites and wood.It also offers high tensile strength and excellent impact resistance A-K540 is expected to be of particular interest to the automotive industry in general and specifically commercial vehicle manufacturers and coach builders. Typical applications in this area include structural bonding of PP interior trim (including dashboards, door panels and centre consoles), structural assembly of talc filled PP / TPO (thermoplastic polyolefin) bumper modules, and structural modules incorporating glass mat thermoplastics (GMT) or long glass fibre polypropylene (LGFPP).A-K540 is easy to use and is available in 50 ml or 400 ml cartridges ( 0.1 and 0.85 US pints), 19 litre pails (5 US gal.) or 190 litre drums (50 US gal.).More information:www.llproducts.com
