L&L Products, a global applied engineering & materials science company, has invented a new innovative material as part of the L&L Bond A-K series of room temperature cure structural adhesives, to meet the customer demand for a fast-curing structural adhesive, capable of providing robust direct adhesion to low surface energy plastics.

Titled, L&L Bond A-K540, the new structural adhesive is unique as it combines direct adhesion, without primers or plasma, corona, flame treatment, to low energy substrates such as polypropylene and polyethylene thermoplastics with very fast cure speeds at room temperature.

A-K540 is also capable of bonding a multitude of other substrates, enabling combinations of polyolefin plastics with metal and composite substrates.

L&L Bond A-K540 is specially formulated for structural bonding of PP interior trim, including dashboards, door panels and center consoles. Other key applications include structural assembly of talc filled PP / TPO bumper modules, and structural modules incorporating GMT or long glass fibre filled PP (LGFPP).

With high tensile strength and impact resistance, A-K540 possesses long term durability for applications in challenging operating conditions.

L&L Products is a technology driven, business-to-business company that has unique expertise in static sealing, acoustics, vibration reduction, structural reinforcements and composite components for automotive, aerospace, commercial vehicle, and other industrial applications. (GK)
