L&L A-K540 from Intertronics is an innovative structural adhesive that combines direct adhesion – without primers or plasma, corona, or flame treatment – to low energy substrates such as polypropylene and polyethylene thermoplastics, with very fast cure speeds at room temperature. It is also capable of bonding a multitude of other substrates, enabling combinations of polyolefin plastics with metal and composite substrates.
The product is a two-component methacrylate based structural adhesive which has a fixture time of just 45-60 minutes. It has high tensile strength and impact resistance with robust long term durability for applications in challenging operating conditions. It is resistant to weathering, such as salt spray and QUV radiation; properties developed in response to its original purpose in vehicle assembly applications where it has proved to be extremely successful worldwide, offering exemplary performance as a high strength, light-weight structural adhesive for major motor manufacturers.
