Bus body to chassis - Plexus Bonds ‘Alero’
UK based Optare manufactures the low floor minibus the ‘Alero’ which is used to allow easy wheelchair access, use on rural routes and in airports The Alero comprises of a one piece colour impregnated composite body into which a stainless steel roll frame is incorporated during the moulding process.
Optare required a strong but flexible adhesive to bond the composite body to the stainless steel frame. Due to the size of the components, they needed an adhesive that had an open lead time of at least 30 minutes but a cure time of 90 minutes.
Plexus MA556 provided the solution to meet with all their criteria and combined no preparation was requirements on the GRP meant that Optare could reduce their labour costs compared with Polyurethane adhesives.
