Scott Bader, a UK-based chemical company, has developed two new Crestabond grades of methacrylate primer-less structural adhesives, Crestabond M7-05 Black and M7-15 Black.

The new adhesives have been specifically developed by Scott Bader in response to customer demand, particularly from fabricators bonding pigmented ABS and carbon fibre (CF) composite components.

With the significant growth in applications now specifying CF to achieve a lighter weight, the need for a black pigmented adhesive system has significantly increased for the latest designs of finished composite parts now being structurally bonded in applications for motorsports, high performance and luxury cars, electric vehicles, racing yachts, and sports equipment, where aesthetics and finish quality are very important.

The two new black coloured M7 grades added to the 1:1 ratio Crestabond range now offer manufacturers a colour choice of either off-white or black, which can be a significant application benefit to meet any aesthetic requirements in addition to bond performance. Both new black coloured grades are variants of the existing Crestabond M7 off-white grades in the range. They exhibit the same attributes, handling and performance properties including: excellent fatigue and impact resistance; good gap filling capabilities up to 5mm; with minimal surface preparation required prior to bonding, according to a company statement.

As with the rest of the M7 range, both M7-05 Black and M7-15 Black are suitable for bonding a wide range of popular engineering material substrates such as: FRP, stainless steel, aluminium, cold rolled and galvanised metals, abs, acrylic and polycarbonate. (GK)
