Flexible adhesives for plastics (ABS)



ABS is a high-performance plastic commonly used for automotive bodyparts, dashboards and decorative interior panelling. The demand to seal and bond ABS components is ever increasing as the automotive industry wish to take full advantage of the versatile plastic, combined with the benefits adhesives offer - Fast operation times, easy application procedures, maintain ABS strength & integrity by avoiding destructive riveting, professional finishing, and reduced weight of the vehicle meaning greater fuel efficiency.
Unfortunately for many adhesives bonding ABS is a major problem, here at Forgeway® we love a challenge and see problems as opportunities. To overcoming such formidable challenges, we seek to fully understand the problem. ABS bonding is a layered problem which needs to be unravelled to find the solution.
ABS is ABS right? Wrong! Our knowledge of ABS means we understand that any two given ABS’s are rarely the same. ABS is available in various compositions depending on the desired nature of the finished product, and these compositions have various surface energies. The surface energy of ABS determines the ease at which the adhesive can interact with the bonding area. The lower the surface energy the harder it is to bond. ABS can have low to very low surface energy depending its composition.
Some ABS adhesives overcome the low surface energy by essentially melting its surface, such solvent based adhesives describe this as a chemical weld. Whilst the principle is good the practice is far from it. This bond formation is closer to chemical attack which breaks down the ABS leaving it vulnerable to environmental stress cracking – early life failure.
With the problems facing vehicle manufacturers in full view, Forgeway® adhesives are developed to meet the challenges head on, and to pass the most stringent of examinations before being taken to the market -
Glues with high IQ’s is more than just a moto.


Formoa® 206i is the lean fighting fit 6-pack of ABS adhesives. It can also
be used in conjunction with Formoa® Surface Activator + for the lowest surface energy ABS’s, providing vehicle manufacturers with a nondestructive ABS bonding solution ensuring high quality & maximum performance over the lifetime of the vehicle. Formoa® 206i will also give excellent adhesion to polycarbonate, ASA, Metals, GRP, and many other substrates.
In 1963, Lego changed the plastic their bricks were made from to ABS. The only downside was that, unlike cellulose acetate, ABS is opaque, so transparent Lego parts can't be made from it. In these cases, a polycarbonate plastic is now used instead.

Adhesives Chapters 1,2 & 4 for a greater look at bonding.
