Q&A About Polyurethanes

What types of surface preparation are necessary to obtain strong and durable bonds?

Having a clean surface is a key requirement to obtain a strong and reliable bond.

September 1, 2016

Companies using adhesives are expected to be able to consistently produce an assembly―whether in the flexible packaging, furniture, automotive or construction industry―without differences in the quality of the product manufactured. This is the case for both high-performance structural bonds and applications with lower performance requirements.
