RadiBond™ – Welding Primer for Thermoplastics

RadiBond™ Metal-Plastic Welding Primer is a high performing surface primer, applicable for any type of inorganic material (and certain plastics), used when you want to assemble a plastic part onto a non-binding surface through a welding technique. Any type of welding technique that melt the joining interphase can generally be used (dependent on the plastic chemistry), including heat, ultrasonic, solvent and heat pressing. The Welding Primer layer is stable after application and can be stored for several months before the plastic part is welded on.

Welding of High-End Engineering Thermoplastic Composites

With RadiBond Welding primer, you can actually weld plastic materials directly to metals and get a very high strength of the bonding. Stronger than you would be able to achieve with some of the best performing structural adhesives on the market.

In lap-shear tests, we obtain up to 40 MPa in strength for some of the most difficult to bond polymer materials like PEEK and PPS carbon fiber composites.

Welding of thermoplastic composite materials onto metal allows you completely new assembly strategies and design opportunities in the design of hybrid components of metals and composites. You can use any suitable welding technique, that is able to melt the interface of your thermoplastic material. It ranges from ultrasonic welding, laser welding and induction heating of the metal part.

Welding of metals to thermoplastics

We have shown that we can weld a broad range of metals to thermoplastic polymers. With our unique polymer brush-based primer systems, you can weld aluminum to thermoplastics, stainless steel to thermoplastic composites, titanium to composite materials, etc. Contact us to learn if we have any experience with the substrate you have in mind for your application.
