The RadiBond™ Metal-Polymer Adhesion System

The RadiSurf adhesion system is a 20-100 nm chemical coating on metal surfaces, allowing the direct application and strong adhesion of polymeric materials eg. thermoplastics and thermosets on dissimilar surfaces like metals. The system ultimately creates a chemical bond directly from the metal surface and into the plastic material.

  •  A very clean adhesion system, no special additives needed – perfect for medical and nutrition applications
  • Traditional methods used for the final adhesion (injection over-molding, compression molding, solvent welding etc.)
  • Low material consumption
  • Designed to meet the specific adhesion need
  • Strong adhesion on both polished and rough metal surfaces
  • Pre-coated metal surfaces are stable and can be stored for months 
  • The interface is stable up to high temperatures of at least 200°C (390°F) 
  • Allows a complete separation of metal surface preparation and the molding/coating step as the surface is stable
  • Easy and strong adhesion of polymers that are otherwise impossible or hard to bind to metal surfaces



The RadiPrime™ Metal-Epoxy Primer Systems 


The RadiPrime™ Metal-Epoxy Primer System promotes extremely robust, secure and stable bonding between metals and epoxies. Our nano-primers modifies metal surfaces so polymer brushes to be grown from them, ulitmately securing the metal surface with the epoxy layer in a velcro-like nanostructure.  Radically improve metal-epoxy adhesion capabilities, lower risk of epoxy underperformance all while achieving tighter bonding interface. Suitable even for smooth surfaces and difficult to bond metals.  

  • Suitable for bonding with almost any metal and metal alloy
  • Compatible with most types of epoxy-based adhesives/ coatings
  • Improvement in adhesive strength by up to 50%, depending on the metal alloy
  • Radical improvement in the adhesive stability, very low bonding failure rate
  • The primer layer is nanometer-thin & basically invisible
  • Greatly reduces need for mechanical surface pre-treatment (surface roughening) of the metal part
  • Fits easily into your manufacturing/ production process – RadiPrime treated surfaces are stable for months before final adhesion/ coating step, thus priming and adhesion can be done separately
  • The chemical priming process is well-developed and documented
