The RadiPrime™ Metal-Epoxy primer system is a nano-primer layer that modifies surfaces, enhancing Stainless Steel-epoxy adhesion. Epoxies can now reach its maximum adhesion strength.
Stainless steel is resistant to corrosion and rust, can be easily sterilized and recycled, therefore commonly used for surgical and medical equipment, construction material and in automotive and aerospace applications. Not only will the RadiPrime™ adhesive primer system greatly enhance how stainless steel can be used in these applications, but it is also chemically clean and ultra-thin – perfect for such applications.
Improvement in tensile shear strength
When testing the RadiPrime™ metal-epoxy primer on stainless steel, tensile shear strengths of 24 – 26 MPa for both the non-modified and the modified samples, were achieved, but on average the modified samples had 10% stronger performance than non-modified samples.
The maximum adhesion strength of the epoxy can be reached with the RadiPrime metal-epoxy primer
The RadiPrime™ Metal-Epoxy primer effectively improved epoxy bonding with stainless steel as shown by tensile strength tests. Fractures occurred mainly fully or partially in the epoxy, meaning the epoxy had reached its maximum adhesion limit and was the one to break, instead of the epoxy separating from the metal prematurely due to poor bonding.
