High performance polymer surface modifications technology

To maximize both bio-compatibility and longevity Spectrum Medical has selected the Phosphorylcholine (PC) 1036 as its entry level bio-compatibility coating. PC1036 utilises an additional final step in the coating process to create a “cross-linked” structure within the coating substrate, providing significant advantages compared to the low-cost PC1059 alternative used by other manufacturers.

PC1036                                                                                     PC1059

Surface adhesion of the PC1036 is approximately 5 x greater than the PC1059.

The elastic behavior of the PC1036 bio-compatibility coating as shown below is fundamental improvement upon on the inelastic behavior of the low-cost PC1059.  This inherent elasticity and greater surface adhesion properties significantly improves long-term performance.

As can be seem from the data below that the Surface Roughness of the PC1036 is approximately 35 times less than the PC1059, which is a significant advantage to reducing hemolysis and increased clotting times.
