PhotoPrime SR enables over 90% reduction in frictional force on difficult-to-coat substrates such as PEEK, Polyimide, and Silicone. These substrates have low surface energy and are strongly hydrophobic; hence, they do not hold a lubricious coating easily. Conventional high-lubricity technologies typically achieve a coefficient of friction (CoF) from 0.25 to 0.45 on these substrates. PhotoPrime SR allows a durable hydrophilic coating to be applied and achieve coefficients of friction less than 0.02, as shown in the graphs below.
