SR 330 Primer

PhotoPrime® SR 330 Primer

PHOTOPRIME® SR enables over 90% reduction in frictional force on even the most challenging substrates such as PEEK, Polyimide, and Silicone. These substrates have low surface energy and are strongly hydrophobic; 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.

High performance primer
for difficult-to-coat substrates

PHOTOPRIME® SR 330 primer leverages ISURTEC’s patented Affinity-Based Technology (ABT) for high performance bonding of your desired topcoat to even the most challenging substrates. PHOTOPRIME® SR pairs well with the ISURGLIDE® 460 family of lubricious coating solutions. It may be applied using common medical device coating procedures – dip coating followed by UV cure to covalently bond the coating to the device.

PHOTOPRIME® SR is designed to work with:

Outstanding Lubricity and Durability

The graphs below illustrate Industry standard lubricity and durability testing conducted on two commonly used medical device substrates. Each substrate was primed with PHOTOPRIME® SR 330 and given a top-coat of ISURGLIDE® 460 hydrophilic coating. Testing was performed with a commercial Friction Test System set with 500 grams clamping force.
