For secondary bonding we recommend Compoflex®SB 400. Release film perforation style: Medium bleed characteristics.
Compoflex® 400 is a high weight breather (300g / 10 oz) ideal for medium or high pressure cures and can be used as bleeder at any pressure.
Works well with polyester, vinylester, epoxy, phenolic and other types of resin.
Working temperature
Recommended max. working temperature is 144°C (293°F). The melting point for polypropylene is 165°C (329°F). However, it is possible to use Compoflex® at 200°C (392°F) due to the fact that Compoflex® performs before the temperature exceeds the melting point. After cooling, the material becomes stable again, and peeling is just as easy as normal. We recommend conducting a test on a small part first.
