Description

Wrightlon® 3900 release film is a high elongation film which will exhibit excellent release properties from polyester, vinyl ester and epoxy resin systems. It will take temperatures up to 157°C (315°F). It is also suitable for compaction and debulking operations. All standard perforations are available. Please see our perforation table in this section.

Benefits

• Good elongation reduces bridging in corners, so less rework on resin rich corners.
• Highly visible colour reduces risk of leaving film on cured parts.
• Inexpensive film reduces the cost of medium temperature vacuum bagging processes.
