aircraft fan blade using 3M cocure solutions

Advanced Composite Protection

Extend the life of composite parts with 3M™ Cocure.


Increased aircraft composite materials usage has posed new challenges for OEMs and airlines, because composites are more susceptible to erosion than aluminum or titanium and therefore require enhanced protection.  Decrease downtime and reduce paint and composite repair costs by harnessing the power of 3M™ Cocure. This revolutionary integrated system leverages durable, lightweight aerospace grade UV stable protective film that can withstand extreme temperatures up to 400˚F and is repairable with two-part 3M™ Scotch-Weld™ Repair Paste.

  • Comparison of Cocure films from 3M outperforming paint by 60x.

    3M™ Cocure films outperform paint by 60x.

    During a sandblasting test, paint fails after just 9 seconds. 3M™ Cocure and Repair Paste provide protection for up to 9 minutes.

    3M™ Cocurable Polyurethane Erosion Resistant Films

    Protect your aircraft from abrasion, erosion and particulate impacts. These films are designed to be cured into the composite part during fabrication using the resin system of the composite part being manufactured. This material may also be post bonded to composite parts using a 3M adhesive film. Erosion protection can be tailored to the expected erosion intensity by curing a thinner version over a thicker version while not creating a step height change in the installed protection. There’s also the potential to eliminate painting when the cocure film is the color of the finished part. Click the links below to learn more about some of our signature products.
