Surface preparation and protection is a core 3M strength. That’s why we can create solutions that meet the most challenging specifications for metal and composite aircraft engine nacelle systems. Our surfacing films can protect against lightning strikes and microcracks. Co-cure capabilities and virtually pinhole-free formulations can help increase build rates. The unique combination of stiffness and strength of our matrix resins can enable conversion of metal parts to composites for lightweighting. 3M has the broadest range of solutions for your aircraft engine design.

Thermally-expanding film adhesives meet the challenges of bonding wide honeycomb cores and structures, including resistance to temperature and fatigue.
3M™ Scotch-Weld™ epoxy and urethane paste adhesives are flexible to resist vibration and deliver outstanding environmental performance.
Low-density, temperature-resistant epoxy void filling adhesives are ideal for honeycomb reinforcement and filling mismatched areas on engine nacelles.
Chemical and UV resistant low-density films are co-cure compatible and available with lightweight mesh conductors for lightning protection. Not sure what product meets your needs? Choose the chart below to find the product that's right for your project.

Appropriate mixing of epoxy and hardener is critical to both the processing and performance of your finished composite part. 3M's Resin Calculator makes calculating the appropriate mix ratio simple. You will need the Certificates of Analyses that shipped with the resin and the hardener where you will find the Epoxy Equivalent Weight (EEW) for each component. Enter the two numbers in the appropriate boxes (Box 1 and Box 4 for the 3M Matrix Resin and Hardener respectively). In Box 2, enter your desired units of 3M Matrix Resin. The calculator will function whether you prefer to mix by volume or by weight. The Charge Ratio in Box 3 can be recommended by 3M Technical Support Personnel by calling 1-800-235-2376. The basic starting point for a Charge Ratio is 1.00. Resin performance can occasionally be improved with a slight under charge (0.95) or a slight over charge (1.05).
