Improve Aircraft Coatings and Adhesives

Polymer-based coatings and adhesives play crucial roles in vehicle design and fabrication. Coatings provide protection from corrosion, scratching, UV, and aging while improving the appearance of the vehicle. Adhesives must provide strong bonding of components while maintaining light weight. Accelrys solutions enable you to understand and control polymer structure, properties, and processes.

Predicting the Binding Properties of Aircraft Coatings

Accelrys solutions can help you better ensure that your coatings adhere well to surfaces throughout the lifetime of your product by letting you predict the active surfaces of new structures, as well as the ways in which molecules will chemically or physically bind with the surfaces.

Predicting the Stability of Aircraft Coatings

You save months of time and effort in a research project by using Accelrys solutions to predict in silico whether a coating will be stable over time or whether elements will begin to crystallize out.

Improving Aircraft Coating Resistance to Corrosion

Coatings are often used to protect surfaces from a hostile environment. Molecules such as oxygen and water can damage delicate metal components if they can penetrate through surfaces. Accelrys solutions can help you predict the diffusivity and solubility of small molecules or predict actual corrosion inhibition in complex systems.
