Pigmented Multifunctional Barrier Coating for Aircraft Interiors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current barrier coatings for aircraft interiors do not provide a singular composition that simultaneously offers cosmetic performance, damage protection, antimicrobial properties, and flame, smoke, and toxicity (FST) performance, leading to the need for multiple layers and complex fabrication processes.
Innovation Solution
A pigmented multifunctional barrier coating composition that includes a base coating component, solvent, FST resistive component, UV resistive component, antimicrobial component, and a dye component, along with a pigment component, to form a cosmetic and performance-based barrier coating in a single application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate coating layers are applied to achieve different functions (FST performance, antimicrobial properties, cosmetic appearance), then each specific performance requirement is met, but the fabrication process becomes complex, time-consuming, and costly
Solution Approach 1:
The patent combines multiple separate coating layers (FST coating, antimicrobial coating, cosmetic coating) into a single integrated coating composition that simultaneously provides flame/smoke/toxicity resistance, antimicrobial properties, and cosmetic appearance in one application step
Solution Approach 2:
The coating composition is designed to perform multiple functions simultaneously: it provides FST performance through flame retardant components, antimicrobial protection through biocidal agents, and cosmetic appearance through pigments and clear coat formulation, making a single coating system universal for multiple requirements
2Shape
If intermediate cosmetic processes (painting, powder coating, metallization) are applied before barrier coating, then cosmetic appearance is achieved, but the overall fabrication process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the cosmetic coating function with the barrier coating function into a single composition, eliminating the need for separate intermediate cosmetic processes like painting or powder coating that would otherwise be required before applying the barrier coating
Solution Approach 2:
The coating composition is formulated in advance to contain all necessary components (flame retardants, antimicrobial agents, pigments, binders) so that a single application step simultaneously achieves both cosmetic appearance and protective barrier functions, preventing the need for subsequent intermediate processes
3Reliability
If a clear barrier coating is applied to protect component surfaces, then FST performance and cleanability are improved, but cosmetic appearance may be compromised due to color and sheen interference
Solution Approach 1:
The coating is designed to simultaneously provide protective barrier functions (FST performance, cleanability) and cosmetic functions (color matching, sheen control) through its multi-component formulation, making it suitable for both protective and aesthetic applications
