3M 90 Hi-Strength Clear Spray Adhesive – 500g Aerosol for Aerospace and Industrial Bonding
3M 90 Hi-Strength Spray Adhesive is a high-performance, clear contact adhesive in a convenient aerosol format, providing fast-drying, high-strength bonds across a wide range of porous and non-porous substrates. Its high-strength formula delivers superior holding power compared to standard spray adhesives, making it the preferred choice for aerospace insulation bonding, trim attachment, gasket fabrication, and composite panel assembly in production and MRO environments.
The aerosol delivery system provides a consistent, fine spray pattern that allows uniform adhesive coverage across large surface areas in a single application, significantly reducing application time compared to brush or roller adhesive methods. The clear formulation dries quickly to a transparent film that is invisible in the bonded joint, maintaining the appearance of finished assemblies.
3M 90 forms bonds by contact — adhesive is applied to both surfaces, allowed to flash off briefly, then the surfaces are brought together for immediate, strong bonding. This contact adhesive mechanism provides instant handling strength without the need for extended clamp time, enabling fast, efficient bonding in production and repair operations.

Technical Information
3M 90 Hi-Strength Spray Adhesive is based on a neoprene rubber contact adhesive chemistry that provides high initial tack and strong final bond strength across a broad substrate range. The adhesive builds its strength through the crosslinking of neoprene polymer chains at the bonded interface, creating a flexible, durable adhesive film that maintains bond integrity under vibration, thermal cycling, and mechanical stress.
The aerosol propellant system delivers a controlled spray pattern that can be adjusted from a narrow focused stream to a wide fan pattern depending on application technique and can distance from the surface. For large bonding areas, a wider fan pattern minimizes application time. For smaller, precise applications, a narrower stream provides targeted adhesive placement without overspray.
Contact adhesive application requires both surfaces to be coated with adhesive and allowed to flash off until dry to the touch before joining. This open time allows the solvent carrier to evaporate, leaving the adhesive film in an active state ready to bond immediately upon contact. Proper flash-off time ensures maximum bond strength — surfaces brought together while wet can result in weaker, solvent-trapped bonds.
