Bonding G10 to metal requires the right balance of adhesion, thermal performance, chemical resistance, and processing practicality.
This page outlines the main decision factors engineers should consider when selecting an adhesive for G10-to-metal assemblies.
G10 is a fiberglass-reinforced laminate with very different surface behavior than aluminum, steel, or plated metals. Adhesive selection depends on bond strength targets, temperature, exposure conditions, and whether the bond is permanent or temporary.
Different metal finishes and G10 surface conditions can significantly change wetting and adhesion performance.
Differences in expansion between composite and metal can place stress on the adhesive bond line.
Cure speed, gap fill, fixture time, and dispensing method often narrow the list of viable options.
The best adhesive depends on the application, not just the substrates.
Consider both continuous exposure and short-term temperature spikes. High heat may eliminate lower-performance chemistries.
Define whether the bond must resist peel, impact, vibration, shear, or long-term static load.
Oils, cleaners, water, fuels, and shop chemicals can strongly affect long-term bond durability.
Dispensing, fixture time, cure method, and production throughput all matter when narrowing candidate materials.
Epoxies are often evaluated for strength and chemical resistance, acrylics for speed and difficult-to-bond substrates, and urethanes when flexibility or impact resistance is important.
