Permabond ET00503K050C0101, ET503 Fast Curing Epoxy, 50ml Kit, Case of 25
Permabond ET503 is a two-part, fast-curing epoxy adhesive that delivers high strength structural bonds on metals, composites, ceramics, glass, and most rigid plastics. Its rapid room-temperature cure makes it ideal for production environments where throughput is critical, while its excellent chemical and environmental resistance ensures long-term bond durability in demanding industrial applications. The 50ml dual-cartridge kit format provides convenient, mess-free dispensing with consistent mix ratios at the point of application.
Sold in cases of 25 x 50ml dual-cartridge kits.

Frequently Asked Questions
How fast does Permabond ET503 cure?
ET503 is formulated for fast room-temperature cure, achieving handling strength in minutes and full cure within hours depending on temperature and bond line thickness. Higher ambient temperatures accelerate cure; lower temperatures slow it. For the fastest cure, ensure the substrate and adhesive are at room temperature (70°F / 21°C) or above before application.
What is the mix ratio for ET503 and how is it dispensed?
ET503 is dispensed from a dual-cartridge kit using a standard epoxy dispensing gun with a static mixing nozzle, which ensures accurate, consistent mixing at the point of application with no manual mixing required. Always use a fresh static mixing nozzle for each application session to prevent the nozzle from curing shut between uses.
What substrates does Permabond ET503 bond?
ET503 bonds metals (steel, aluminum, copper, brass), composites, ceramics, glass, and most rigid plastics. Surface preparation is important for maximum bond strength — surfaces should be clean, dry, and free of oils, oxides, and contaminants. Light abrasion of metal surfaces before bonding is recommended for optimal adhesion.
When should I choose ET503 over a cyanoacrylate or acrylic adhesive?
Choose ET503 when you need a structural bond with high chemical resistance, gap-filling capability, and long-term environmental durability. Epoxies like ET503 excel in applications involving chemical exposure, elevated temperatures, or large bond gaps. Cyanoacrylates are faster but have lower gap-fill and chemical resistance; acrylics offer more flexibility and peel strength. ET503 is the right choice for rigid, high-strength structural assemblies.
