Frequently Asked Questions About Permabond ES741
Practical questions regarding application and design — answered by SILITECH.
Specialty 1K Epoxy ES741 (700 Series) — Engineering Applications. 1K epoxies are applied directly without mixing and cured in a single heat-curing step.
1-component epoxies are applied directly from the container without mixing—no pot life limitations, no mixing errors. Disadvantage: Heat curing required (industrial oven, IR lamp, or hot air). 2K epoxies cure at room temperature but require precise mixing and have a limited pot life. 1K is suitable for production lines with heat-cure infrastructure; 2K is suitable for workshops without an oven.
Heat curing. For exact conditions, see the Permabond Technical Data Sheet (TDS)—typically 30 minutes at 150 °C or an equivalent heat input (e.g., 60 min @ 120 °C).
1K heat-cure epoxies bond metals (steel, aluminum, copper), composites (CFRP, GFRP), ceramics, and select plastics (with heat resistance). Substrates must be able to withstand the curing temperature (typically 150 °C).
Permabond ES741 does not have any specific industrial certifications such as UL94-V0 (see ES578 for the flame-retardant version). For general industrial applications, the product is approved according to Permabond standards.
Store at 5 to 25 °C. 1K heat-cure epoxies have limited storage stability—reactivity decreases as storage temperature increases. Store in a cool place for extended shelf life. Allow the adhesive to warm to room temperature before opening.
From the Permabond 1K epoxy series: Permabond ES741 (special 1K epoxy, 700 series (engineering)); Permabond ES550 (standard 1K); Permabond ES578 (UL94-V0); Permabond ES560 (engineering). For UL94-V0 flame retardancy, see ES578; for high temperatures, see ES566/ES569; for IR/hot-air curing (without an industrial oven), see ES5691.
