Frequently asked questions about Permabond ES741
Practical application and design questions — answered by SILITECH.
Special 1K epoxy ES741 (700 series) — Engineering applications. 1K epoxies are processed directly without mixing and cured in a single heat-cure step.
One-component (1K) epoxies are processed directly from the container without mixing—no pot life limitations, no mixing errors. Disadvantage: Heat curing is required (industrial oven, IR lamp, or hot air). Two-component (2K) epoxies cure at room temperature but require precise mixing and have a limited pot life. One-component (1K) epoxies are suitable for line production with heat-curing infrastructure, while two-component (2K) epoxies are suitable for workshops without an oven.
Heat curing. For exact conditions, see Permabond-TDS — typically 30 minutes at 150 °C or equivalent heat input (e.g. 60 min @ 120 °C).
One-component heat-cure epoxies bond metals (steel, aluminum, copper), composites (CFRP, GFRP), ceramics, and selected heat-resistant plastics. Substrates must tolerate the curing temperature (typically 150 °C).
Permabond ES741 does not have specific industry approvals such as UL94-V0 (see ES578 for the flame-retardant variant). For general industrial applications, the product is approved according to Permabond standards.
Store between 5 and 25 °C. 1K heat-cure epoxies have limited storage stability—reactivity decreases with increasing storage temperature. For long shelf life, store refrigerated. Allow the adhesive to warm to room temperature before opening.
From the Permabond 1K epoxy range: Permabond ES741 (Special 1K Epoxy 700 series (Engineering)); Permabond ES550 (Standard 1K); Permabond ES578 (UL94-V0); Permabond ES560 (Engineering). For UL94-V0 fire protection, see ES578; for high temperature, see ES566/ES569; for IR/hot air curing (without an industrial oven), see ES5691.
