EFB Elektronik 353 Light Epoxy Resin 4g 2-Component Adhesive + Hardener

Bonding delicate electronics or repairing small components often fails when the adhesive is too thick, too visible, or takes too long to cure. The EFB Elektronik 353 Light epoxy resin solves this with a transparent, fast-setting two-component system that flows into tight spaces and cures at room temperature. This 4-gram kit includes resin and hardener in a 1:1 mixing ratio, giving you a strong, electrically insulating bond for metals, plastics, ceramics, glass, and wood. Its low viscosity makes it perfect for potting, encapsulation, and precision repairs where a clean, invisible join is essential.

Who is it for

Technicians, hobbyists, and professionals who need a reliable adhesive for electronics, model making, or general repairs will appreciate this epoxy. It is ideal for circuit board work, sealing connectors, fixing ceramic or glass items, and any task that demands a transparent, durable bond without the need for heat or special equipment.
