Three Bond 2273E - 1K Epoxidharz (HF-Induktions-Cure) - 20 kg Eimer

Epoxy adhesive Three Bond 2273E at a glance

The one-component epoxy adhesive Three Bond 2273E is based on an epoxy resin and is solvent-free. With a solid content >99% it supports high strength with reduced shrinkage. As an HF induction cure system, it enables a rapid cure in seconds, which is advantageous especially for metal sheets, ferrite and steel parts.

The product is available in a 20 kg pail and is characterized by a bright, white color as well as good chemical and electrical resistance.

Suitable for metal joints and rapid HF induction curing

Metal joints

The adhesive is ideally suited for joining ferrite and steel components. The one-component system simplifies processing and reduces the need for mixing — especially where a quick start-up is required.

Structure and main components

The main component is an epoxy resin. The product is solvent-free and operates as a one-component system, enabling fast, reliable bonding. The color White facilitates visual inspection of the adhesive bond.

Properties and practical advantages

• High solid content provides robust and durable adhesive joints
• Low shrinkage minimizes stresses on sensitive components
• High electrical and chemical resistance increases reliability in demanding environments

Processing & Practice

Due to the HF induction cure, rapid curing is possible, resulting in short downtime. For best adhesion, surfaces should be clean, dry and free of oil or grease before application. Curing occurs at about 150 °C within around 30 minutes; afterwards the bond can be further loaded according to application requirements.

Special features

HF induction cure as a core feature enables seconds-fast curing in automated or on-site operation, particularly suitable for components with Fe-containing deposits (ferrite, steel). The system provides a reliable, epoxy-bonding adhesive solution with high long-term durability under operating conditions.
