Epoxy Putty Technicoll E-574 — two-part repair filler 670 g & 330 g

Technicoll E-574 is a two-part epoxy putty supplied as 670 g and 330 g components that are mixed before application. It functions as a structural repair filler for bonding, gap filling and surface restoration on substrates such as metal, wood, stone and many plastics. After curing the material becomes hard and sandable, with resistance to moisture, making it suitable for patching, rebuilding worn parts and creating durable repairs where structural integrity and a smooth finish are required.

Advantages

The epoxy formulation provides strong adhesion to a variety of substrates and cures to a rigid, machinable material. Supplied in two measured components, the putty is ready to mix for a predictable cure and consistent mechanical properties. Once cured it can be sanded, drilled and shaped to restore profiles or fill voids. The cured surface demonstrates moisture resistance, enabling use in environments exposed to occasional water or humidity.

Suitable for

• Repairing and rebuilding metal parts with corrosion or wear damage
• Filling gaps and holes in wooden components before finishing
• Restoring stone or masonry details and small chips
• Bonding and filling many rigid plastics in non-structural assemblies
• Patching automotive and marine components where a sandable finish is needed

Key specifications

• Two-part epoxy system supplied as 670 g and 330 g components for mixing
• Cures to a hard, sandable material suitable for machining and shaping
• Adheres to metal, wood, stone and many plastics
• Resistant to moisture after full cure
• Suitable for gap filling, bonding and surface restoration

How to use

Prepare surfaces by cleaning off dust, grease, rust and loose material; roughen smooth surfaces to improve adhesion. Cut or measure the two components and mix thoroughly until a uniform colour and consistency is achieved. Apply the mixed putty to the repair area, pressing to ensure contact and shaping as required. Allow the material to cure fully according to ambient temperature and layer thickness before sanding, drilling or painting.

Usage recommendations

Use protective gloves and work in a well-ventilated area. For best results, perform test patches on the intended substrate to verify adhesion and cure time. Avoid application at temperatures below the manufacturer's recommended curing range and ensure surfaces are dry prior to application to maximise bond strength.
