Description

Reliable Hardener for Polyester Resin Systems

The Würth Timbafill Hardener is a paste-form catalyst designed for initiating the curing process in unsaturated polyester resins, putties, and fillers. It ensures efficient and controlled polymerisation, producing strong and durable cured materials in automotive, construction, and woodworking applications.

Stabilised Benzoyl Peroxide Formula

With a composition of 50% benzoyl peroxide in a plasticiser base, the hardener offers a stable, homogenous formulation that avoids common separation issues. This guarantees consistent quality during storage and use, with improved handling safety compared to unstabilised peroxide pastes.

Consistent and Safe Application

The hardener is formulated for easy incorporation into polyester filler systems at the recommended 2% dosage ratio. Its smooth, uniform texture allows precise mixing without clumping, ensuring an even cure throughout the material. For convenience and traceability, it can also be supplied in coloured variants, giving clear visual confirmation during mixing.

Optimised for Metolux Fillers

Specifically developed for use with Metolux polyester-based fillers, Timbafill Hardener ensures strong bonding, efficient curing, and long-term durability. It is suitable for professional applications in body repair, wood filling, and general-purpose resin systems.
