The West System 403 Microfibres are very fine cellulose fibres used to create structural adhesives with excellent gap filling properties for bonding most boat building materials including both wood and GRP. Microfibres is an excellent choice when bonding porous materials such as wood because the fibrous nature of the the filler retains a significant quantity of epoxy within a joint and limits resin absorption into the surrounding surface ensuring an adequate resin supply for adhesion. Where the strongest bond is required, e.g. timber scarf joints, microfibres are the best option.
