    Epoxy Filler – SP Microfibers 500gm

    23.50 19.86 (ex vat)

    SP Microfibres are very fine wood-cellulose fibres commonly used to create structural adhesives for bonding both wood and grp.

    Because any low viscosity resin system is readily absorbed into a porous surface such as wood, an unfilled adhesive may tend to give a ‘dry joint’. With their absorbent properties, microfibres can retain a significant quantity of adhesive within a joint and limit resin absorption into the surrounding surface, thus ensuring an adequate resin supply for adhesion. Where the strongest bond is required, e.g. timber scarf joints, microfibres should always be used in preference to hollow sphere-types of filler.

    For bonding parallel to the grain with lower density, lower strength timbers, such as cedar or obeche, a microballoon mix is often adequate, and is of lower density. Weight – 500gm

    Technical Details;

    Composition: Milled bleached cellulose wood pulp
    Appearance: White ‘fluffy’ fibrous consistency
    Particle Size: 200 – 300 microns
    Particle Density: Particles absorb resin
    Bulk Density: 100g/litre approx.

    Colloidal Silica + Microfibres + Epoxy = Adhesive Mix

    Epoxy Filler – Glass Bubbles 300gm

    28.76 22.45 (ex vat)

    SP Glass Bubbles are hollow glass spheres with a more variable particle size than microballoons. Being composed chemically of glass, they are physically harder than microballoons and filled resin mixes are noticeably more difficult to sand. However, glass bubbles produce a more waterproof filler mix and are often used on below-waterline applications on boats. Being significantly less expensive than microballoons  they are often preferred if easy sanding performance is not of prime importance. They can be mixed with microballoons in any proportion for colour purposes.

    Technical Details:

    Composition: ‘C’ Glass
    Appearance: White powder
    Particle Size: 40 – 80 microns
    Particle Density: 200g/litre approx.
    Bulk Density: 100-150g/litre approx.
