siasponge makes for safer surface treatment
If you use the wrong abrasive, you can easily ruin the surface you are working. Grit identification can be difficult
due to dust. To avoid mixing up abrasives, sia Abrasives has developed a colour-coding scheme for its new siasponge foam abrasives. Each foam colour represents a specific grit range or grade – for every sanding application and for all materials. This prevents mistakes during surface treatment and makes the
sanding process quicker and less complicated.
The grit range classifications used for siasponge products are based on colour theory. The various grades of foam abrasives have been subdivided according to the colours of the spectrum. The coarsest abrasives (medium) are therefore orange, working all the way down to the finest grit (microfine), which is assigned to the colour violet. This distinctive colour scheme of the various abrasives significantly improves process reliability.
Due to their conformability, siasponge foam abrasives are the ideal choice for areas
that are difficult to access, and rounded or profiled surfaces. Workpieces such as door handle recesses, bumpers or radiator grilles are easier to work thanks to the flexible foam. Unlike
conventional sandpaper, siasponge can be folded without creating
permanent creases, which allows a more consistent surface finish due
to improved grain consistency without swirl marks. siasponge is designed for versatile use on plastics, composites, paints,
(old) varnishes, primer fillers and primer coats.
To ideally prepare the workpiece, the type of foam carrier used by siasponge is adapted to the application. The applied force is
dissipated throughout the 3-D structure creating a more consistent and
even pressure of grit on substrate.. This eliminates pressure points and prevents the abrasive grain from cutting too deeply into the substrate, resulting in an even scratch pattern due to improved grain consistency. The combination of foam and flexible grit binding also has the advantage that it reduces clogging of the abrasive. Abrasive dust is continuously removed from the cavities between the grits. This allows multiple use of the abrasive, which ultimately is an advantage in terms of cost.
sia Abrasives uses solvent-free binder resins in all its siasponge products. This helps to avoid unpleasant odours at the workplace and reduces potentially hazardous or explosive vapours.
The siasponge soft products by sia Abrasives are available in six grades with exclusive colour codings: coarse (red), medium (orange), fine (yellow), superfine (green), ultrafine (blue) and microfine (violet).
