BLUSYN is a polyester and viscose, 3D non-woven material, designed to remove medium to fine dust. The construction ensures the dust disappears with a single wipe. The BLUSYN tack rag removes fine particles in the approximate range P800 to P3,000. Where there is a mixture of particle sizes, wipe first with a NATGOZ tack cloth and finish with BLUSYN, which leaves no residue and only requires very light hand pressure across the surface. Whether painting, varnishing or lacquering by brushing or spraying, the one thing that is sure to ruin your finish is dust. You might not be able to see it, but be sure it is there, just lurking on the surface waiting to spoil your chosen finish. Wiping the dust rather than trying to blow it off the surface, locks the dust away preventing it re-settling elsewhere. Dust is an anathema, a Tack Rag is the solution. With over 40 years of production, Tack Rags know a thing or two about removing dust. These tack cloths remove particles of dust, dirt and lint that would otherwise contaminate a surface you intend to paint or varnish etc.-bg
