The 3M™ Accuspray™ Atomizing Head Refill Kit contains replaceable heads for the application of very low- to high-viscosity coatings with the 3M Accuspray ONE Spray Gun (sold separately). With the fast, simple change of a head, it will help improve your existing spray gun’s performance. The see-through design makes it easy to see if the heads are dirty and if so, the heads may be cleaned and reused. The 1.3mm heads are green to distinguish their size from others and contain atomizing air holes in the air caps to help achieve a high-finish quality. They are ideal for low-viscosity coatings and reduced overspray in hot and humid environments. Use the 1.3 mm heads to apply waterborne and solvent basecoat paints in thin clear coats, as well as stains, varnishes, mold release agents, aerospace and marine topcoats, and other fluids requiring very fine atomization.
