Abstract:
The invention relates to a device for applying and/or spreading liquid or pasty substances for coating surfaces, especially paists, varnishes and lacquers on the surface of objects (2). The device has at least two pinions (7, 7′) the axes of which are arranged substantially parallel in relation to the object's surface to be coated. The spindles are provided with circumferential brush-like spreaders (8). At least one spindle can be moved across the surface of the object, with the object being moved along the brush-like spreaders.
Abstract:
The invention relates to air-drying and finishing coats for wood for exterior and interior finishes, comprising the so-called nonvolatile matter, which represents an intimate mixture of modified natural oils, pigments, extenders and small proportions of varnish additives, and a low-boiling petroleum hydrocarbon, which is suitable as a solvent and is present in an amount of .ltoreq.15% by weight, based on the total amount.An air-drying stain for exterior finishes is to be provided, with which a spotty or mottled appearance of the dried surface is avoided reliably even after a single coat of paint.This objective is accomplished by a stain, the mixture of chemically modified natural oils of which have a consistency, so that the efflux time from a DIN 53,211 4 mm viscosity cup is between 28 and 35 seconds, and the extender of which comprises a fine, cryptocrystalline, amorphous silicon dioxide, in which the proportion of particles with a particle size less than 40 .mu.m is greater than 95%.
