Description

Spiegelschutz Spiegel erlialtett oft im lauf der Zeit fleckige oder blinde Stellen, insbesondere wenn sie feuchter Luft oder (lern Wetter ausgesetzt sind. Dies tritt auch dann ein, wetttt die Spiegel, wie üblich, mit einem Lacküherztrg versehen sind. Es wurde nun gefunden, dal.i `Riegel gegen diesen Übelstand vorzüglich geschlitzt sind, wenn sie auf ihrer Rückseite einett Cbcrzug aus einem praktisch wasserundurchlässigen Polvtncrisat erhalten. Ge- eignete derartige 1'olymcrlate sind beispielsweise f'olvvinvlchlorid, l'olyäthylett oder 1'olyisohutylen. Besonders wirksam geschieht der Schutz durch Folien aus solchen Polvrnerisaten. die mit den für diese gchräuchlicheti Klebestoffen aufgeklebt sind. _\tn bestell ist es, wenn auch das Klebemittel selbst aus einem wasscrundurcltliissigen 1'olvmcrisat lw- steht. Mit Vorteil verwendet man solche Folien, auf die lwmits eine lösungsmittelfreic Klebeschicht aufgebracht ist, z. 13. diintte Folien aus Polyvinvl- chlorid, die mit einer Klebeschicht aus Polyacrvl- siittrcl>tttvlester versehen sind. So geschützte Spiegel werden selbst nach langer Zeit unter den ungünstigsten Witterungsverhält- nissen und unter besonders starker Einwirkung von Feuchtigkeit nicht blind oder fleckig, während ver- gleichsweise Spiegel ohne eine solche Folie bereits nach einigen Monaten fleckig oder sogar blind und unbrauchbar sind.Mirror protection Mirrors often become blotchy over time or blind spots, especially if they are more humid Exposed to air or weather. This occurs even then, the mirror, as usual, bets with it are provided with a lacquer core. It has now been found that there is a bolt against this Evil are excellently slashed when on its back is made of a practical obtained waterproof polvtncrisat. Ge suitable such 1'olymcrlates are, for example f'olvvinvlchlorid, l'olyäthylett or 1'olyisohutylen. Protection is particularly effective through Foils made from such pole pieces. those with the for these common adhesives are glued on. _ \ tn order it, even if the adhesive itself from a water-based 1'olvmcrisat lw- stands. It is advantageous to use such foils, A solvent-free adhesive layer on the canvas is applied, e.g. 13.thick foils made of polyvinyl chloride, which is coated with an adhesive layer of polyacrylic siittrcl> tttvlester are provided. Mirrors protected in this way will last even after a long time Time under the most unfavorable weather conditions nits and under particularly strong influence of Moisture is not blind or blotchy, while likewise mirrors without such a film already are blotchy or even blind and unusable after a few months.
