Description

Tränklack Gegenstand des Hauptpatentes ist ein Tränklack auf Basis eines alkydharzmodifizierten Silikonharzes in Kombination mit Carbamidsäureharzen (Urethanharzen), welche Zusätze von Alkyltitanaten in Mengen von etwa 0,1 0/o enthalten.Impregnating varnish The subject of the main patent is an impregnating varnish based on an alkyd resin-modified silicone resin in combination with carbamic acid resins (Urethane resins), which contain additives of alkyl titanates in amounts of about 0.1%.

Es wurde nun gefunden, daß es gelingt, die Wärmebeständigkeit von solchen Tränklacken zu verbessern, wenn erfindungsgemäß als Kombinationskomponente ein Urethanformaldehydkondensationsprodukt, z. B. ein Butylurethanformaldehydharz, verwendet wird. It has now been found that the heat resistance of to improve such impregnating varnishes if according to the invention as a combination component a urethane-formaldehyde condensation product, e.g. B. a butyl urethane formaldehyde resin, is used.

So erwies sich beispielsweise ein Kombinationslack der aus 3 Teilen eines Silikonalkydharzes mit 250/, Alkydgehalt in 750!ojger Lösung in Toluol in Kombination mit 1 Teil eines Butylurethanformaldehydharzes in 750/dger Lösung in Xylol-Butanol erhältlich ist, und Zusätze von Alkyltitanaten in Mengen von etwa 0,1 °/o enthielt, gegenüber einer Temperaturbeanspruchung von 120 Tagen bei 230 C als beständig.For example, a combination paint consisting of 3 parts turned out to be of a silicone alkyd resin with 250% alkyd in 750% solution in toluene in Combination with 1 part of a butyl urethane formaldehyde resin in 750 / dger solution in Xylene-butanol is available, and additions of alkyl titanates in amounts of about 0.1%, compared to a temperature exposure of 120 days at 230 C as persistent.

Dieser Lack ist bezüglich seiner Rißfreiheit den Lacken, wie sie im Hauptpatent genannt worden sind, noch überlegen. With regard to its freedom from cracks, this paint is like the paints have been mentioned in the main patent, are still considered.
