LACKBINDEMITTEL UND DEREN VERWENDUNG

摘要

Lacquer binder is based on a mixt. of 10-90 (wt.)% anionic film-forming binder(s), opt. contg. max. 40% thermosetting phenolic and/or aminoplastics precondensate, and 90-10% hydrocarbon oil(s), which is liq. at room temp. and has a viscosity of 300-45,000 mPas at 25 degrees C. The binder is specified for use for anodic electro-dip lacquering of conducting articles in its water-dilutable form, obtd. by addn. of NH3 or a water-soluble volatile amine. It can also be used as adjesive, e.g. in the prodn. of chipboard, and as important impregnant for finishing fibrous materials, e.g. organic or ceramic textiles. It forms stable baths and coating with superior properties, e.g. corrosion protection and baking temp. The current consumption is reduced and the throw much better, whilst the coatings are more uniform and insensitive to sec. impurities (flying dust etc.) before and during baking.
