Process for the preparation of cationic laquer/binders for the formulation of pigment/pastes for electrodepositable, cathodic laquers

摘要

The invention relates to a process for the preparation of cationic paint binders which are particularly suitable for the formulation of pigment pastes for cathodic electrodeposition coatings. …??The paint binders prepared according to the invention are modified epoxy resin/amine adducts containing organochemically bonded titanium. …??The cured paint films provide excellent corrosion protection on un-pretreated steel sheeting even without the use of lead-containing compounds and/or lead pigments.
