This invention relates to a new one-component stoving composition, which can be baked at low temperatures without the release of volatile compounds and which also has satisfactory stability when stored at room temperature. The invention also relates to the use of the one-component stoving composition.

One-component stoving composition and use thereof

Aqueous coating compositions containing urethane (meth)acylates having UV-hardening isocyanate groups

The present invention relates to (cyclo)aliphatic polyisocyanates which have a content of blocked and unblocked isocyanate groups (calculated a NCO) of 5 to 25 wt. %, in which at least 95% of the isocyanate groups are present in a form blocked with blocking agents, and which also contain 0.1 to 5.0 wt. % of amines having a structural unit corresponding to formula (I)

Stabilized blocked isocyanates and their use in polyurethane stoving lacquers

The present invention relates to transparent coating compositions containing a binder and 0.5 to 25 wt. %, based on resin solids, of a material consisting of nanoscale primary particles obtained by jet dispersion of the nanoscale particles in the coating composition. The present invention also relates to a process for the production of these transparent coating compositions containing nanoscale particles by passing the coating compositions containing nanoscale primary particles and a binder in at least one pass through an apparatus which has at least one nozzle or at least one slit having a bore diameter or slit width of 0.05 to 1 mm and a length to diameter ratio of the bore or a depth to slit width ratio of the slit of 1 to 10, wherein there is a pressure differential between the nozzle inlet and outlet of at least 0.5, preferably of 1 MPa.

Transparent coating compositions containing nanoscale particles and

This invention relates to polyisocyanates which are partially or completely blocked with 3,5-dimethyl-1,2,4-triazole, to heat curable, one-component coating compositions containing these blocked polyisocyanates and to the resulting coatings.

Polyisocyanates blocked with 3,5-dimethyl-1,2,4-triazole

The present invention relates to colloidal metal oxides having blocked isocyanate groups, which are based on the reaction product of

The present invention relates to polycyclic-iminooxadiazinediones corresponding to formula (I) ##STR1## to a process for their preparation and to their use for the production of polyisocyanate addition products.

Polycyclic iminooxadiazinediones, their preparation and use

The present invention relates to polyisocyanates prepared from diphenylmethane diisocyanate wherein at least 95% of the isocyanate groups are blocked with diethyl malonate and wherein the polyisocyanates have, based on solids,

Diphenylmethane diisocyanate based polyisocyanates containing

Polyisocyanates which have 1,2,4,-triazole-blocked isocyanate groups and a blocked isocyanate group content of 7 to 14 wt. % and which are reaction products of

Blocked polyisocyanates and their use in stoving lacquers

Blocked polyisocyanates containing aliphatically and/or cycloaliphatically bound isocyanate groups blocked by a mixture of blocking agents containing

Polyisocyanates blocked with a mixture of blocking agents

The present invention relates to heat curable coating compositions containing a binder consisting essentially of

Heat curable coating compositions and their use as top coats

Blocked (cyclo)aliphatic polyisocyanates wherein 30 to 70 equivalent-% of the isocyanate groups are blocked with butanone oxime, 30 to 70 equivalent-% of the isocyanate groups are blocked with 1,2,4-triazole and 0 to 30 equivalent-% of the isocyanate groups are blocked with other blocking agents; a method for their preparation by blocking lacquer polyisocyanates with these blocking agents, optionally with the prior, simultaneous or subsequent modification of the polyisocyanates with hydrazine derivatives containing one or more isocyanate-reactive groups; and the use of the blocked polyisocyanates as cross-linking agents for organic polyhydroxy compounds in one-component polyurethane stoving compositions.
