Urethane modified water-reducible alkyd resins ABCD, comprising moieties derived from polyhydric alcohols A, modified fatty acids B made h&#x3b3; grafting olefinically unsaturated carboxylic acids B2 onto fatty acids B1, ungrafted fatty acids C and polyfunctional isocyanates D, a process for their production, and a method of use thereof in coating binders

Urethane modified water-reducible alkyd resins

Urethane and siloxane modified water-reducible alkyd resins ABCDE, comprising moieties derived from polyhydric alcohols A, modified fatty acids B made by grafting olefinically unsaturated carboxylic acids B2 onto fatty acids B1, ungrafted fatty acids C, silanol or alkoxysilyl functional siloxane oligomers or polymers D, and polyfunctional isocyanates E, a process for their production, and a method of use thereof in coating binders.

Polysiloxane and urethane modified water-reducible alkyd resins

The invention relates to hydroxyl-functional binder components ABC containing a linear or branched main chain having a polymethylene structure &#x2014;(CH)&#x2014; or a polyester structure or a structure derived from the fatty acid esters of glycerin or other polyvalent alcohols. The invention is characterized in that said components have grafted cyclic imide structures on the main chain, wherein the imide-nitrogen atom is substituted by a hydroxyalkyl group or a hydroxyalkyl-aryl group. The invention also relates to method for the production of said components by reacting oleofinically unsaturated acid anhydrides B and hydroxyamines C and to the utilization of the inventive components for the formulation of binders.

Hydroxy-functional binder components

A water-dilutable polyester resin ABCD having a mass fraction of from 1 to 10% of units derived from unsaturated cocondensed building blocks, an olefinic double bond content of from 10 to 2 000 mmol/kg, and a sulfonic acid group content of from 20 to 300 mmol/kg, modified if desired by copolymerizing olefinically unsaturated monomers in the presence of the polyester resin, a process for preparing them, and their use in particular in one-component coating compositions in combination with amino resin curatives.
